<p> Accessibility support remains a top engineering priority. Accordingly, we enhanced keyboard navigation/screen reader support, extended automation capabilities and other accessibility-related features to ensure better compliance with
standards outlined in WCAG. </p>
<p> This release includes enhancements across most of our desktop and web component suites: </p>

<a name="devexpress-dateonly-timeonly-support" class="anchor"></a>Support of New .NET DateOnly and TimeOnly Types Across UI Platforms
</h3>
<p> We now support <code data-renderer="hljs" class="csharp" data-control="Code-Inline">DateOnly</code> and <code data-renderer="hljs" class="csharp" data-control="Code-Inline">TimeOnly</code> types in data-aware UI controls (such as Data
Grid, Tree List, Date and Time Editors) for the following UI platforms in .NET Core / .NET 6+ apps. </p>
<ul>
<li><a href="#winforms-dateonly-support">WinForms Controls</a></li>
<li><a href="#wpf-dateonly-support">WPF Controls</a></li>
<li><a href="#blazor-grid-dateonly-timeonly-support">Blazor UI Components</a></li>
<li><a href="#xaf-dateonly-timeonly-support">XAF - Cross-Platform .NET App UI (Blazor)</a></li>
</ul>
<p><span class="FootNote"> * Please review the links above for additional information (supported features vary across UI platforms and controls). </span></p>
<p> Thanks to changes at core levels (our DevExpress.Data and DevExtreme.AspNet.Data libraries), we now support these data types for our client/in-memory and server mode data sources (both of which are used by multiple UI controls listed
above): </p>
<ul>
<li>EntityServerModeSource / EntityInstantFeedbackSource</li>
<li>LinqServerModeSource / LinqInstantFeedbackSource</li>
<li>GridDevExtremeDataSource (for ASP.NET Core / DevExtreme and Blazor-based controls)</li>
</ul>
<p> You can sort, group, and filter data (and other capabilities) against DateOnly and TimeOnly values. We also extended our
<a href="https://docs.devexpress.com/CoreLibraries/4928/devexpress-data-library/criteria-language-syntax?v=24.1" target="_blank" rel="noopener">criteria language</a> as follows: </p>
<ul>
<li>
<p> You can use date/time-related functions (such as AddHours, GetDays, DateDiffDays, etc.) in filter expressions and unbound columns. </p>
</li>
<li>
<p> You can now wrap DateOnly/TimeOnly constants in '#' and '!' for string filter expressions: </p>
<p><code data-renderer="hljs" class="csharp" data-control="Code-Inline">[<span class="hljs-meta">OrderDate</span>] >= <span class="hljs-meta">#!2018-03-22!# && [OrderTime] >= #!18:22:00!#</span></code></p>
</li>
</ul>
<p> Due to the following Microsoft-related breaking change these new data types are of special importance to EF Core 8 developers:
<a href="https://learn.microsoft.com/en-us/ef/core/what-is-new/ef-core-8.0/breaking-changes#sqlserver-date-time-only" target="_blank" rel="noopener">SQL Server date and time now scaffold to .NET DateOnly and TimeOnly</a>. DevExpress
customers will benefit from this new functionality even if NOT using EF Core 8 for data access – it is just important that the underlying database or IQueryable provider supports the new data types (like Microsoft SQL Server with EF
Core 8). Here is a quote from Microsoft about the general value for .NET developers: </p>
<div class="Attention">
<p><a href="https://learn.microsoft.com/en-us/dotnet/api/system.dateonly" target="_blank" rel="noopener">DateOnly</a> and <a href="https://learn.microsoft.com/en-us/dotnet/api/system.timeonly" target="_blank" rel="noopener">TimeOnly</a>
were introduced in .NET 6.0, and are a perfect match for mapping the database date and time types. <code data-renderer="hljs" class="csharp" data-control="Code-Inline">DateTime</code> notably contains a time component that goes unused
and can cause confusion when mapping it to date, and <code data-renderer="hljs" class="csharp" data-control="Code-Inline">TimeSpan</code> represents a time interval - possibly including days - rather than a time of day at which an
event occurs. Using the new types prevents bugs and confusion, and provides clarity of intent. </p>
</div>
<p><strong>Note</strong>: Microsoft and third-party package vendors did not backport DateOnly and TimeOnly types on .NET Framework. Additionally, we do not officially support this feature for .NET Framework and OData/XPO data sources
within both frameworks. We encourage you to migrate to .NET 6+ to benefit from the new data types. Technically, we share parts of our codebase between .NET Framework and .NET, so do not be confused that our DevExpress.Data library for
.NET Framework includes our own "shim" DateOnly and TimeOnly types. If you experience any conflicts with third-party compatibility packages (like one or two for unofficial support), we recommend that you remove these packages. </p>

</h3>
<p> In our v24.1 release cycle, the following DevExpress products will use Microsoft’s System.Text.Json instead of Newtonsoft.Json for JSON serialization-related tasks in <strong>runtime code</strong>: </p>
<ul>
<li>
<p> Data Access Library: BI Dashboards (DashboardJsonDataSource) and Reporting (JsonDataSource) for .NET 6+ WinForms, WPF, Blazor, ASP.NET Core apps (.NET Framework apps will continue to use the Newtonsoft.Json library. We expect to
switch to System.Text.Json in our v24.2 release cycle).

</li>
<li>
<p> Data Access Library for .NET 6+ and .NET Framework DevExtreme, Blazor and ASP.NET Core apps (a System.Text.Json-compatible version of
<a href="https://www.nuget.org/packages/DevExtreme.AspNet.Data/4.0.0-beta" target="_blank" rel="noopener">DevExtreme.AspNet.Data v4.0.0+</a> is now available).
<br><a href="https://supportcenter.devexpress.com/ticket/details/t1227758/devextreme-devextreme-aspnet-data-processing-and-serialization-now-use-system-text-json" target="_blank" rel="noopener">Breaking Change</a></p>
</li>
<li>
<p> Backend Web API Service for .NET 6+ non-XAF apps (DevExtreme, Blazor, .NET MAUI, etc.) and XAF apps.
<br><a href="https://supportcenter.devexpress.com/ticket/details/t1225165/xaf-system-text-json-library-is-used-to-deserialize-input-parameters-of-the-web-api" target="_blank" rel="noopener">Breaking Change</a></p>
</li>
<li>
<p> Maps in .NET 6+ WinForms in WPF, Blazor, ASP.NET Core apps (.NET Framework apps will continue to use the Newtonsoft.Json library. We expect to switch to System.Text.Json in our v24.2 release cycle).
<br><a href="https://supportcenter.devexpress.com/ticket/details/t1225036/system-text-json-is-used-to-process-the-vector-tile-styles-instead-of-the-newtonsoft" target="_blank" rel="noopener">Breaking Change</a></p>
</li>
<li>Blazor Rich Text Editor (no Breaking Changes).</li>
</ul>
<p> Our design-time code (wizards, designers and tools) may still continue to use Newtonsoft.Json, because of dependencies within Visual Studio (some design-time services still rely on Newtonsoft.Json, but we believe this will change in
the future). Remaining .NET Framework products that currently rely on the Newtonsoft.Json library, will likely switch to System.Text.Json in the future. Here we rely on the
<a href="https://learn.microsoft.com/en-us/lifecycle/products/microsoft-net-framework" target="_blank" rel="noopener">minimally supported .NET Framework version</a> for DevExpress products, which will likely change from 4.5.2 to 4.6.2
in v24.2. </p> <span class="H-Separator"></span>

</h4>
<p> The DevExpress WinForms Spreadsheet ships with enhanced filter and sort-related capabilities. We added new APIs that can sort and filter workbook data by background and font color. Cell ranges filtered/sorted by cell color can also be
printed and exported to PDF. </p>
<p> Our Sorting APIs include new <a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.Worksheet.Sort.overloads?v=24.1" target="_blank" rel="noopener">Worksheet.Sort</a> method overloads designed to sort a specified
range by font color or fill setting (background color and pattern). </p>
<p> The following code snippet sorts cell values across two cell ranges - the first is sorted by a red font color and the second is sorted by fill settings specified for the first cell in the range: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">spreadsheetControl.LoadDocument(<span class="hljs-string">"sort-filter.xlsx"</span>);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
<span class="hljs-comment">// Sort cell range by font color </span>
worksheet.Sort(worksheet[<span class="hljs-string">"B2:B10"</span>], Color.Red);
<span class="hljs-comment">// Sort cell range by fill color</span>
worksheet.Sort(worksheet[<span class="hljs-string">"D2:D10"</span>], worksheet[<span class="hljs-string">"D2"</span>].Fill);</code></pre>
</div>
</div>
<p> To filter cells by font or background color, you need to apply an auto-filter to the required cell range or table. Once complete, you need to obtain the required column from the <code data-renderer="hljs" class="csharp"
data-control="Code-Inline">AutoFilter.Columns</code> collection and call one of the following methods: </p>
<ul>
<li><a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.AutoFilterColumn.ApplyFillColorFilter(System.Drawing.Color)?v=24.1" target="_blank" rel="noopener">AutoFilterColumn.ApplyFillColorFilter(Color)</a></li>

</ul>
<p> The following code snippet uses these methods for both cell range and table: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">spreadsheetControl.LoadDocument(<span class="hljs-string">"sort-filter.xlsx"</span>);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
<span class="hljs-comment">// Apply an auto-filter to a cell range and filter the first column by font color</span>
worksheet.AutoFilter.Apply(worksheet[<span class="hljs-string">"B1:B10"</span>]);
worksheet.AutoFilter.Columns[<span class="hljs-number">0</span>].ApplyFontColorFilter(Color.Red);

table.AutoFilter.Apply();
table.AutoFilter.Columns[<span class="hljs-number">0</span>].ApplyFillColorFilter(Color.Red);</code></pre>
</div>
</div>
<p> In addition, our new APIs allow you to sort data across a filtered range (when auto-filter is enabled) and sort cells by their values/colors simultaneously (using sorting conditions). </p>

<p><strong>TabPane & NavigationPane</strong></p>
<p> We added keyboard navigation support to our WinForms TabPane and Navigation Pane controls (much like that of the XtraTabControl). Keyboard focus is now managed as follows: </p>
<ul>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">Right</code>/<code data-renderer="hljs" class="csharp" data-control="Code-Inline">Left Arrow</code> — Activates the Next/Previous page.</li>

<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">Home</code> — Activates the first page.</li>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">End</code> — Activates the last page.</li>
</ul>
<p> Additional API includes: </p>
<ul>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">AllowNavigationThroughPages</code> — Activate this option to focus the tab header (rather than the UI control displayed on the page) when the user navigates using
the Tab key. This option is disabled by default.</li>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">ShowHeaderFocus</code> — Displays/hides the focus rectangle.</li>
</ul>
<p><strong>TextBox-based Data Editors in BarEditItems</strong></p>
<p> We improved keyboard navigation within our Ribbon UI and Toolbars. Keyboard focus is now appropriately managed to mimic behaviors found in Microsoft Word. Specifically, when the BarEditItem has focus and the user presses an arrow key,
the BarEditItem retains focus, allowing navigation within the editor. </p>

<p> v24.1 exposes new properties that allow you to suppress a keyboard key (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">Alt</code> or <code data-renderer="hljs" class="csharp"
data-control="Code-Inline">Control</code>) for bar items with embedded editors (BarEditItem): </p>
<ul>
<li><a href="https://docs.devexpress.com/WindowsForms/DevExpress.XtraBars.BarManager.SuppressModifierKey?v=24.1" target="_blank" rel="noopener">BarManager.SuppressModifierKey</a> — This global setting specifies the behavior for all

</li>
</ul>
<p> The following example activates MS Word-inspired behavior for a bar item with a combo box. Instead of using the <code data-renderer="hljs" class="csharp" data-control="Code-Inline">Alt</code>+<code data-renderer="hljs" class="csharp"
data-control="Code-Inline">DownArrow</code> combination to open the dropdown, the user simply needs to press <code data-renderer="hljs" class="csharp" data-control="Code-Inline">DownArrow</code>: </p>

<p><strong>ButtonEdit-based Editors</strong></p>
<p> We've optimized the keyboard focus within our ButtonEdit-related controls to ensure that it follows a logical and intuitive sequence. Users can easily tab from the edit box to buttons, navigate through buttons using <code

</h4>
<p> We were in close collaboration with the Microsoft dev team over the last few months, and Microsoft has recently released a Visual Studio 2022 update, which improves form load performance across a number of .NET Core / .NET usage
scenarios. </p>
<p> These performance enhancements are not tied to any DevExpress version because they are implemented at the Visual Studio core level (based on our feedback associated with problematic internal routines). From Microsoft
<a href="https://learn.microsoft.com/en-us/visualstudio/releases/2022/release-notes#performance-improvements-in-windows-forms-out-of-process-designer" target="_blank" rel="noopener">release notes</a>: </p>
<div class="Attention">
<p class="sys-h-align-left"> Through a fruitful collaboration with a key partner, we are thrilled to announce substantial enhancements to the WinForms server process <code data-renderer="hljs" class="csharp"
data-control="Code-Inline">TypeResolutionService</code>. These enhancements have yielded remarkable design time performance improvements, ranging from 30% to an impressive 50% in typical line of business applications. Notably, these
enhancements particularly shine during scenarios that trigger server process restart and designer reload, such as project rebuilds or adjustments in project references. </p>
<p class="sys-h-align-left"> At the heart of these performance improvements lies a new mechanism implemented by our team, prioritizing assemblies crucial for designer load. We encourage you to explore the updated designer and share your
invaluable feedback through <a href="https://developercommunity.visualstudio.com/VisualStudio" target="_blank" rel="noopener">VS Feedback channel</a> so that we can continue improving WinForms designer performance. </p>

<p> You can cut an additional 1-2 seconds from designer startup (if you do not need all DevExpress WinForms components simultaneously on your forms) by using the following smaller packages (like DevExpress.Win.Grid,
DevExpress.Win.TreeList, DevExpress.Win.Charts, etc.) instead of the large <strong>DevExpress.Win.Design</strong> package. </p>

<p> Support for Font Icon Images was first introduced in our WinForms product line (Dec 2023). v24.1 extends this feature to our WPF UI library. </p>
<p> Use the DevExpress WPF Image Picker (integrated within Visual Studio) to assign font icon images to individual UI controls/elements or use our FontIconSource extension to do the same in code. </p> <p><img

the most recent icon font available in the system. For example, the "Segoe Fluent Icons" font is used as the default font if both "Segoe Fluent Icons" and "Segoe MDL2 Assets" fonts are installed. </p>
<p> Use the <a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.FontIconSourceExtension.FontFamily?v=24.1" target="_blank" rel="noopener">FontIconSourceExtension.FontFamily</a> property to specify icon font: </p>

</h4>
<p> A Ribbon-based UI can include dozens of commands across multiple pages. Without prior experience with a given app, users can struggle to locate appropriate actions/commands. To minimize usage friction/learning curve, v24.1 ships with
a new WPF Ribbon Search Box. </p>
<p></p>
<div class="small-image"><img src="/subscriptions/i/24.1/24-1-wpf-ribbon-search.png" srcset="/subscriptions/i/24.1/24-1-wpf-ribbon-search.png 1x, /subscriptions/i/24.1/24-1-wpf-ribbon-search@2x.png 2x"

<p> Specify the <a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.ThemedWindow.SearchItemDisplayMode?v=24.1" target="_blank" rel="noopener">SearchItemDisplayMode</a> property to activate the search box in your WPF app. Our WPF
Ribbon compares the search string to command content (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">BarButtonItem.Content</code>) to generate search results. </p>
<p> You can enable an item's <a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Bars.BarItemSearchSettings.HideFromSearch?v=24.1" target="_blank" rel="noopener">HideFromSearch</a> option to exclude it from search. For more granular
control, use the following events: </p>
<ul>
<li><a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.ThemedWindow.ItemsRequested?v=24.1" target="_blank" rel="noopener">ItemsRequested</a> – Fires when the searchable items list is generated. The event allows you to modify
search results before applying the search criteria (for example, to add additional items based on a condition).</li>
<li><a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.ThemedWindow.ItemFiltering?v=24.1" target="_blank" rel="noopener">ItemFiltering</a> – Fires for each item before it is displayed in search results. The event allows you to

<ul>
<li><a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.ThemedWindow.SearchDelay?v=24.1" target="_blank" rel="noopener">SearchDelay</a> – Specifies the delay in milliseconds between the last text change and the text search.
</li>
<li><a href="https://docs.devexpress.com/WPF/DevExpress.Xpf.Core.ThemedWindow.SearchItemFocusShortcut?v=24.1" target="_blank" rel="noopener">SearchItemFocusShortcut</a> – Specifies the keyboard shortcut used to focus the search box (the

<p> PDF document layers allow you to selectively view or hide specific content sections. The main purpose of layers is to control the visibility of graphics objects rendered in a PDF document across different states (when you view or

<p> We added a <strong>Layers</strong> panel to display all layers contained in a document. This new capability allows you to change layer visibility via the UI. Click the check box next to the layer's name in the new Layers panel to
display/hide a given document layer. Visible layers are highlighted using an “eye” icon; layers that cannot be hidden because of a document configuration do not have a check box next to their name. </p>
<p> With the power of the <strong>PDF Facade API</strong>, you can also access and manage layer visibility at runtime when you preview or print your PDF documents. Call the

<h4 anchor="dxspreadsheet-sort-filter-by-color">
<a name="dxspreadsheet-sort-filter-by-color" class="anchor visible-anchor" href="#dxspreadsheet-sort-filter-by-color">#</a>Sort and Filter by Color
</h4>
<p> The DevExpress WPF Spreadsheet ships with enhanced filter and sort-related capabilities. We added new APIs that can sort and filter workbook data by background and font color. Cell ranges filtered/sorted by cell color can also be
printed and exported to PDF. </p>
<p> Our Sorting APIs include new <a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.Worksheet.Sort.overloads?v=24.1" target="_blank" rel="noopener">Worksheet.Sort</a> method overloads designed to sort a specified
range by font color or fill setting (background color and pattern). </p>
<p> The following code snippet sorts cell values across two cell ranges - the first is sorted by a red font color and the second is sorted by fill settings specified for the first cell in the range: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">spreadsheetControl.LoadDocument(<span class="hljs-string">"sort-filter.xlsx"</span>);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
<span class="hljs-comment">// Sort cell range by font color </span>
worksheet.Sort(worksheet[<span class="hljs-string">"B2:B10"</span>], Color.Red);
<span class="hljs-comment">// Sort cell range by fill color</span>
worksheet.Sort(worksheet[<span class="hljs-string">"D2:D10"</span>], worksheet[<span class="hljs-string">"D2"</span>].Fill);</code></pre>
</div>
</div>
<p> To filter cells by font or background color, you need to apply an auto-filter to the required cell range or table. Once complete, you need to obtain the required column from the <code data-renderer="hljs" class="csharp"
data-control="Code-Inline">AutoFilter.Columns</code> collection and call one of the following methods: </p>
<ul>
<li><a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.AutoFilterColumn.ApplyFillColorFilter(System.Drawing.Color)?v=24.1" target="_blank" rel="noopener">AutoFilterColumn.ApplyFillColorFilter(Color)</a></li>
<li><a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.AutoFilterColumn.ApplyFillFilter(DevExpress.Spreadsheet.Fill)?v=24.1" target="_blank" rel="noopener">AutoFilterColumn.ApplyFillFilter(Fill)</a></li>
<li><a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.AutoFilterColumn.ApplyFontColorFilter(System.Drawing.Color)?v=24.1" target="_blank" rel="noopener">AutoFilterColumn.ApplyFontColorFilter(Color)</a></li>
</ul>
<p> The following code snippet uses these methods for both cell range and table: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">spreadsheetControl.LoadDocument(<span class="hljs-string">"sort-filter.xlsx"</span>);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
<span class="hljs-comment">// Apply an auto-filter to a cell range and filter the first column by font color</span>
worksheet.AutoFilter.Apply(worksheet[<span class="hljs-string">"B1:B10"</span>]);
worksheet.AutoFilter.Columns[<span class="hljs-number">0</span>].ApplyFontColorFilter(Color.Red);
<span class="hljs-comment">// Create a table, apply an auto-filter and filter the first column by fill color</span>
Table table = worksheet.Tables.Add(worksheet[<span class="hljs-string">"B12:B21"</span>], <span class="hljs-literal">true</span>);
table.AutoFilter.Apply();
table.AutoFilter.Columns[<span class="hljs-number">0</span>].ApplyFillColorFilter(Color.Red);</code></pre>
</div>
</div>
<p> In addition, our new APIs allow you to sort data across a filtered range (when auto-filter is enabled) and sort cells by their values/colors simultaneously (using sorting conditions). </p>

<p> To customize Splitter appearance, specify the <a href="https://js.devexpress.com/Documentation/24_1/ApiReference/UI_Components/dxSplitter/Configuration/#separatorSize" target="_blank" rel="noopener">separatorSize</a> property to
modify the size of the handle's shorter side. You can also alter color and icons through CSS. </p>
<p> Enable <a href="https://js.devexpress.com/Documentation/24_1/ApiReference/UI_Components/dxSplitter/Configuration/#allowKeyboardNavigation" target="_blank" rel="noopener">allowKeyboardNavigation</a> in the Splitter component to control
Splitter actions through shortcut keys, mirroring mouse functions. To see the full list of shortcuts, refer to the following help topic:

reduced DevExtreme JS scripts size as follows: </p>
<ul>
<li>We updated the ECMAScript compilation target for DevExtreme JS code. This eliminated the need for complicated syntactic constructions (due to transpiling) for operations supported by
<a href="https://js.devexpress.com/Documentation/Guide/Common/Supported_Browsers/" target="_blank" rel="noopener">all modern browsers</a>.</li>
<li>We ceased storage of time zone data. We switched to an internal browser time zone engine for time zone related operations.</li>

</h4>
<p> Angular <a href="https://angular.io/api/common/http/HttpClientModule" target="_blank" rel="noopener">HttpClientModule</a> is a module that simplifies HTTP requests. It supports request and response interceptors, which allows you to
introduce capabilities such as authentication tokens or logging across all HTTP requests. </p>
<p> Previously, our <a href="https://js.devexpress.com/Documentation/24_1/ApiReference/Data_Layer/DataSource/" target="_blank" rel="noopener">DataSource</a>,
<a href="https://js.devexpress.com/Documentation/24_1/ApiReference/UI_Components/dxFileUploader/" target="_blank" rel="noopener">FileUploader</a>, and
<a href="https://js.devexpress.com/Documentation/24_1/ApiReference/UI_Components/dxMap/" target="_blank" rel="noopener">Map</a> components depended on non-native Angular Ajax requests for server communication. </p>
<p> With v24.1, we transitioned these components from Ajax to the <code data-renderer="hljs" class="csharp" data-control="Code-Inline">HttpClientModule</code>. Simply import our <code data-renderer="hljs" class="csharp"
data-control="Code-Inline">DxHttpModule</code> to activate this new functionality. </p>
<p> In the following example, DataSource utilizes DxHttpModule for request interception. </p>

</h3>
<p><a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_shadow_DOM" target="_blank" rel="noopener">Shadow DOM</a> represents one of three Web Components specifications, complemented by
<a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_templates_and_slots" target="_blank" rel="noopener">HTML templates</a> and
<a href="https://developer.mozilla.org/en-US/docs/Web/API/Web_components/Using_custom_elements" target="_blank" rel="noopener">Custom Elements</a>. </p>
<p> Shadow DOM allows the attachment of a hidden, separate Document Object Model (DOM) to an element, termed the 'Shadow Host'. This hidden DOM, called the 'Shadow DOM', can contain additional nested Shadow Hosts, forming a structure
known as a Shadow Tree. </p>
<p> It's a direct method to create components with isolated CSS and JavaScript. Many everyday web interfaces use Shadow DOM (a feature available in all major browsers). </p>
<p> This release cycle introduces Shadow DOM support in Angular, React, and Vue as a Community Technology Preview (CTP). Accordingly, you can now use DevExtreme components inside the Shadow DOM of custom HTML elements (Web Components).
</p>

<li>Filter Row with Auto-Generated Editors</li>
<li>Total Summaries</li>
<li>Single and Multiple Node Selection</li>

<p> You will notice that the DevExpress Blazor TreeList and Grid UI components look and behave in a similar manner. This is not a coincidence. Our Blazor TreeList and Grid use the same rendering engine and rely upon common
logic/algorithms. Thanks to commonalities between the components, we are in position to add new functionality to both of components simultaneously in future release cycles. </p> <span class="H-Separator"></span>

</h4>
<p> Our Blazor TreeList component can be bound to any traditional data source. Since the TreeList is designed to display information using a tree structure, its data source must meet specific requirements. If a data source contains flat
data, two additional fields are necessary to build the appropriate tree structure: </p>
<ul>
<li>A field that contains a node’s unique identifier. Assign this field to the <a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.DxTreeList.KeyFieldName?v=24.1" target="_blank" rel="noopener">KeyFieldName</a> property.</li>
<li>A field that contains the unique identifier of a node’s parent. Assign this field to the
<a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.DxTreeList.ParentKeyFieldName?v=24.1" target="_blank" rel="noopener">ParentKeyFieldName</a> property.</li>

<p> The DevExpress Blazor TreeList allows you to initially load only root nodes and retrieve node children when a node is expanded for the first time. To switch the component to on demand mode, follow the steps below: </p>
<ul>
<li>Assign root data items to the <a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.DxTreeList.Data?v=24.1" target="_blank" rel="noopener">Data</a> property.</li>
<li>Specify the <a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.DxTreeList.HasChildrenFieldName?v=24.1" target="_blank" rel="noopener">HasChildrenFieldName</a> property.</li>
<li>Handle the <a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.DxTreeList.ChildrenLoadingOnDemand?v=24.1" target="_blank" rel="noopener">ChildrenLoadingOnDemand</a> event. In the event handler, use the
<a href="https://docs.devexpress.com/Blazor/DevExpress.Blazor.TreeListChildrenLoadingEventArgs.Parent?v=24.1" target="_blank" rel="noopener">Parent</a> argument to determine the processed node and assign the node’s children to the

<p> Our new <a href="https://docs.devexpress.com/XtraReports/404883/web-reporting/standalone-parameters-panel?v=24.1" target="_blank" rel="noopener">Report Parameters Panel</a> component automatically generates a layout for report
parameter editors (including associated grouping) based on a report instance supplied from the backend. </p>
<p> This component addresses a variety of usage scenarios, including the need to programmatically create a report and export it or send it by mail - without displaying its print preview to an end-user. Our Standalone Parameters Panel
helps reduce an app’s overall memory footprint because it eliminates the need to generate report images in the background and send them to a client app. </p>

<h4 anchor="reporting-expression-func">
<a name="reporting-expression-func" class="anchor visible-anchor" href="#reporting-expression-func">#</a>New Expression Functions
</h4>
<p> We added the following new expression functions to criteria language syntax used in DevExpress Reports: </p>
<ul>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">PrevRowColumnValue(<span class="hljs-built_in">string</span> columnName)</code> — Allows users to retrieve the value of the previous column/row. The function call
returns the same record if it is the first record in the data source.</li>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">NextRowColumnValue(<span class="hljs-built_in">string</span> columnName)</code> — Allows users to retrieve the value of the next column/row. The function call
returns the same record if it is the latest record in the data source.</li>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">GroupIndex(<span class="hljs-built_in">int</span> level)</code> — Allows users to retrieve the current group index.</li>
<li><code data-renderer="hljs" class="csharp" data-control="Code-Inline">CurrentRowIndexInGroup()</code> — Allows users to retrieve the current row index within a group.</li>
</ul>
<p> Functions are applicable to report control properties whose values can be set via expression binding. They are especially useful when you need to hide first or last records within a group, or highlight these records (i.e., modify
appearance properties like Font, BackColor, etc.). Obtaining the group index or the row index within a group is helpful when you need to display group numbering in the group header or record numbering within the group itself. The
introduction of <code data-renderer="hljs" class="csharp" data-control="Code-Inline">PrevRowColumnValue</code> and <code data-renderer="hljs" class="csharp" data-control="Code-Inline">NextRowColumnValue</code> functions also simplifies
migration from Microsoft SSRS and Crystal Reports, where their counterparts exist. </p>
<p> The following example generates a report with a multi-level numbered list. To achieve this report layout, report controls use <code data-renderer="hljs" class="csharp" data-control="Code-Inline">GroupIndex</code> and <code
data-renderer="hljs" class="csharp" data-control="Code-Inline">CurrentRowIndexInGroup</code> functions within data binding expressions (to return group and row indexes). </p>

<p> With v24.1, DevExpress Reports and BI Dashboard will utilize functionality from the <code data-renderer="hljs" class="csharp" data-control="Code-Inline">System.Text.Json</code> assembly/NuGet package (by default). This change was

<p> You can now set up cascading parameters to filter the data source or items in a dashboard. The list of values of a dependent parameter now refreshes automatically when you change the value of the parent parameter. When using two
parameters, the parent parameter is used to filter the data source for the dependent parameter with dynamic list settings. The following image illustrates cascading parameters where Products parameter values are filtered by the selected

<h4 anchor="web-dashboard-cache-api">
<a name="web-dashboard-cache-api" class="anchor visible-anchor" href="#web-dashboard-cache-api">#</a>Cache Management API
</h4>
<p> This update allows you to tailor our built-in BI Dashboard caching engine. Customers encountered several scenarios where our built-in cache needed to be disabled, prompting us to introduce the following API. </p>
<p> You can now use the <a href="https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.ASPxDashboard.DataSourceCacheEnabled?v=24.1" target="_blank" rel="noopener">ASPxDashboard.DataSourceCacheEnabled</a> property for Web Forms (or
the <a href="https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.DashboardConfigurator.DataSourceCacheEnabled?v=24.1" target="_blank" rel="noopener">DashboardConfigurator.DataSourceCacheEnabled</a> property for other web
platforms) to disable caching entirely. This forces the DevExpress Dashboard to load the most relevant data whenever a user accesses and views a dashboard. </p>
<p> By default, whenever a dashboard parameter value changes, a new data source instance is created and stored in the cache. This impacts memory usage, especially when a parameter doesn't affect data source filtering. As such, we added
the <a href="https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.ASPxDashboard.DataSourceCacheKeyCreated?v=24.1" target="_blank" rel="noopener">ASPxDashboard.DataSourceCacheKeyCreated</a>/
<a href="https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.DashboardConfigurator.DataSourceCacheKeyCreated?v=24.1" target="_blank" rel="noopener">DashboardConfigurator.DataSourceCacheKeyCreated</a> event to prevent the
creation of new cache records based on parameter values/available event arguments. For instance, consider the following: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
<span class="hljs-keyword">if</span>(e.Key.DashboardId == <span class="hljs-string">"MyDashboard"</span>)
e.Key.Parameters.Clear();
};</code></pre>
</div>
</div>
<p> In this scenario, altering a parameter value updates dashboard item data, while reusing the existing data source from the cache without additional fill requests. </p>
<p> Furthermore, you can utilize this event to update a specific data source when any interaction with the dashboard takes place: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
<span class="hljs-keyword">if</span>(e.Key.DataSourceId == <span class="hljs-string">"dsSales"</span>)
e.InvalidateCacheRecord();
};</code></pre>
</div>
</div>
<p> Another use case involves increasing cache key granularity by including groups of users or the users themselves in the cache key. You can utilize the new
<a href="https://docs.devexpress.com/Dashboard/DevExpress.DashboardCommon.IDataSourceCacheKey.CustomData?v=24.1" target="_blank" rel="noopener">IDataSourceCacheKey.CustomData</a> property for this purpose. The primary advantage of this
strategy is that the key is solely used for creating/retrieving records from the cache and is never exposed on the client side, thus maintaining the security aspect of the implementation: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">
<pre><code data-renderer="hljs" class="csharp">DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
e.Key.CustomData.Add(<span class="hljs-string">"UserId"</span>, CurrentUser.UserId);
};</code></pre>

<p> To filter cells by font or background color, you need to apply an auto-filter to the required cell range or table. Once complete, you need to obtain the required column from the <code data-control="Code" class="Code Inline"><code
class=" language-cs">AutoFilter<span class="token punctuation">.</span>Columns</code></code> collection and call one of the following methods: </p>
<ul>
<li><a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Spreadsheet.AutoFilterColumn.ApplyFillColorFilter(System.Drawing.Color)?v=24.1" target="_blank" rel="noopener">AutoFilterColumn.ApplyFillColorFilter(Color)</a></li>

</ul>
<p> The following code snippet uses these methods for both cell range and table: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>
</ul>
<div class="CodeContainer Active">

<span class="hljs-comment">// Apply an auto-filter to a cell range and filter the first column by font color</span>

table.AutoFilter.Apply();
table.AutoFilter.Columns[<span class="hljs-number">0</span>].ApplyFillColorFilter(Color.Red);</code></pre>
</div>
</div>
<p> In addition, our new APIs allow you to sort data across a filtered range (when auto-filter is enabled) and sort cells by their values/colors simultaneously (using sorting conditions). </p>

<p> v24.1 includes an enhanced PDF Facade API and new APIs designed to manage Optional Content (Layers) visibility in code. </p>
<p><strong>Note</strong>: A PDF document only stores a default Optional Content configuration. This means that Layer visibility is not preserved when you save the document. Visibility settings are only applicable when you preview the
document in the PDF Viewer component or print the document/export it to an image. </p>
<p> The new API is available via the <a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Pdf.PdfDocumentFacade.OptionalContentVisibility?v=24.1" target="_blank" rel="noopener">PdfDocumentFacade.OptionalContentVisibility</a>
property. Access Optional Content groups using the <code data-control="Code" class="Code Inline"><code class=" language-cs">PdfOptionalContentVisibility<span class="token punctuation">.</span>Groups</code></code> collection. To change
group visibility, modify the <a href="https://docs.devexpress.com/OfficeFileAPI/DevExpress.Pdf.PdfOptionalContentGroupVisibility.Visible?v=24.1" target="_blank" rel="noopener">PdfOptionalContentGroupVisibility.Visible</a> property

<p> XAF WinForms apps include an Object Model dialog. With it, end-users can search, tick or untick data model fields (including sub-fields and collections), which are not yet displayed in the grid or layout control (as part of the Column
Chooser or Customization Form). </p>
<p> Much like Microsoft Office apps, this capability allows users to fully customize list and detail forms (based on the structure of a data model). Again, this is helpful when developers need to address changes to business requirements
without redeployment. For more information, refer to
<a href="https://docs.devexpress.com/eXpressAppFramework/404353/ui-construction/views/layout/view-items-layout-customization-blazor?v=24.1" target="_blank" rel="noopener">Runtime Layout Customization in ASP.NET Core Blazor Applications</a>.
</p>
<p> XAF Blazor v24.1 provides a similar experience for both ListView

This feature removes the need for many UI customizations in the design-time Model Editor (inside Visual Studio) - something many of you love in XAF WinForms UI. Of course, you can also disable these runtime capabilities for end-users.

</h4>
<p> Tabbed MDI is a multiple document interface (MDI) UI metaphor found in many modern applications (including your favorite Web browser or Microsoft Outlook Web). It is a robust interface that maximizes document screen real estate,
especially when working with multiple documents, email messages, etc. </p>
<p><a href="https://docs.devexpress.com/eXpressAppFramework/DevExpress.ExpressApp.UIType?v=24.1" target="_blank" rel="noopener">Tabbed MDI</a> is enabled in XAF WinForms apps by default, and XAF Blazor provides a similar user experience
in v24.1. You can also customize Tabbed MDI in the Model Editor as follows: </p>
<ul>
<li> Restore previously opened tabs between application runs (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">RestoreTabbedMdiLayout</code> = True by default). </li>
<li> Refresh View data source on tab focus (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">RefreshViewOnTabFocus</code> = False by default) </li>
<li> Display or hide tab images (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">ShowTabImage</code> = True by default) </li>
</ul>
<p> In addition, you can access the underlying tab control in code and configure it as needed using a Controller (in the "SolutionName.Blazor" project). For instance, you can load tabs on demand or simultaneously: </p>
<div data-control="Code" class="Code CodeNew">
<ul>
<li class="Active">C#</li>

<p> In v24.1, we reduced boilerplate code for many popular UI customization scenarios: </p>

which were cumbersome or noisy. </p>
<p> With this release, the amount of required code is much less (like its XAF WinForms counterpart). Our built-in <code data-renderer="hljs" class="csharp" data-control="Code-Inline">ComponentModel</code> classes now handle component

</ul>
<p> XAF Blazor also ships with its own set of UI components/elements (like property editors and action containers). In v24.1, we extended accessibility support and improved keyboard support for all XAF Blazor UI elements (~20% of
scenarios). XAF accessibility support will also level up automatically as soon as we enhance accessibility in DevExpress Blazor UI components throughout 2024. </p>
<p> Our Blazor Grid's keyboard navigation option also officially ships and is enabled by default in XAF Blazor. </p>

<a name="xaf-sso-support" class="anchor visible-anchor" href="#xaf-sso-support">#</a>Single Sign-On Support
</h4>
<p> In v24.1, XAF Blazor and WinForms .NET 6+ apps support Single Sign-On (SSO) natively. Today, modern business apps are integrated with many external systems within organizations. For instance, if an organization uses Microsoft 365, XAF
apps are often available at <a href="https://myapps.microsoft.com/" target="_blank" rel="noopener">https://myapps.microsoft.com/</a> among many other apps within this organization. Since XAF Blazor and WinForms .NET 6+ apps (both XPO
and EF Core-based) support Microsoft Entra ID and other
<a href="https://docs.devexpress.com/eXpressAppFramework/404648/data-security-and-safety/security-system/authentication/oauth-and-custom-authentication" target="_blank" rel="noopener">OAuth2 providers</a>, organizations want/prefer XAF
apps to share the same login details or authentication cookies with existing systems/services such as
<a href="https://www.microsoft.com/en-us/security/business/identity-access/microsoft-entra-single-sign-on" target="_blank" rel="noopener">Microsoft Entra SSO</a>. </p>
<p> Said differently, organizations require the following: when a user is already authenticated within the organization (for instance, using Microsoft 365), XAF apps must seamlessly work with SSO. Previously, XAF developers had to
implement custom solutions to modify XAF’s login form and authentication behavior to support SSO. </p>
<p> Important SSO scenarios include, but are not limited to the following: </p>
<ul>
<li>
<p> If a user is NOT logged in within the organization, then XAF apps display a standard OAuth2/SSO provider logon form (just like Teams, Word or Outlook normally does for Microsoft 365). If a user was forced to sign out by
administrators, then XAF apps should display the standard logon form as well. </p>
</li>
<li>
<p> If a user is logged in within the organization (it can be another non-XAF app), then no XAF login form is displayed for the user and focus moves directly to the XAF app UI (by a link from an organization's `Apps dashboard` or via
other methods). The logon procedure in an XAF app proceeds automatically behind the scenes (via API calls). XAF users should NOT be forced to explicitly press the “Login with Microsoft” in this instance, because SSO will "just work"
as expected. </p>
</li>
</ul>

<p> In addition, it is now possible to call the new

method from within your BaseObject descendants to bypass security checks for certain protected properties in your internal application logic (custom base classes are also supported). </p>
<p> This capability is especially valuable to XAF developers when you wish to set service properties like CreatedBy, ModifiedBy, CreatedOn, UpdatedOn, etc. - our Audit Trail and Model Difference modules operate using a similar mechanism.
The <code data-renderer="hljs" class="csharp" data-control="Code-Inline">SetPropertyValueWithBypassSecurity</code> method can freely set protected properties on behalf of a restricted/regular user in code much like an application
administrator - without having to know admin credentials (like impersonation for service tasks). </p>

<p> The <code data-renderer="hljs" class="csharp" data-control="Code-Inline">SetPropertyValueWithBypassSecurity</code> also includes certain limitations like calling this method is only supported from inside <code data-renderer="hljs"

popular use-cases. </p>

</h4>
<p> In v24.1, XAF WinForms apps (.NET 6+) with Middle Tier Security natively supports <a href="https://docs.devexpress.com/eXpressAppFramework/404436/multitenancy" target="_blank" rel="noopener">Multi-Tenancy</a> and

ID or Google). Our <a href="https://github.com/DevExpress-Examples/xaf-create-multitenant-application/tree/24.1.2%2B" target="_blank" rel="noopener">Outlook Inspired Demo</a> now also uses Middle Tier Security with the Multi-Tenancy
module. </p>

topic, Windows desktop apps can better meet enterprise security standards with our Middle Tier application server. With our solution, EF Core or XPO developers can retain their standard DbContext or Session and initiate remote
connections to a data store from any .NET client (like XAF WinForms or non-XAF apps). This capability is critical within certain environments/business apps (those that cannot maintain direct database connections because of security
considerations). </p>
<p> Non-XAF EF Core or XPO developers can benefit from our Middle Tier application server and preserve DbContext or Session with their entity data model
(<a href="https://docs.devexpress.com/eXpressAppFramework/404398/data-security-and-safety/security-system/security-tiers/middle-tier-security-ef-core/connect-to-the-efcore-middle-tier-service-from-non-xaf-applications" target="_blank" rel="noopener">learn more</a>).
<strong>This is especially critical for many desktop .NET developers (WinForms, WPF, WinUI, etc.), who are now required to meet higher security standards</strong>. In a nutshell, these developers need to either retrofit/modernize their
"fat clients" for Windows (#1) or redo everything from scratch using modern Web technologies and Cloud services (#2). Our Middle Tier Security allows you to choose the "easier" and potentially more reliable route (#1), and to "replace"
direct database connections with middleware. Review the following code snippet for more information in this regard: </p>

<p> In v24.1, the DevExpress VCL Ribbon (and other UI controls) allow you to use a single image list for large and small SVG icons. With this capability you can simply specify a small SVG icon and we will scale it up automatically (for
instance, in places where the control needs a large icon in the Ribbon). This will improve overall usability and should reduce time spent/maintenance in half. </p>
<p> Based on our roadmap survey votes, we made it possible for customers to use both old and new icon assignment strategies using

<a href="https://docs.devexpress.com/VCL/405004/ExpressCrossPlatformLibrary/accessibility-support?v=24.1" target="_blank" rel="noopener">partial accessibility support</a> (powered by Microsoft Active Accessibility or
<a href="https://learn.microsoft.com/en-us/windows/win32/winauto/microsoft-active-accessibility" target="_blank" rel="noopener">MSAA</a>). We initially hoped to use MSAA to support remaining VCL controls, but research showed that it is
not technically feasible. It turned out that this COM-based technology is outdated for modern accessibility requirements and highly interactive UI controls like ours. </p>
<p> Accordingly, we built a new engine for ongoing accessibility-related enhancements (it is powered by Microsoft UI Automation or
<a href="https://docs.microsoft.com/en-us/dotnet/framework/ui-automation/ui-automation-overview" target="_blank" rel="noopener">UIA</a> - used in DevExpress WinForms and WPF products). UIA gave us much more flexibility and allowed to
introduce the following accessibility-related v24.1 features: </p>
<ul>
<li>UIA-powered controls now include Automation options like Name, Description, etc.</li>
<li>UIA-powered controls now include specialized events to customize Automation options at runtime.</li>
<li>UIA-powered controls currently include Button, Check Box, Radio Button, Group Box, Panel, Text Editor, Button Editor, and Label.</li>

<li>Form layout manager (including layout groups, tabs, etc.)</li>

<a name="vcl-accent-insensitive-operation" class="anchor visible-anchor" href="#vcl-accent-insensitive-operation">#</a>Accent-Insensitive Operation Support for Data-Aware Controls
</h4>
<p> With v24.1, you can configure how various diacritic glyphs in letters (umlauts, grave, acute, and other accents) are treated. For instance, if you type "Joao" in a search box, Data Grid filtering results will include data records with
both "João" and "Joao". For more information, read the following quote from <a href="https://en.wikipedia.org/wiki/Diacritic" target="_blank" rel="noopener">Wikipedia</a>: </p>
<div class="Attention">
<p class="sys-h-align-left"> A <strong>diacritic</strong> (also diacritical mark, diacritical point, diacritical sign, or accent) is a glyph added to a letter or to a basic glyph. The term derives from the Ancient Greek διακριτικός
(diakritikós, "distinguishing"), from διακρίνω (diakrī́nō, "to distinguish"). The word diacritic is a noun, though it is sometimes used in an attributive sense, whereas diacritical is only an adjective. Some diacritics, such as the
acute ⟨á⟩, grave ⟨à⟩, and circumflex ⟨â⟩ (all shown above an 'a'), are often called accents. Diacritics may appear above or below a letter or in some other position such as within the letter or between two letters. </p>
</div>
<p> You can enable or configure accent-insensitive operations globally using the <a href="https://docs.devexpress.com/VCL/dxCore.TdxDiacriticStringOptions?v=24.1" target="_blank" rel="noopener">TdxDiacriticStringOptions</a> class: </p>
<ul>
<li><a href="https://docs.devexpress.com/VCL/dxCore.TdxDiacriticStringOptions.ComparisonMode?v=24.1" target="_blank" rel="noopener">ComparisonMode</a>: allows you to switch between comparison modes (Auto, Sensitive, Insensitive). By
default (Sensitive), we do not ignore accents. Insensitive mode can be of value for global organizations with users from different countries/data (for instance, names of employees or goods can be in different languages). </li>
<li><a href="https://docs.devexpress.com/VCL/dxCore.TdxDiacriticStringOptions.NormalizationMode?v=24.1" target="_blank" rel="noopener">NormalizationMode</a>: specifies the string normalization algorithm (Fast, System) used for string
comparison in diacritic-insensitive mode. The default algorithm (Fast) works up to 3 times faster compared to the operating system-dependent algorithm (System). </li>
</ul>
<p><strong>Note</strong>: <code data-renderer="hljs" class="csharp" data-control="Code-Inline">TdxDiacriticStringOptions</code> does not work in Server Mode – use database collation options instead. </p>
<p> Impacted text-comparison operations and control features include: </p>
<ul>
<li>Sorting</li>
<li>Grouping</li>
<li>Incremental search</li>
<li>Auto-filter row</li>
<li>Find panel, etc.</li>
</ul>
<p> This behavior expands to the following controls: </p>
<ul>
<li>Navigation control</li>
<li>Ribbon and standard toolbars</li>
<li>Lookup editors</li>
<li>Data grid</li>
<li>Pivot grid</li>

<li>Crop and straighten</li>
<li>Adjust brightness, contrast and saturation</li>
<li>Mirror</li>
<li>Rotate, etc.</li>
</ul>

</h4>
<p> In v24.1, our image controls (<code data-renderer="hljs" class="csharp" data-control="Code-Inline">TcxImage</code> and <code data-renderer="hljs" class="csharp" data-control="Code-Inline">TcxDbImage</code>) read and interpret EXIF
metadata from images and modify the image display accordingly. For instance, our image controls automatically rotate the image based on orientation metadata (unlike the standard TImage control and certain image viewers). </p>
<p> Impacted image-based scenarios (where rotation will take place) include: </p>
<ul>
<li>Data Grid cells</li>
<li>TreeList cells</li>
<li>Vertical and Property Grid cells</li>
</ul>
<p> Previously, this required a complex custom solution with a manual call of the Rotate method. Customers who implemented custom solutions on their own (for instance, image rotation in the grid or standalone image editors), can disable
this default behavior using a static feature toggle. The
<a href="https://docs.devexpress.com/VCL/dxGDIPlusClasses.TdxGPImage.DefaultImageExifAutoRotation?v=24.1" target="_blank" rel="noopener">TdxGPImage.DefaultImageExifAutoRotation</a> class property value defines if the image editor
rotates an image based on EXIF metadata. </p> <span class="H-Separator"></span>

<a name="vcl-field-name-based-expressions" class="anchor visible-anchor" href="#vcl-field-name-based-expressions">#</a>Field Name-Based Expressions for Data-Aware Controls
</h4>
<p> With v24.1, you can use <code data-renderer="hljs" class="csharp" data-control="Code-Inline">{FieldName}</code> in
<a href="https://docs.devexpress.com/VCL/168035/ExpressSpreadSheet/concepts/formula-expressions/built-in-operators-and-functions" target="_blank" rel="noopener">formula expressions</a> in conditional formatting rules to refer to a field
by underlying name instead of a display name. Previously, you could only use a display name/caption or an index. This capability will help you create formulas for conditional formatting rules. </p>
<p> This is helpful in VCL apps that support multiple languages or other scenarios where you cannot rely on a field caption (due to its dynamic nature such as translation to another language). </p>

CROSS-PLATFORM ENHANCEMENTS V24.1
ACCESSIBILITY ENHANCEMENTS
Accessibility support remains a top engineering priority. Accordingly, we
enhanced keyboard navigation/screen reader support, extended automation
capabilities and other accessibility-related features to ensure better
compliance with standards outlined in WCAG.
This release includes enhancements across most of our desktop and web component
suites:
* WinForms Controls
* WPF Controls
* DevExtreme JavaScript Components
* Blazor UI Components
* ASP.NET Core Controls
* .NET Reporting
* XAF - Cross-Platform .NET App UI (Blazor)
* VCL Controls
SUPPORT OF NEW .NET DATEONLY AND TIMEONLY TYPES ACROSS UI PLATFORMS
We now support DateOnly and TimeOnly types in data-aware UI controls (such as
Data Grid, Tree List, Date and Time Editors) for the following UI platforms in
.NET Core / .NET 6+ apps.
* WinForms Controls
* WPF Controls
* Blazor UI Components
* XAF - Cross-Platform .NET App UI (Blazor)
* Please review the links above for additional information (supported features
vary across UI platforms and controls).
Thanks to changes at core levels (our DevExpress.Data and DevExtreme.AspNet.Data
libraries), we now support these data types for our client/in-memory and server
mode data sources (both of which are used by multiple UI controls listed above):
* EntityServerModeSource / EntityInstantFeedbackSource
* LinqServerModeSource / LinqInstantFeedbackSource
* GridDevExtremeDataSource (for ASP.NET Core / DevExtreme and Blazor-based
controls)
You can sort, group, and filter data (and other capabilities) against DateOnly
and TimeOnly values. We also extended our criteria language as follows:
* You can use date/time-related functions (such as AddHours, GetDays,
DateDiffDays, etc.) in filter expressions and unbound columns.
* You can now wrap DateOnly/TimeOnly constants in '#' and '!' for string filter
expressions:
[OrderDate] >= #!2018-03-22!# && [OrderTime] >= #!18:22:00!#
Due to the following Microsoft-related breaking change these new data types are
of special importance to EF Core 8 developers: SQL Server date and time now
scaffold to .NET DateOnly and TimeOnly. DevExpress customers will benefit from
this new functionality even if NOT using EF Core 8 for data access – it is just
important that the underlying database or IQueryable provider supports the new
data types (like Microsoft SQL Server with EF Core 8). Here is a quote from
Microsoft about the general value for .NET developers:
DateOnly and TimeOnly were introduced in .NET 6.0, and are a perfect match for
mapping the database date and time types. DateTime notably contains a time
component that goes unused and can cause confusion when mapping it to date, and
TimeSpan represents a time interval - possibly including days - rather than a
time of day at which an event occurs. Using the new types prevents bugs and
confusion, and provides clarity of intent.
Note: Microsoft and third-party package vendors did not backport DateOnly and
TimeOnly types on .NET Framework. Additionally, we do not officially support
this feature for .NET Framework and OData/XPO data sources within both
frameworks. We encourage you to migrate to .NET 6+ to benefit from the new data
types. Technically, we share parts of our codebase between .NET Framework and
.NET, so do not be confused that our DevExpress.Data library for .NET Framework
includes our own "shim" DateOnly and TimeOnly types. If you experience any
conflicts with third-party compatibility packages (like one or two for
unofficial support), we recommend that you remove these packages.
.NET AND .NET FRAMEWORK — MIGRATION FROM NEWTONSOFT.JSON TO SYSTEM.TEXT.JSON
In our v24.1 release cycle, the following DevExpress products will use
Microsoft’s System.Text.Json instead of Newtonsoft.Json for JSON
serialization-related tasks in runtime code:
* Data Access Library: BI Dashboards (DashboardJsonDataSource) and Reporting
(JsonDataSource) for .NET 6+ WinForms, WPF, Blazor, ASP.NET Core apps (.NET
Framework apps will continue to use the Newtonsoft.Json library. We expect to
switch to System.Text.Json in our v24.2 release cycle).
Breaking Change
* Data Access Library for .NET 6+ and .NET Framework DevExtreme, Blazor and
ASP.NET Core apps (a System.Text.Json-compatible version of
DevExtreme.AspNet.Data v4.0.0+ is now available).
Breaking Change
* Backend Web API Service for .NET 6+ non-XAF apps (DevExtreme, Blazor, .NET
MAUI, etc.) and XAF apps.
Breaking Change
* Maps in .NET 6+ WinForms in WPF, Blazor, ASP.NET Core apps (.NET Framework
apps will continue to use the Newtonsoft.Json library. We expect to switch to
System.Text.Json in our v24.2 release cycle).
Breaking Change
* Blazor Rich Text Editor (no Breaking Changes).
Our design-time code (wizards, designers and tools) may still continue to use
Newtonsoft.Json, because of dependencies within Visual Studio (some design-time
services still rely on Newtonsoft.Json, but we believe this will change in the
future). Remaining .NET Framework products that currently rely on the
Newtonsoft.Json library, will likely switch to System.Text.Json in the future.
Here we rely on the minimally supported .NET Framework version for DevExpress
products, which will likely change from 4.5.2 to 4.6.2 in v24.2.

DATEONLY & TIMEONLY TYPE SUPPORT
DevExpress WinForms data-aware UI controls (such as our Data Grid and TreeList)
and the Date Editor now support DateOnly and TimeOnly data types (in .NET
applications). These data types offer the following advantages (versus the
traditional DateTime type): usage clarity, improved database compatibility, less
space during serialization, and the ability to mitigate potential
errors/inconsistencies related to different time zones.
Built-in DateOnly/TimeOnly support extends to:
* UI Elements Related to Data Filtering (Column Filter Popup, Filter Editor,
Expression Editor, Automatic Filter Row)
* Conditional Formatting Rules
* Data Summaries
* Data Grouping
* Unbound Columns
* Masks
* Search
* Criteria Operators
* C#
gridView.ActiveFilterString = "[Date]=#!2022-02-01!#";
We also added DateOnly/TimeOnly type support within our server-based data
sources:
* EntityServerModeSource / EntityInstantFeedbackSource
* LinqServerModeSource / LinqInstantFeedbackSource
You can sort, group, and filter data in server mode sources against DateOnly and
TimeOnly values. And yes, you can use date/time-related functions (such as
AddHours(), GetDays(), DateDiffDays()) in filter expressions and unbound
columns.
DATA GRID
#MERGED CELL EDITING
As its name implies, users can now simultaneously edit all cells in a merged
range or modify separate cells (in GridView and BandedGridView) as needs
dictate. Use the new MergedCellEditMode property to activate this feature and
specify how users edit merged cell data.
Options include:
* VisibleCells – Edits data cells in a merged range.
* FocusedCell – Edits data cells in a merged range for the focused row.
* Disabled
* C#
using DevExpress.XtraGrid.Views.Grid;
// Allows users to edit data cells in a merged range.
gridView1.OptionsView.MergedCellEditMode = MergedCellEditMode.VisibleCells;
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
#DISPLAY CUSTOM UI ELEMENTS IN THE FIND PANEL
v24.1 includes new APIs to display predefined and/or custom UI controls in the
Find Panel. With this new option, you can build fully customizable/personalized
interfaces when using the DevExpress Find Panel.
Use view.FilterPanelItems to introduce custom Find Panel UI elements in your
WinForms app:
* AddControl — Displays the specified UI control.
* AddButton — Displays a button.
* AddCheckButton — Displays a checked button.
* AutoHeight — Updates Find Panel height to match UI elements.
* RemoveItem / RemoveItems – Removes the specified UI element(s) from the Find
Panel.
* C#
// This code snippet comes from the Find Panel module in our WinForms Data Grid demo (v24.1).
CheckButton showCustomButton = null;
void ceShowCustomButton_CheckedChanged(object sender, EventArgs e) {
CheckEdit customButton = sender as CheckEdit;
if(customButton.Checked) {
showCustomButton = view.FindPanelItems.AddCheckButton(customButtonName, null, view.OptionsFind.Behavior != FindPanelBehavior.Search,
(button, args) => {
CheckButton checkButton = button as CheckButton;
view.OptionsFind.Behavior = checkButton.Checked ? FindPanelBehavior.Filter : FindPanelBehavior.Search;
checkButton.ToolTip = "Find Panel Mode";
icbFindPanelBehavior.EditValue = view.OptionsFind.Behavior;
});
showCustomButton.ImageOptions.ImageUri.Uri = "Filter;Size16x16;Svg";
}
else {
showCustomButton = null;
view.FindPanelItems.RemoveItem(customButtonName);
}
icbFindPanelBehavior.Enabled = showCustomButton == null;
}
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
#HIDE SPECIFIC FILTERS FROM EXCEL-INSPIRED FILTER DROPDOWN
The WinForms Data Grid control exposes a ShowFilterPopupExcel event and allows
you to hide specific filter options from "Filters" and "Values" tabs of our
Excel-style Filter Dropdown. v24.1 adds a e.HideFilter(filterType) method to
event arguments for advanced customization of the filter menu. Use this method
to hide unnecessary filter operators from the "Filters" tab.
We also introduced this feature in our WinForms TreeList control.
* C#
void gridView1_ShowFilterPopupExcel(object sender, DevExpress.XtraGrid.Views.Grid.FilterPopupExcelEventArgs e) {
if (e.Column.FieldName == "UnitPrice") {
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.BelowAverage);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.Between);
e.HideFilter(DevExpress.Utils.Filtering.Internal.CustomUIFilterType.BottomN);
// ...
}
}
#DISPLAY A CUSTOM DEVEXPRESS POPUP MENU
We've made it easier to display the DevExpress PopupMenu for individual Data
Grid UI elements.
In previous versions, you had to customize the built-in menu (add/remove menu
items) within the control's PopupMenuShowing event. With v24.1, you can display
a custom menu (created and customized at design time or runtime) using the new
e.ShowCustomMenu method:
* C#
void gridView1_PopupMenuShowing(object sender, PopupMenuShowingEventArgs e) {
if (e.MenuType == GridMenuType.Column) {
popupMenu_Column.Tag = e.HitInfo;
popupMenu_Column.MenuCaption = $"{e.HitInfo.Column}";
e.ShowCustomMenu(popupMenu_Column);
}
}
API enhancements extend to: DevExpress TreeList, Vertical Grid (Property Grid),
and Pivot Grid.
How to: Implement a Custom Menu in the DevExpress WinForms Data Grid
#EXPORT CELL IMAGES TO EXCEL
The WinForms Data Grid control now exports images (raster and SVG) displayed
within cells of bound and unbound columns to XLSX in data-aware export mode.
Cell images are exported as a Byte[] array. To activate this feature, set the
AllowCellImages property to DefaultBoolean.True.
* C#
void btnExport_Click(object sender, EventArgs e) {
DevExpress.XtraPrinting.XlsxExportOptionsEx options = new DevExpress.XtraPrinting.XlsxExportOptionsEx();
options.AllowCellImages = DevExpress.Utils.DefaultBoolean.True;
advBandedGridView1.ExportToXlsx("grid_export.xlsx", options);
}
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
You can customize cell images or replace values with images (based on export
conditions) before the Grid Control generates the output document. Handle the
CustomizeCell event as follows:
* C#
void Options_CustomizeCell(DevExpress.Export.CustomizeCellEventArgs e) {
if(e.ColumnFieldName == "Photo" && e.Value == null) {
e.Value = XtraEditors.Controls.ByteImageConverter.ToByteArray(imageCollection1.Images["car"]);
e.Handled = true;
}
}
#CALCULATE THE BEST SIZE
Designed to address common layout-related dev tasks, the new
CalcBestSize(maxSize, checkScrollInfo) method calculates the maximum allowable
size of the Grid Control (to display as many data rows and columns as possible).
#CUSTOM TILE PAINTING FOR THE DEVEXPRESS TILEVIEW (KANBAN)
You can now customize tile appearance by handling the new
TileView.CustomDrawTile event. With its comprehensive event arguments (APIs),
you can easily change border shape and color or draw custom UI elements to
address specific design requirements/user preferences.
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
And yes, you can render HTML and CSS templates inside tiles as needs dictate:
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
#DISPLAY TOOLTIPS FOR TRIMMED CONDITIONAL FORMATTING RULES
If formatting rule name is larger than the width of the cell, the rule will
appear in a tooltip when you hover over the cell:
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
#ANNOTATE CONDITIONAL FORMATTING RULES
With this option, you and your end-users can include descriptive text for
conditional formatting rules, offering insights into the purpose and logic
behind each rule. Implementing text descriptions for conditional formatting
rules is simple and intuitive. Users can add explanations directly in the
Formatting Rule Editor, ensuring that context is available each time they view
or change rules.
To enable this feature, set the OptionsView.AllowFormatRuleDescription property
to true.
Note: we also introduced this feature in our WinForms TreeList, VerticalGrid,
and PivotGrid controls.
TREELIST
#EXPAND NODES ON SEARCH
With this new feature, users can effortlessly locate specific TreeList nodes,
even if they are collapsed within a complex hierarchy. When users initiate a
search within the DevExpress TreeList, the TreeList automatically expands
relevant nodes to display search results (in previous versions, you could only
search through expanded nodes).
Use the TreeList's OptionsFind.ExpandNodesOnSearch setting to enable/disable the
"Expand Nodes on Search" feature.
Run Demo
To execute this demo, you must first
install the DevExpress WinForms product library .
#IMPROVED PERFORMANCE FOR LARGE DATA SOURCES
We improved WinFroms TreeList performance to better address usage scenarios when
large data updates are made to the underlying data source.
The following internal test results illustrate performance improvements:
#AUTO-FILTER ROW FOCUS RETENTION
This addition to our WinForms TreeList control ensures that user focus remains
unaffected when using the Auto-Filter Row, even during data updates.
In previous versions, the TreeList automatically closed the active editor in the
Auto-Filter Row when updating data. In v24.1, the editor remains active (users
can edit filter criteria during data updates).
ACCORDION
#DISPLAY ITEM CAPTIONS IN A MINIMIZED STATE
We added a new CaptionShowMode property to control how the item caption is
displayed when the Accordion control is minimized/collapsed.
Options include:
* Below Image
* Above Image
* None
The new CaptionImageIndent property specifies the indent between the image and
caption.
#CONFIGURABLE ITEM INDENTS
With this new option, you can introduce fully personalized side navigation
logic. We added the ChildIndentStartLevel property. This property specifies the
hierarchy level that starts the indentation of child elements.
We also implemented a new QueryElementIndent event that allows you to adjust the
indent for specific accordion items based on design preferences/requirements.
RIBBON & BARS
#PAGE KEY TIPS
We added a new ShowPageKeyTipsMode property. Use this property to configure the
display of page key tips within the Ribbon UI. This enhancement allows users -
who prefer to use keyboard shortcuts instead of mouse input - to quickly
navigate through different Ribbon sections and access specific commands (without
unnecessary keystrokes).
Options include:
* Hide - Hides key tips for all Ribbon pages.
* ShowOnMultiplePages - Displays key tips only if the Ribbon UI displays
multiple pages.
* Show (Default) - Displays key tips for all visible Ribbon pages and for the
selected page (even if the selected page is hidden).
#BARCHECKITEM – CHECKED-STATE IMAGE
You can now specify different images (bitmap or SVG) for checked and unchecked
states of checkbox items (BarCheckItem).
New APIs include:
* CheckedImage / CheckedImageIndex / CheckImageKey
* CheckedLargeImage / CheckedLargeImageIndex / CheckLargeImageKey
* CheckedSVGImage
#PRESS ENTER TO EXECUTE A COMMAND
We extended available user interactions within the command search box. Users can
execute commands without the need for additional clicks or interactions. Handle
the new SearchMenuEnterPressed event to execute a command based on freely
written text or the first found command instantly when the user performs a
search and presses the Enter key.
#MANAGE AND DISPLAY RELEVANT COMMANDS WITHIN THE SEARCH MENU POPUP
Our Ribbon Control exposes a CustomizeSearchMenu event. This event allows you to
implement custom logic to determine which commands must appear in search
results. v24.1 extends the event's arguments to simplify customization.
New APIs include:
* e.AddHeader(string caption) – Displays the header with a specific caption.
* e.AddItem(BarItem item) – Displays the specified command in search results.
* e.ShowNoMatchesItem – Specifies whether to display “No matches found” when a
search query does not return results.
* C#
void ribbonControl1_CustomizeSearchMenu(object sender, RibbonSearchMenuEventArgs e) {
if(e.SearchString.ToLower() == "format") {
e.AddHeader("Text Formatting");
e.AddItem(ribbonControl1.Items["iBold"]);
e.AddItem(ribbonControl1.Items["iItalic"]);
e.AddItem(ribbonControl1.Items["iUnderline"]);
e.ShowNoMatchesItem = false;
}
}
We introduced the UseCustomRibbonSearch property for those who prefer to
generate search results from scratch. When set to true, our Ribbon Control does
not auto-populate search results (e.Menu.ItemLinks). You won't need to clear
pre-built search results before adding your own commands.
Use the RibbonControl.OptionsSearchMenu property to access search-related
settings. These include:
* SearchItemPosition
* SearchItemShortcut
* UseCustomRibbonSearch
#MERGE RIBBON MESSAGES (MDI)
The Ribbon control of a parent Form displays messages (Office-inspired flyout
notifications and alerts) of Ribbon controls displayed on child MDI Forms when
merged:
Use the RibbonControl.MergedMessages property to access and manage merged
messages.
DATA EDITORS
#DATEEDIT – DATEONLY TYPE SUPPORT
Our WinForms DateEdit control now supports the DateOnly data type. The following
properties accept DateOnly values:
* public DateOnly DateOnly { get; set; }
* public object MinDate { get; set; }
* public object MaxDate { get; set; }
#SIMPLE BUTTON – CUSTOM PAINTING
We implemented a new CustomDraw event. Handle this event to paint our WinForms
Simple Button manually.
* C#
void simpleButton1_CustomDraw(object sender, DevExpress.XtraEditors.ButtonCustomDrawEventArgs e) {
if(e.Info.State == DevExpress.Utils.Drawing.ObjectState.Hot) {
e.Cache.FillRectangle(Brushes.Orange, e.Bounds);
e.DefaultDrawImage();
e.DefaultDrawText();
e.Handled = true;
}
}
#UNIFIED PADDING SETTINGS FOR TEXTBOX-BASED EDITORS
v24.1 ships with consistent padding settings across all DevExpress Textbox-based
data editor types (such as TextEdit, SpinEdit, DateEdit, MemoEdit, etc.). These
settings allow you to maintain visual consistency without having to specify
different padding options for different editor types.
Use Properties.TextPadding and Properties.Padding properties to specify text and
content paddings within the text box.
#MEMOEDIT – ENHANCED WXI SKIN VISUALIZATION
We enhanced the visualization of MemoEdit borders and added scrollbar
colorization within our WXI Skin. Accordingly, the DevExpress WinForms MemoEdit
now supports DevExpress Skin colors.
* C#
memoEdit1.Properties.Appearance.BackColor = DevExpress.LookAndFeel.DXSkinColors.FillColors.Question;
#DISTINGUISH USER VS. CODE MODIFICATIONS TO THE EDITOR'S VALUE
You can now distinguish between modifications made by a user and those made
programmatically (in code) to the editor's value. We added a e.ModifiedByUser
parameter to arguments for the EditValueChanging event:
* C#
void textEdit1_EditValueChanging(object sender, DevExpress.XtraEditors.Controls.ChangingEventArgs e) {
if(e.ModifiedByUser) {
// ...
}
}
DOCUMENT MANAGER
#ADDING CONTENT AT DESIGN-TIME
Our Document Manager supports deferred loading. To leverage this capability,
document content must be generated at runtime in the QueryControl event handler.
While this technique offers flexibility and performance benefits, it may be
complicated for simple usage scenarios (where all documents are known at
design-time).
In v24.1, you can add User Controls and Forms to documents at design time (in
Visual Studio).
DOCKING LIBRARY
#LAYOUT RESTORE VALIDATION
You can now ensure the integrity and consistency of docking layouts during
deserialization. Inconsistency or corruption of deserialized layout data can
result in unexpected behavior, visual artifacts, or application crashes. The
RestoreLayoutError event allows you to prevent loading of broken layouts or to
handle/fix layout-related issues as needed:
* C#
using DevExpress.Utils.Serializing;
void dockManager1_RestoreLayoutError(object sender, RestoreLayoutErrorEventArgs e) {
foreach (var exception in e.Exceptions) {
if (exception is TabContainerActiveChildNotSetException activeChildException)
activeChildException.Panel.ActiveChild = activeChildException.Panels[1];
}
e.Throw = false;
}
Note: we also added layout restore validation in our WinForms Document Manager
(RestoreLayoutError).
HTML & CSS SUPPORT
#PRE-WRITTEN CODE SNIPPETS FOR HTML/CSS
v24.1 includes 40 pre-written HTML & CSS code snippets in our HTML Template
Designer for Visual Studio. These are optimized code snippets that address
common HTML-related tasks.
Code snippets include:
* Basic Elements (border, picture, link, tooltip, list, table)
* Text & Font Snippets
* Layout Snippets
* Colors & Visual Elements
* Binding Snippets
#ALIGN EDITOR TEXT
You can now use standard CSS properties to align DevExpress editor content
(horizontally or vertically) used within HTML templates.
PDF VIEWER
#SIGNATURE INFO PANEL
With our new Signature Info panel, you can display detailed information for each
signature in the loaded document and verify signature validity.
When you open a document, the PDF Viewer verifies signatures and displays
associated status in the Signature panel (valid, invalid, or unknown).
In addition, the new panel displays the following signature-related information:
* Location of the signature in the document
* Signer's information
* Reasons the signature was created
* Date and time when the document was singed and modified once it was signed
* Certificate information.
Documentation
#LAYERS
PDF document layers allow you to selectively view or hide specific content
sections. The main purpose of layers is to control the visibility of graphics
objects rendered in a PDF document across different states (when you view or
print a PDF document).
We added a Layers panel to display all layers contained in a document. This new
capability allows you to change layer visibility via the UI. Click the check box
next to the layer's name in the new Layers panel to display/hide a given
document layer. Visible layers are highlighted using an “eye” icon; layers that
cannot be hidden because of a document configuration do not have a check box
next to their name.
With the power of the PDF Facade API, you can also access and manage layer
visibility at runtime when you preview or print your PDF documents. Call the
PdfViewerExtensions.GetDocumentFacade extension method to obtain the
PdfDocumentFacade class object (it allows you to change the PDF document without
access to its inner structure) and use the
PdfDocumentFacade.OptionalContentVisibility collection to change the visibility
state for the required document layers in code.
The PdfDocumentFacade class is defined in the DevExpress.Docs.v24.1.dll
assembly. Add this assembly to your project or install the
DevExpress.Document.Processor NuGet Package to use the PdfDocumentFacade
members. You need a license for the DevExpress Office File API Subscription or
DevExpress Universal Subscription to use this class in production code.
* C#
pdfViewer.LoadDocument("layers.pdf");
PdfDocumentFacade documentFacade = pdfViewer.GetDocumentFacade();
// Set visibility for each Layer
documentFacade.OptionalContentVisibility.Groups[0].Visible = false;
documentFacade.OptionalContentVisibility.Groups[1].Visible = false;
documentFacade.OptionalContentVisibility.Groups[2].Visible = true;
Documentation
RICH TEXT EDITOR
#ACCESSIBILITY - SCREEN READERS SUPPORT
v24.1 adds support for key accessibility-related requirements, including the
ability for assistive technologies (such as screen readers) to read text in the
body of a document, alternative text and names for images, text box content,
headers, and footers.
#EXPORT TO ACCESSIBLE PDF
We extended accessibility-related support to the following elements when
exporting Word documents to accessible PDF files:
* Table of Contents tagging
* Metadata fields
* Alt text handling
* Tables
* Floating objects.
Adobe Acrobat Pro and PDF Accessibility Checker 2024 were used for quality
control. Our test documents successfully passed validation for PDF/UA
compatibility and WCAG 2.1 compliance.
Accessibility-related export enhancements are available out-of-the-box when you
specify the PdfUACompatibility option:
* C#
using System.IO;
using DevExpress.XtraRichEdit;
//...
using(FileStream stream =
new FileStream(resultFilePath, FileMode.Create, FileAccess.Write, FileShare.Read)) {
PdfExportOptions exportOptions = new PdfExportOptions();
exportOptions.PdfUACompatibility = PdfUACompatibility.PdfUA1;
richEditControl.ExportToPdf(stream, exportOptions);
}
#DECORATIVE SHAPES
We added a Decorative property for the Shape class to mark document graphics
(pictures, shapes, and charts) as decorative. Decorative shapes add visual
interest, but they are not informative. Thus, you do not need to specify Alt
Text (meaningful description) for decorative objects when you generate an
accessible document.
#MATH EQUATIONS
Our Rich Text Editor now preserves Math Equations when saving a document. You
can import your Word documents with Math Equations in our WinForms Rich Text
Editor and save them to the RTF and OpenXml (.docx/.docm) formats without
content loss.
Note: Math Equations will be printed or exported to PDF only if the source
document contains a fallback image for a Math Equation. To suppress Math
Equation import, set the DocumentCapabilities.MathEquations property to
DocumentCapability.Disabled.
#GUTTER AND MIRRORED MARGINS
The DevExpress WinForms Rich Text Editor v24.1 allows you to specify gutter
margins - extra space that ensures binding will not obscure text on printed
pages. You can specify gutter position (top, left, and right) and margin size.
Use the Document.GutterAtTop, SectionMargins.GutterPosition, and
SectionMargins.Gutter properties to address specific usage requirements.
The following code snippet adds a left gutter to the first document section:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
//...
richEditControl.LoadDocument(@"Documents//Alice.docx");
Document document = richEditControl.Document;
Section firstSection = wordProcessor.Document.Sections[0];
var pageMargins = firstSection.Margins;
pageMargins.GutterPosition = GutterPosition.Left;
pageMargins.Gutter = Units.InchesToDocumentsF(1);
richEditControl.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
Our new Document.MarginType property allows you to define a regular or mirrored
margin type. Enable mirrored margins if you print on both sides of the paper and
want to bind the printout.
The following code snippet enables mirrored margins and specifies an additional
space value:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
//...
richEditControl.LoadDocument(@"Documents//Alice.docx");
Document document = richEditControl.Document;
// Enable mirrored margins
document.MarginsType = MarginsType.Mirrored;
foreach (Section section in richEditControl.Document.Sections) {
var pageMargins = section.Margins;
// Set the value for mirrored margins
pageMargins.Gutter = Units.InchesToDocumentsF(0.5f);
}
richEditControl.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
New UI elements are also available.
Documentation
#IMAGE EXPORT API
v24.1 includes new cross-platform APIs to export Word document pages to an
image. This new capability allows you to generate document previews. With our
new APIs, you can convert document pages to raster and vector images (PNG, JPEG,
BMP, multi-page Tiff, emf), save them as physical files on the disk or obtain a
list of image streams for further processing in code. You can also set image
background color, modify output image resolution, or generate thumbnail images
with a specified size.
The new API is available via the RichEditDocumentServerExtensions.ExportToImage
extension method of the Document object.
Please note that the RichEditDocumentServerExtensions class is defined in the
DevExpress.Docs.v24.1.dll assembly. Add this assembly to your project or install
the "DevExpress.Document.Processor" NuGet Package to use the
RichEditDocumentServerExtensions members. You need a license for the DevExpress
Office File API Subscription or DevExpress Universal Subscription to use this
class in production code.
The following code snippet exports the first document page to an image with a
specified size and JPEG format:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.Export.Image;
using DevExpress.Drawing;
richEditControl.LoadDocument(@"C:\Documents\Alice.docx");
//...
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Jpeg;
options.PageRange = "1";
options.LargestEdgeLength = 1080;
richEditControl.Document.ExportToImage(@"C:\Documents\Image.jpeg", options);
#EXPORT DOCUMENT PAGES TO SVG
Our new Image Export APIs allow you to export document pages to SVG. Use the
RichEditImageExportOptions.Format option to set SVG as a target image format.
* C#
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Svg;
options.PageRange = "1";
richEditControl.Document.ExportToImage(@"C:\Documents\Image.svg", options);
SVG Export is also available from the user interface - open the Print Preview
dialog, click the Export to Image button, choose the SVG format in the Image
Options dialog and complete document export.
SVG SCROLL CURSOR
WinForms data-aware controls with scrollable content now ship with
DPI-independent scroll cursor (the cursor that appears when the user presses the
middle mouse button), providing smooth and precise navigation regardless of
screen resolution.
SPREADSHEET
#ACCESSIBILITY ENHANCEMENTS - DECORATIVE SHAPES
We added a Decorative property for the Shape class to mark document graphics
(pictures, shapes and charts) as decorative. Decorative shapes add visual
interest, but they are not informative. Thus, you do not need to specify Alt
Text (meaningful description) for decorative objects when you generate an
accessible document.
#JUSTIFY & DISTRIBUTED TEXT ALIGNMENT
v24.1 adds support for Justify and Distributed horizontal alignment types within
Spreadsheet cells. Excel files using these alignment options can be printed and
exported to PDF.
You can use the Cell.Alignment.Horizontal property to specify horizontal
alignment in code.
The following code snippet specifies alignment in code:
* C#
var workbook = new Workbook();
var worksheet = workbook.Worksheets[0];
Cell cellA1 = worksheet.Cells["A1"];
cellA1.Value = "Justified and top";
cellA1.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Justify;
cellA1.Alignment.Vertical = SpreadsheetVerticalAlignment.Top;
workbook.ExportToPdf("Result.pdf");
#SORT AND FILTER BY COLOR
The DevExpress WinForms Spreadsheet ships with enhanced filter and sort-related
capabilities. We added new APIs that can sort and filter workbook data by
background and font color. Cell ranges filtered/sorted by cell color can also be
printed and exported to PDF.
Our Sorting APIs include new Worksheet.Sort method overloads designed to sort a
specified range by font color or fill setting (background color and pattern).
The following code snippet sorts cell values across two cell ranges - the first
is sorted by a red font color and the second is sorted by fill settings
specified for the first cell in the range:
* C#
spreadsheetControl.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
// Sort cell range by font color
worksheet.Sort(worksheet["B2:B10"], Color.Red);
// Sort cell range by fill color
worksheet.Sort(worksheet["D2:D10"], worksheet["D2"].Fill);
To filter cells by font or background color, you need to apply an auto-filter to
the required cell range or table. Once complete, you need to obtain the required
column from the AutoFilter.Columns collection and call one of the following
methods:
* AutoFilterColumn.ApplyFillColorFilter(Color)
* AutoFilterColumn.ApplyFillFilter(Fill)
* AutoFilterColumn.ApplyFontColorFilter(Color)
The following code snippet uses these methods for both cell range and table:
* C#
spreadsheetControl.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
// Apply an auto-filter to a cell range and filter the first column by font color
worksheet.AutoFilter.Apply(worksheet["B1:B10"]);
worksheet.AutoFilter.Columns[0].ApplyFontColorFilter(Color.Red);
// Create a table, apply an auto-filter and filter the first column by fill color
Table table = worksheet.Tables.Add(worksheet["B12:B21"], true);
table.AutoFilter.Apply();
table.AutoFilter.Columns[0].ApplyFillColorFilter(Color.Red);
In addition, our new APIs allow you to sort data across a filtered range (when
auto-filter is enabled) and sort cells by their values/colors simultaneously
(using sorting conditions).
Documentation: Sort Cell Range by Color
#EXPORT CELL RANGE TO SVG
In this release, we enhanced our CellRangeExtensions.ExportToImage method and
added support for the SVG image format.
The CellRangeExtensions class is defined in the DevExpress.Docs.v24.1.dll
assembly. Add this assembly to your project or install the
DevExpress.Document.Processor NuGet Package to use CellRangeExtensions members.
To use this class in production code, you will need an active DevExpress Office
File API or DevExpress Universal Subscription.
* C#
spreadsheetControl.LoadDocument("InvestmentPortfolio.xlsx", DocumentFormat.Xlsx);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
worksheet.Range["B18:I30"].ExportToImage("cell_range_image.svg", ImageFileFormat.Svg);
SVG Export is also available from the user interface - open the Print Preview
dialog, click the Export to Image button, choose the SVG format in the Image
Options dialog and complete document export.
ACCESSIBILITY AND UI AUTOMATION
#ACCESSIBLE KEYBOARD NAVIGATION
TabPane & NavigationPane
We added keyboard navigation support to our WinForms TabPane and Navigation Pane
controls (much like that of the XtraTabControl). Keyboard focus is now managed
as follows:
* Right/Left Arrow — Activates the Next/Previous page.
* Ctrl+Tab / Ctrl+Shift+Tab — Activates the Next/Previous page and focuses the
tab header or UI control displayed on the page.
* Home — Activates the first page.
* End — Activates the last page.
Additional API includes:
* AllowNavigationThroughPages — Activate this option to focus the tab header
(rather than the UI control displayed on the page) when the user navigates
using the Tab key. This option is disabled by default.
* ShowHeaderFocus — Displays/hides the focus rectangle.
TextBox-based Data Editors in BarEditItems
We improved keyboard navigation within our Ribbon UI and Toolbars. Keyboard
focus is now appropriately managed to mimic behaviors found in Microsoft Word.
Specifically, when the BarEditItem has focus and the user presses an arrow key,
the BarEditItem retains focus, allowing navigation within the editor.
v24.1 exposes new properties that allow you to suppress a keyboard key (Alt or
Control) for bar items with embedded editors (BarEditItem):
* BarManager.SuppressModifierKey — This global setting specifies the behavior
for all BarEditItems within the Form.
* BarEditItem.SuppressModifierKey — Specifies the behavior for a specific
BarEditItem.
The following example activates MS Word-inspired behavior for a bar item with a
combo box. Instead of using the Alt+DownArrow combination to open the dropdown,
the user simply needs to press DownArrow:
* C#
public Form1() {
InitializeComponent();
barItemCombobox.SuppressModifierKey = DevExpress.XtraEditors.SuppressKeys.Alt;
}
ButtonEdit-based Editors
We've optimized the keyboard focus within our ButtonEdit-related controls to
ensure that it follows a logical and intuitive sequence. Users can easily tab
from the edit box to buttons, navigate through buttons using Left/Right keys,
press buttons (Enter/Space), and tab back to the edit box (Escape or Shift+Tab).
Use the WindowsFormsSettings.KeyboardNavigationExtension property to enable this
behavior for DevExpress TabPane, NavigationPane, and all ButtonEdit controls
within the application.
* C#
public Form1() {
InitializeComponent();
DevExpress.XtraEditors.WindowsFormsSettings.KeyboardNavigationExtensions = DevExpress.XtraEditors.KeyboardNavigationExtensions.All;
}
Use the AllowButtonNavigation property to enable keyboard navigation for a
specific ButtonEdit control.
Additional options include:
* In-place Mode Support
* Right to Left Mode Support
* Advanced Mode Support
WinForms TileView (Kanban)
End-users can now focus tile group header/footer buttons with the keyboard and
use arrow keys for left/right navigation.
WinForms Diagram Control
We improved keyboard navigation in the DevExpress WinForms Diagram control.
Users can now use the following keyboard keys:
* Ctrl++ – Zooms in on the canvas.
* Ctrl+- – Zooms out the canvas.
* Ctrl+Space – Expands/collapses the focused container.
* F4 – Opens the Properties window.
Column Filter Popup
When a user opens an Excel Filter Popup, the popup window automatically receives
focus. Users can navigate between popup window UI elements using the keyboard.
#SCREEN READER RELATED ENHANCEMENTS
v24.1 ships with improved accessibility across our WinForms UI control library.
Screen readers (such as Narrator and NVDA) can now pronounce the following user
actions and properties:
* Checking an item in the Data Grid Column Customization Menu.
* Expanding/collapsing an item in the DevExpress Accordion Control.
* Specifying criteria within the DevExpress Grid Auto Filter Row.
* Focusing tokens in the Token Editor (a Screen reader pronounces tokes).
* Focusing a group in the DevExpress WinExplorer View.
* Focusing a cell in the DevExpress Grid New Item Row.
* Navigating through card fields in the DevExpress CardView.
* TextEdit.Properties.AdvancedModeOptions.Label
* TextEdit.Properties.NullValuePrompt
Additional enhancements:
* When a user enters an incorrect expression in the Expression Editor, the
screen reader pronounces the error message.
* When a user uses the integrated Find Panel to search for specific
information, the screen reader pronounces the number of search results.
#ACCESSKEY AND ACCELERATORKEY SUPPORT IN RIBBON UI AND TOOLBARS
Ribbon UI elements (Bar items, Ribbon pages, BackStageView, Group Caption
button, and Application button) now expose the following accessibility-related
properties:
* AccessKey in MSAA and UI Automation
* AcceleratorKey in UI Automation.
Note: We set these properties based on values of properties such as
ItemShortcut.
MISCELLANEOUS ENHANCEMENTS
#ASSIGN IMAGES BY KEY/NAME
Image options include a new ImageKey string setting. Use it to specify an image
by its "name". Unlike ImageIndex, where adding or removing images can change the
position of existing images in the collection (requiring the ImageIndex property
to be updated), the ImageKey property identifies an image regardless of its
position in the collection (search in the collection is done by the image name).
Note: ImageKey takes priority over ImageIndex (if both properties are
specified).
PERFORMANCE IMPROVEMENTS
#IMPROVED WINDOWS FORMS OUT-OF-PROCESS DESIGNER
We were in close collaboration with the Microsoft dev team over the last few
months, and Microsoft has recently released a Visual Studio 2022 update, which
improves form load performance across a number of .NET Core / .NET usage
scenarios.
These performance enhancements are not tied to any DevExpress version because
they are implemented at the Visual Studio core level (based on our feedback
associated with problematic internal routines). From Microsoft release notes:
Through a fruitful collaboration with a key partner, we are thrilled to announce
substantial enhancements to the WinForms server process TypeResolutionService.
These enhancements have yielded remarkable design time performance improvements,
ranging from 30% to an impressive 50% in typical line of business applications.
Notably, these enhancements particularly shine during scenarios that trigger
server process restart and designer reload, such as project rebuilds or
adjustments in project references.
At the heart of these performance improvements lies a new mechanism implemented
by our team, prioritizing assemblies crucial for designer load. We encourage you
to explore the updated designer and share your invaluable feedback through VS
Feedback channel so that we can continue improving WinForms designer
performance.
You can cut an additional 1-2 seconds from designer startup (if you do not need
all DevExpress WinForms components simultaneously on your forms) by using the
following smaller packages (like DevExpress.Win.Grid, DevExpress.Win.TreeList,
DevExpress.Win.Charts, etc.) instead of the large DevExpress.Win.Design package.

ACCESSIBILITY AND UI AUTOMATION
#ASSISTIVE TECHNOLOGIES (SCREEN READERS) – COMPATIBILITY ENHANCEMENTS
We enhanced our WPF Accessibility Tree for the following UI controls (assistive
technologies obtain the necessary information to help address WCAG accessibility
guidelines):
* Layout Control
* Tab Control
* Ribbon Gallery
* Built-in Dialogs and Forms (such as Column Filter Popup, Bars Customization
Window).
Screen readers (such as Narrator and NVDA) can now pronounce the following
actions:
* The user selects a row/node with the keyboard in the DevExpress WPF Grid or
WPF TreeList control.
* The user expands/collapses a node.
* The user checks/unchecks a node.
* The user moves focus to a WPF Ribbon Bar item.
* The WPF Grid’s cell value is modified in code.
Screen readers can now access the following information:
* Column/band name for the focused WPF Grid cell.
* Focused WPF Grid row cell values in multi row selection mode.
* The position of the focused cell among visible rows/columns.
* The name of the New Item Row in DevExpress WPF Grid and TreeList controls.
* Active cell editor type in the DevExpress WPF Grid.
* DevExpress WPF ThemedMessageBox text.
* DevExpress WPF Step Progress Bar items.
#ACCESSIBLE KEYBOARD NAVIGATION
WPF Diagram Control
We improved keyboard navigation in the DevExpress WPF Diagram control. Users can
now use the following keyboard keys:
* Ctrl++ – Zooms in on the canvas.
* Ctrl+- – Zooms out the canvas.
* Ctrl+Space – Expands/collapses the focused container.
* F4 – Opens the Properties window.
WPF Ribbon Control
We improved keyboard navigation within our WPF Ribbon control. Users can move
focus to the "Expand/Collapse Ribbon" button using the Tab or Arrow key (Space
and Enter keys expand/collapse the Ribbon).
v24.1 ships with improved keyboard navigation within BarSplitButtonItem:
* Enter – Executes the main action.
* Alt + DownArrow – Invokes the drop-down window.
Row Context Menus in the WPF Grid Control
Pressing the Context Menu Button invokes a context menu for the focused row.
WPF Office Navigation Bar
Users can now press Space or Enter to invoke an action associated with the
focused item.
WPF Accordion Control
Pressing the Shift+Tab shortcut focuses the "Expand/Collapse" button.
WPF Track Bar Editor
Users can now focus each thumb of the range track bar editor with the keyboard.
DATEONLY & TIMEONLY TYPE SUPPORT
DevExpress WPF Data Grid now supports DateOnly and TimeOnly data types (in .NET
applications). These data types offer the following advantages (versus the
traditional DateTime type): usage clarity, improved database compatibility, less
space during serialization, and the ability to mitigate potential
errors/inconsistencies related to different time zones.
Built-in DateOnly/TimeOnly support extends to:
* UI Elements Related to Data Filtering (Column Filter Popup, Filter Editor,
Expression Editor, Automatic Filter Row)
* Conditional Formatting Rules
* Data Summaries
* Data Grouping
* Unbound Columns
* Criteria Operators
* Masks
* Search
DATA GRID
#EXPORT CELL IMAGES TO EXCEL
The WPF Data Grid now exports images (raster and SVG) displayed within cells of
bound and unbound columns to XLSX format in data-aware export mode. Cell images
are exported as a Byte[] array. To activate this feature, set the
AllowCellImages property to DefaultBoolean.True.
* C#
XlsxExportOptionsEx options = new XlsxExportOptionsEx();
options.AllowCellImages = DevExpress.Utils.DefaultBoolean.True;
view.ExportToXlsx("grid_export.xlsx", options);
Handle the CustomizeCell event to customize cell images or replace values with
images (based on export conditions) before the Grid Control generates the output
document.
Documentation
#FILTER BY COLOR AND ICON SET
We extended the user experience when using the WPF Grid Control (in TableView
and TreeListView). Users can quickly filter data based on visual criteria (Icon
Set and Color Scale format conditions). This functionality is available to users
via the column header's context menu if conditional formatting is applied:
New APIs include:
* TableView.AllowFormatConditionFiltersMenu – Displays/hides the “Format
Condition Filters” submenu in context menus associated with all columns in a
TableView (if conditional formatting is applied).
* TreeListView.AllowFormatConditionFiltersMenu – Displays/hides the “Format
Condition Filters” submenu in context menus associated with all columns in a
TreeListView (if conditional formatting is applied).
* AllowFormatConditionFiltersMenu – Displays/hides the “Format Condition
Filters” submenu in the context menu associated with a specific column (if
conditional formatting is applied).
#AGGREGATE FILTERS
We added aggregate filter support to our WPF Data Grid. The Data Grid exposes a
new AllowFilterEditorAggregateOperands property that allows users to filter data
by items in bound collection data fields (for example, master-detail data). When
enabled, the grid Filter Editor displays aggregated operands for collection
properties/fields (SUM, COUNT, MIN, MAX, AVG, EXISTS).
You can also customize the operand list (for example, hide unnecessary operands)
for specific data columns using the AllowedAggregateFilters property.
* XAML
<dxg:GridColumn FieldName="Genres" AllowedAggregateFilters="Exists, Count"/>
FONT ICON IMAGES
Support for Font Icon Images was first introduced in our WinForms product line
(Dec 2023). v24.1 extends this feature to our WPF UI library.
Use the DevExpress WPF Image Picker (integrated within Visual Studio) to assign
font icon images to individual UI controls/elements or use our FontIconSource
extension to do the same in code.
If you execute a DevExpress-powered WPF application, it will display icons from
the most recent icon font available in the system. For example, the "Segoe
Fluent Icons" font is used as the default font if both "Segoe Fluent Icons" and
"Segoe MDL2 Assets" fonts are installed.
Use the FontIconSourceExtension.FontFamily property to specify icon font:
* XAML
<dxb:BarButtonItem Glyph="{dx:FontIconSource Glyph=0xf0b4, FontFamily=SegoeMDL2Assets}"/>
You can also select an icon color from predefined values (Red, Green, Blue,
Yellow, Black, and White). These colors are auto modified to match the applied
DevExpress Theme:
* XAML
<dxb:BarButtonItem Glyph="{dx:FontIconSource Glyph=59246, ColorName=Yellow}"/>
And yes, you can use WpfSvgPalette to colorize icons to address design
preferences:
* XAML
<dxb:BarButtonItem Glyph="{dx:FontIconSource Glyph=59246}">
<dx:WpfSvgPalette.Palette>
<dx:WpfSvgPalette>
<SolidColorBrush x:Key="Black" Color="Aqua"/>
</dx:WpfSvgPalette>
</dx:WpfSvgPalette.Palette>
</dxb:BarButtonItem>
Documentation: Font Icon Images
RIBBON & BARS
#SEARCH BOX
A Ribbon-based UI can include dozens of commands across multiple pages. Without
prior experience with a given app, users can struggle to locate appropriate
actions/commands. To minimize usage friction/learning curve, v24.1 ships with a
new WPF Ribbon Search Box.
Specify the SearchItemDisplayMode property to activate the search box in your
WPF app. Our WPF Ribbon compares the search string to command content
(BarButtonItem.Content) to generate search results.
You can enable an item's HideFromSearch option to exclude it from search. For
more granular control, use the following events:
* ItemsRequested – Fires when the searchable items list is generated. The event
allows you to modify search results before applying the search criteria (for
example, to add additional items based on a condition).
* ItemFiltering – Fires for each item before it is displayed in search results.
The event allows you to hide the item from search results.
* ItemsFiltered – Notifies when a search is complete.
Additional settings include:
* SearchDelay – Specifies the delay in milliseconds between the last text
change and the text search.
* SearchItemFocusShortcut – Specifies the keyboard shortcut used to focus the
search box (the default shortcut is "Ctrl+F").
* ShowDescriptionInSearchResults - Specifies whether to display the path to
items within the DevExpress WPF Ribbon UI (Category > Page > Group).
Run Demo
To execute this demo, you must first
install the DevExpress WPF product library .
PDF VIEWER
#SIGNATURE INFO PANEL
With our new Signature Info panel, you can display detailed information for each
signature in the loaded document and verify signature validity.
When you open a document, the PDF Viewer verifies signatures and displays
associated status in the Signature panel (valid, invalid, or unknown).
In addition, the new panel displays the following signature-related information:
* Location of the signature in the document
* Signer's information
* Reasons the signature was created
* Date and time when the document was singed and modified once it was signed
* Certificate information.
Documentation
#LAYERS
PDF document layers allow you to selectively view or hide specific content
sections. The main purpose of layers is to control the visibility of graphics
objects rendered in a PDF document across different states (when you view or
print a PDF document).
We added a Layers panel to display all layers contained in a document. This new
capability allows you to change layer visibility via the UI. Click the check box
next to the layer's name in the new Layers panel to display/hide a given
document layer. Visible layers are highlighted using an “eye” icon; layers that
cannot be hidden because of a document configuration do not have a check box
next to their name.
With the power of the PDF Facade API, you can also access and manage layer
visibility at runtime when you preview or print your PDF documents. Call the
PdfViewerExtensions.GetDocumentFacade extension method to obtain the
PdfDocumentFacade class object (it allows you to change the PDF document without
access to its inner structure) and use the
PdfDocumentFacade.OptionalContentVisibility collection to change the visibility
state for the required document layers in code.
The PdfDocumentFacade class is defined in the DevExpress.Docs.v24.1.dll
assembly. Add this assembly to your project or install the
DevExpress.Document.Processor NuGet Package to use the PdfDocumentFacade
members. You need a license for the DevExpress Office File API Subscription or
DevExpress Universal Subscription to use this class in production code.
* C#
pdfViewer.LoadDocument("layers.pdf");
PdfDocumentFacade documentFacade = pdfViewer.GetDocumentFacade();
// Set visibility for each Layer
documentFacade.OptionalContentVisibility.Groups[0].Visible = false;
documentFacade.OptionalContentVisibility.Groups[1].Visible = false;
documentFacade.OptionalContentVisibility.Groups[2].Visible = true;

RICH TEXT EDITOR
#EXPORT TO ACCESSIBLE PDF
We extended accessibility-related support to the following elements when
exporting Word documents to accessible PDF files:
* Table of Contents tagging
* Metadata fields
* Alt text handling
* Tables
* Floating objects.
Adobe Acrobat Pro and PDF Accessibility Checker 2024 were used for quality
control. Our test documents successfully passed validation for PDF/UA
compatibility and WCAG 2.1 compliance.
Accessibility-related export enhancements are available out-of-the-box when you
specify the PdfUACompatibility option:
* C#
using System.IO;
using DevExpress.XtraRichEdit;
//...
using(FileStream stream =
new FileStream(resultFilePath, FileMode.Create, FileAccess.Write, FileShare.Read)) {
PdfExportOptions exportOptions = new PdfExportOptions();
exportOptions.PdfUACompatibility = PdfUACompatibility.PdfUA1;
richEditControl.ExportToPdf(stream, exportOptions);
}
#DECORATIVE SHAPES
We added a Decorative property for the Shape class to mark document graphics
(pictures, shapes, and charts) as decorative. Decorative shapes add visual
interest, but they are not informative. Thus, you do not need to specify Alt
Text (meaningful description) for decorative objects when you generate an
accessible document.
#MATH EQUATIONS
Our Rich Text Editor now preserves Math Equations when saving a document. You
can import your Word documents with Math Equations in our WinForms Rich Text
Editor and save them to the RTF and OpenXml (.docx/.docm) formats without
content loss.
Note: Math Equations will be printed or exported to PDF only if the source
document contains a fallback image for a Math Equation. To suppress Math
Equation import, set the DocumentCapabilities.MathEquations property to
DocumentCapability.Disabled.
#GUTTER AND MIRRORED MARGINS
The DevExpress WPF Rich Text Editor v24.1 allows you to specify gutter margins -
extra space that ensures binding will not obscure text on printed pages. You can
specify gutter position (top, left, and right) and margin size. Use the
Document.GutterAtTop, SectionMargins.GutterPosition, and SectionMargins.Gutter
properties to address specific usage requirements.
The following code snippet adds a left gutter to the first document section:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
//...
richEditControl.LoadDocument(@"Documents//Alice.docx");
Document document = richEditControl.Document;
Section firstSection = wordProcessor.Document.Sections[0];
var pageMargins = firstSection.Margins;
pageMargins.GutterPosition = GutterPosition.Left;
pageMargins.Gutter = Units.InchesToDocumentsF(1);
richEditControl.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
Our new Document.MarginType property allows you to define a regular or mirrored
margin type. Enable mirrored margins if you print on both sides of the paper and
want to bind the printout.
The following code snippet enables mirrored margins and specifies an additional
space value:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
//...
richEditControl.LoadDocument(@"Documents//Alice.docx");
Document document = richEditControl.Document;
// Enable mirrored margins
document.MarginsType = MarginsType.Mirrored;
foreach (Section section in richEditControl.Document.Sections) {
var pageMargins = section.Margins;
// Set the value for mirrored margins
pageMargins.Gutter = Units.InchesToDocumentsF(0.5f);
}
richEditControl.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
New UI elements are also available.
Documentation
#IMAGE EXPORT API
v24.1 includes new cross-platform APIs to export Word document pages to an
image. This new capability allows you to generate document previews. With our
new APIs, you can convert document pages to raster and vector images (PNG, JPEG,
BMP, multi-page Tiff, emf), save them as physical files on the disk or obtain a
list of image streams for further processing in code. You can also set image
background color, modify output image resolution, or generate thumbnail images
with a specified size.
The new API is available via the RichEditDocumentServerExtensions.ExportToImage
extension method of the Document object.
Please note that the RichEditDocumentServerExtensions class is defined in the
DevExpress.Docs.v24.1.dll assembly. Add this assembly to your project or install
the "DevExpress.Document.Processor" NuGet Package to use the
RichEditDocumentServerExtensions members. You need a license for the DevExpress
Office File API Subscription or DevExpress Universal Subscription to use this
class in production code.
The following code snippet exports the first document page to an image with a
specified size and JPEG format:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.Export.Image;
using DevExpress.Drawing;
richEditControl.LoadDocument(@"C:\Documents\Alice.docx");
//...
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Jpeg;
options.PageRange = "1";
options.LargestEdgeLength = 1080;
richEditControl.Document.ExportToImage(@"C:\Documents\Image.jpeg", options);
#EXPORT DOCUMENT PAGES TO SVG
Our new Image Export APIs allow you to export document pages to SVG. Use the
RichEditImageExportOptions.Format option to set SVG as a target image format.
* C#
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Svg;
options.PageRange = "1";
richEditControl.Document.ExportToImage(@"C:\Documents\Image.svg", options);
SVG Export is also available from the user interface - open the Print Preview
dialog, click the Export to Image button, choose the SVG format in the Image
Options dialog and complete document export.
PROPERTY GRID
#CUSTOMIZE ROW APPEARANCE
We added a PropertyGridControl.RowStyle property. Use this property to customize
row appearance/style settings.
As you would expect from a DevExpress WPF grid-based control, you have full
control over row appearance. You can apply row styles based on a condition (use
the WPF PropertyGrid's RowStyleSelector property or standard WPF trigger-based
techniques), or you can use the new AlternationCount property to alternate row
styles.
* XAML
<dxprg:PropertyGridControl ...
AlternationCount="3">
<dxprg:PropertyGridControl.RowStyle>
<Style TargetType="dxprg:RowControl">
<Style.Triggers>
<Trigger Property="ItemsControl.AlternationIndex" Value="1">
<Setter Property="Background" Value="#122C2C2C"/>
</Trigger>
<Trigger Property="ItemsControl.AlternationIndex" Value="2">
<Setter Property="Background" Value="LightGray"/>
</Trigger>
</Style.Triggers>
</Style>
</dxprg:PropertyGridControl.RowStyle>
</dxprg:PropertyGridControl>
SPREADSHEET
#ACCESSIBILITY ENHANCEMENTS - DECORATIVE SHAPES
We added a Decorative property for the Shape class to mark document graphics
(pictures, shapes and charts) as decorative. Decorative shapes add visual
interest, but they are not informative. Thus, you do not need to specify Alt
Text (meaningful description) for decorative objects when you generate an
accessible document.
#JUSTIFY & DISTRIBUTED TEXT ALIGNMENT
v24.1 adds support for Justify and Distributed horizontal alignment types within
Spreadsheet cells. Excel files using these alignment options can be printed and
exported to PDF.
You can use the Cell.Alignment.Horizontal property to specify horizontal
alignment in code.
The following code snippet specifies alignment in code:
* C#
var workbook = new Workbook();
var worksheet = workbook.Worksheets[0];
Cell cellA1 = worksheet.Cells["A1"];
cellA1.Value = "Justified and top";
cellA1.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Justify;
cellA1.Alignment.Vertical = SpreadsheetVerticalAlignment.Top;
workbook.ExportToPdf("Result.pdf");
#SORT AND FILTER BY COLOR
The DevExpress WPF Spreadsheet ships with enhanced filter and sort-related
capabilities. We added new APIs that can sort and filter workbook data by
background and font color. Cell ranges filtered/sorted by cell color can also be
printed and exported to PDF.
Our Sorting APIs include new Worksheet.Sort method overloads designed to sort a
specified range by font color or fill setting (background color and pattern).
The following code snippet sorts cell values across two cell ranges - the first
is sorted by a red font color and the second is sorted by fill settings
specified for the first cell in the range:
* C#
spreadsheetControl.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
// Sort cell range by font color
worksheet.Sort(worksheet["B2:B10"], Color.Red);
// Sort cell range by fill color
worksheet.Sort(worksheet["D2:D10"], worksheet["D2"].Fill);
To filter cells by font or background color, you need to apply an auto-filter to
the required cell range or table. Once complete, you need to obtain the required
column from the AutoFilter.Columns collection and call one of the following
methods:
* AutoFilterColumn.ApplyFillColorFilter(Color)
* AutoFilterColumn.ApplyFillFilter(Fill)
* AutoFilterColumn.ApplyFontColorFilter(Color)
The following code snippet uses these methods for both cell range and table:
* C#
spreadsheetControl.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
// Apply an auto-filter to a cell range and filter the first column by font color
worksheet.AutoFilter.Apply(worksheet["B1:B10"]);
worksheet.AutoFilter.Columns[0].ApplyFontColorFilter(Color.Red);
// Create a table, apply an auto-filter and filter the first column by fill color
Table table = worksheet.Tables.Add(worksheet["B12:B21"], true);
table.AutoFilter.Apply();
table.AutoFilter.Columns[0].ApplyFillColorFilter(Color.Red);
In addition, our new APIs allow you to sort data across a filtered range (when
auto-filter is enabled) and sort cells by their values/colors simultaneously
(using sorting conditions).
Documentation: Sort Cell Range by Color
#EXPORT CELL RANGE TO SVG
In this release, we enhanced our CellRangeExtensions.ExportToImage method and
added support for the SVG image format.
The CellRangeExtensions class is defined in the DevExpress.Docs.v24.1.dll
assembly. Add this assembly to your project or install the
DevExpress.Document.Processor NuGet Package to use CellRangeExtensions members.
To use this class in production code, you will need an active DevExpress Office
File API or DevExpress Universal Subscription.
* C#
spreadsheetControl.LoadDocument("InvestmentPortfolio.xlsx", DocumentFormat.Xlsx);
Worksheet worksheet = spreadsheetControl.ActiveWorksheet;
worksheet.Range["B18:I30"].ExportToImage("cell_range_image.svg", ImageFileFormat.Svg);
SVG Export is also available from the user interface - open the Print Preview
dialog, click the Export to Image button, choose the SVG format in the Image
Options dialog and complete document export.
LIGHTWEIGHT THEMES
#OBTAIN LIGHTWEIGHT THEME PALETTE COLOR
With v24.1, you can effortlessly access color information from existing palettes
that ship as part of our Lightweight themes. This functionality extends to
custom color palettes, allowing you to use colors that reflect the unique
identity of your WPF application.

below and leave your feedback at the end of the section.
Go to the survey now.
NEW SPLITTER COMPONENT
Our new Splitter component allows you to divide a page or section into multiple
adjustable panes.
These panes can be:
* resizable - A handle with a drag icon allows users to modify size.
* collapsible - A handle with an arrow icon allows users to collapse the pane.
If you enable both these properties, the handle displays both icons and users
can both resize/collapse a given pane as desired. If both properties are false,
the handle remains hidden.
The Splitter component can be oriented either vertically or horizontally.
Orientation affects the following pane-related properties (can be specified in
pixels or percents)
* size - Specifies initial width (horizontal orientation) or height (vertical)
of the pane.
* maxSize, minSize - Defines resizing limits for the pane.
* collapsedSize - Specifies the size of a collapsible pane when collapsed.
* Angular
* React
* Vue
* jQuery
<dx-splitter orientation="vertical">
<dxi-item
[collapsible]="true"
size="50%"
minSize="20px"
сollapsedSize="30px"
>
</dxi-item>
</dx-splitter>
const App = () => (
<Splitter orientation="vertical">
<Item
collapsible={true}
size="50%"
minSize="20px"
сollapsedSize="30px"
/>
</Splitter>
);
export default App;
<template>
<DxSplitter orientation="vertical">
<DxItem
:collapsible="true"
size="50%"
min-size="20px"
collapsed-size="30px"
/>
</DxSplitter>
</template>
$('#splitter').dxSplitter({
orientation: 'vertical',
items: [
{
collapsible: true,
size: '50%',
minSize: '20px',
collapsedSize: '30px',
},
],
});
Splitter panes can contain multiple content types, ranging from simple HTML to
complex components. You can place HTML markup inside the item tag or use the
following properties to populate panes with content:
* itemTemplate - Defines a custom template for all panes.
* template - Sets a custom template for each specific pane.
To customize Splitter appearance, specify the separatorSize property to modify
the size of the handle's shorter side. You can also alter color and icons
through CSS.
Enable allowKeyboardNavigation in the Splitter component to control Splitter
actions through shortcut keys, mirroring mouse functions. To see the full list
of shortcuts, refer to the following help topic: Accessibility.
For complex layouts, nest Splitters as illustrated in our demo (which also
highlights use of templates for content insertion).

UI/UX AND API ENHANCEMENTS
#DROPDOWNBUTTON - CUSTOM BUTTON TEMPLATE
With v24.1, you can replace the base button in DropDownButton with custom
content (such as an avatar or multiline text).
* Angular
* React
* Vue
* jQuery
<dx-drop-down-button icon="spindown" template="button-template">
<div *dxTemplate="let data of 'button-template'">
<div class="text-container">
<div class="name"> {{ currentEmployee.FirstName }} {{ currentEmployee.LastName }} </div>
<div class="position"> {{ currentEmployee.Position }} </div>
</div>
<span class="dx-icon-{{ data.icon }} dx-icon"></span>
</div>
</dx-drop-down-button>
const renderButton = (data) => {
return (
<React.Fragment>
<div className="text-container">
<div class="name"> {currentEmployee.FirstName} {currentEmployee.LastName} </div>
<div class="position"> {currentEmployee.Position} </div>
</div>
<span className={"dx-icon-" + data.icon + " dx-icon"}></span>
</React.Fragment>
);
};
export default function App() {
return (
<DropDownButton
icon="spindown"
render={renderButton}
/>
);
}
<template>
<DxDropDownButton

const $textContainer = $('<div class="text-container">').appendTo($element);
$(`<div class='name'>${currentEmployee.FirstName} {currentEmployee.LastName}</div>`).appendTo($textContainer);
$(`<div class='position'> ${currentEmployee.Position} </div>`).appendTo($textContainer);
$(`<span class="dx-icon-${data.icon} dx-icon"></span>`).appendTo($element);
},
});

#MENU/CONTEXTMENU — ITEM SCROLLING
Submenus that exceed page size (in Menu or ContextMenu) can now be scrolled.
You can use CSS stylesheets to customize submenus as needs dictate. For
instance, the following code snippet restricts submenu height in ContextMenu:
* CSS
.dx-context-menu .dx-menu-items-container {
max-height: 200px;
}
In the Menu component, use the onSubmenuShowing function to configure
scroll-related settings. For instance, you can restrict the size of the submenu
when item count surpasses a specified limit:
* Angular
* React
* Vue
* jQuery
onSubmenuShowing({ submenuContainer, itemData } {
if (itemData.items.length > 5) {
submenuContainer.style.maxHeight = this.limitSubmenuHeight ? `200px` : '';
}
}
const onSubmenuShowing = useCallback(({ submenuContainer, itemData }) => {
if (itemData.items.length > 5) {
submenuContainer.style.maxHeight = limitSubmenuHeight ? `200px` : '';
}
}, []);
function onSubmenuShowing({ submenuContainer, itemData } {
if (itemData.items.length > 5) {
submenuContainer.style.maxHeight = limitSubmenuHeight.value ? '200px' : '';
}
}
onSubmenuShowing: ({ submenuContainer, itemData }) => {
if (itemData.items.length > 5) {
$(submenuContainer).css('maxHeight', 200 || '');
}
}

#FORM — GROUP CAPTION CUSTOM CONTENT
Our new Form groupItem.captionTemplate option enables custom content replacement
for group captions.
Select one of the following supported dev frameworks to explore the capabilities
of this new feature:
Angular | React | Vue | jQuery | ASP.NET Core | ASP.NET MVC
#HTML EDITOR — SPELLCHECK AND CSP SUPPORT
The DevExtreme HTML Editor now uses spellcheck functionality across all
supported browsers. As you would expect, this addition enhances text editing
capabilities through real-time spelling correction/suggestion support.
Previous versions required Content Security Policy (CSP) directives when passing
markup with inline styles to our HTML Editor. The DevExtreme HTML Editor v24.1
fully supports CSP.
JS SCRIPT SIZE
In our last major release cycle (v23.2), we reduced CSS size for built-in
themes. In this release cycle, we reduced DevExtreme JS scripts size as follows:
* We updated the ECMAScript compilation target for DevExtreme JS code. This
eliminated the need for complicated syntactic constructions (due to
transpiling) for operations supported by all modern browsers.
* We ceased storage of time zone data. We switched to an internal browser time
zone engine for time zone related operations.
These modifications reduced bundle size by approximately 12%.
ANGULAR 18 SUPPORT
DevExtreme v24.1 supports Angular 18. Earlier versions (such as DevExtreme
v23.2) are not compatible with Angular 18.
Refer to the Angular Update Guide and our Migrate to the New Version help topic
to update your application.
NEW DXHTTPMODULE FOR ANGULAR
#SIMPLIFIED REQUEST INTERCEPTION
Angular HttpClientModule is a module that simplifies HTTP requests. It supports
request and response interceptors, which allows you to introduce capabilities
such as authentication tokens or logging across all HTTP requests.
Previously, our DataSource, FileUploader, and Map components depended on
non-native Angular Ajax requests for server communication.
With v24.1, we transitioned these components from Ajax to the HttpClientModule.
Simply import our DxHttpModule to activate this new functionality.
In the following example, DataSource utilizes DxHttpModule for request
interception.
Online Demo
SHADOW DOM SUPPORT (CTP)
Shadow DOM represents one of three Web Components specifications, complemented
by HTML templates and Custom Elements.
Shadow DOM allows the attachment of a hidden, separate Document Object Model
(DOM) to an element, termed the 'Shadow Host'. This hidden DOM, called the
'Shadow DOM', can contain additional nested Shadow Hosts, forming a structure
known as a Shadow Tree.
It's a direct method to create components with isolated CSS and JavaScript. Many
everyday web interfaces use Shadow DOM (a feature available in all major
browsers).
This release cycle introduces Shadow DOM support in Angular, React, and Vue as a
Community Technology Preview (CTP). Accordingly, you can now use DevExtreme
components inside the Shadow DOM of custom HTML elements (Web Components).
Note: CTPs includes limitations. Refer to our documentation for additional
information: Angular | React | Vue
Select one of the following supported dev frameworks to explore the capabilities
of this new feature:

Online Example
ACCESSIBILITY
v24.1 accessibility-related enhancements include NVDA support for improved
keyboard navigation and pronunciation support across the following components:
* Tabs
* TabPanel
* TagBox
* List
* DropDownButton
* Calendar
* DataGrid with Master-Detail
Additionally, DataGrid and TreeList now meet the Status Messages criterion.
You can now access accessibility compliance (using the AXE® web accessibility
evaluation tool) in many DevExtreme demos including the following:
* Data Grid Overview
* Tree List Overview
* Html Editor Overview
* Charts Overview
Sample AXE accessibility report:
ASP.NET CORE - DATEONLY/TIMEONLY TYPE SUPPORT
DevExtreme ASP.NET Core DataGrid now supports DateOnly and TimeOnly data types.
DateOnly and TimeOnly data types offer the following benefits when compared to
the traditional DateTime data type:
* Usage clarity.
* Improved database compatibility.
* Less space during serialization.
* Ability to mitigate potential errors/inconsistencies related to different
time zones.
The following DataGrid features support DateOnly and TimeOnly data types:
* Filtering-related UI elements (filter row, filter panel, search panel, header
filter)
* Grouping (group interval data operations, both outside and inside a header
filter)
* Summary (min/max, count)
* Razor
<div id="grid"></div>
<script>
$(function() {
$("#grid").dxDataGrid({
columns: [
{
dataField: "orderDateOnly",
dataType: "date",
headerFilter: {
groupInterval: "quarter"
}
},
{
dataField: "orderTimeOnly",
dataType: "time",
},]
});
});
</script>
ASP.NET CORE - DATA VALIDATION
#STANDALONE EDITOR VALIDATION
With this release, you can use Razor syntax (in addition to Model-based method)
to add validation rules directly to DevExtreme Editors.
This method can be used in the following situations:
* Modifying validation rules when model changes are impossible, such as when
models are shared across views.
* Adding extra editors to a view and defining associated validation rules
independent of a model.
* Razor
@(
Html.DevExtreme().TextBoxFor(m => m.StringProperty).ValidationRules(tvr => {
tvr.AddRequired();
})
)
#REMOTE ATTRIBUTE — ADDITIONALFIELDS PROPERTY SUPPORT
In ASP.NET Core, the Remote attribute facilitates client-side validation. Its
AdditionalFields property enables server-based validation of field combinations.
This release introduces support for the AdditionalFields option in the
DevExtreme DataGrid and TreeList.
The following code snippet validates email addresses in a DataGrid column. When
a user enters an email that exists in the database, it determines whether to
create a new profile or edit an existing record (refer to RemoteValidation
Controller). To enable this validation, pass the ID field to AdditionalFields:
* View
* Model
* Remote Validation Controller
@(Html.DevExtreme().DataGrid<EmployeeValidation>()
.Editing(editing => {
editing.AllowUpdating(true);
editing.AllowAdding(true);
})
.Columns(columns => {
columns.AddFor(m => m.ID);
columns.AddFor(m => m.Email);
})
)
using System.ComponentModel.DataAnnotations;
public class EmployeeValidation {
public int ID { get; set; }
[Remote("CheckUniqueEmailAddress", "RemoteValidation", AdditionalFields = nameof(ID))]
public string Email { get; set; }
}
[HttpPost]
public JsonResult CheckUniqueEmailAddress(EmployeeValidation model) {
var isValid = !db.Employees.Any(emp => {
var equals = string.Equals(emp.Email, model.Email, StringComparison.OrdinalIgnoreCase);
return model.ID != emp.ID && equals;
});
return Json(isValid);
}
ASP.NET CORE - RICH TEXT EDITOR
#NEW TABLE API
With v24.1, the DevExpress Rich Text Editor for ASP.NET Core allows you to
modify table layout, decoration, and structure at runtime.
* JavaScript
const columnCount = 5;
const rowCount = 5;
const table = richEdit.document.tables.create(0, columnCount, rowCount);
table.autoFit = false;
table.styleName = "Grid Table 5 Dark Accent 1";
table.width = { type: TableWidthType.Twips, value: 9000 };
table.tableStyleOptions = {
...table.tableStyleOptions,
totalRow: true,
headerRow: true,
}
for (let i = 0; i < table.rows.count; i++) {
const cells = table.rows.getByIndex(i)!.cells;
for (let j = 0; j < cells.count; j++) {
const cell = cells.getByIndex(j)!;
richEdit.document.insertText(cell.interval.start, `Row ${i} Cell ${j}`);
}
}
#HTML EXPORT/IMPORT
The Rich Text Editor now supports the import and export of documents in HTML
format. You can add HTML markup to the main sub-document (insertHtml method
overloads), obtain HTML text and markup of the main sub-document (getHtml method
overloads), and download document content to a file in HTML format.

feedback at the end of the section.
Go to the survey now.
NEW TREELIST (CTP)
Our new Blazor TreeList allows you to organize, display, and navigate
hierarchical data with absolute ease. The component ships with the following
integrated capabilities:
* Data Sorting
* Filter Row with Auto-Generated Editors
* Total Summaries
* Single and Multiple Node Selection
* Focused Row
* Header Bands
* Paging and Scrolling
* Virtual Scrolling
* Toolbar
* Keyboard Support
Online Demo
You will notice that the DevExpress Blazor TreeList and Grid UI components look
and behave in a similar manner. This is not a coincidence. Our Blazor TreeList
and Grid use the same rendering engine and rely upon common logic/algorithms.
Thanks to commonalities between the components, we are in position to add new
functionality to both of components simultaneously in future release cycles.
#BIND TO FLAT DATA
Our Blazor TreeList component can be bound to any traditional data source. Since
the TreeList is designed to display information using a tree structure, its data
source must meet specific requirements. If a data source contains flat data, two
additional fields are necessary to build the appropriate tree structure:
* A field that contains a node’s unique identifier. Assign this field to the
KeyFieldName property.
* A field that contains the unique identifier of a node’s parent. Assign this
field to the ParentKeyFieldName property.
The following example binds the Blazor TreeList component to a flat data source:
* Razor
@inject IEmployeeTaskDataProvider EmployeeTaskDataProvider
<DxTreeList Data="@TreeListData"
KeyFieldName="Id"
ParentKeyFieldName="ParentId">
<Columns>
<DxTreeListDataColumn FieldName="Name" />
<DxTreeListDataColumn FieldName="EmployeeName"/>
<DxTreeListDataColumn FieldName="StartDate" />
<DxTreeListDataColumn FieldName="DueDate" />
</Columns>
</DxTreeList>
@code {
List<EmployeeTask> TreeListData { get; set; }
protected override void OnInitialized () {
TreeListData = EmployeeTaskDataProvider.GenerateData();
}
}
#BIND TO SERVER-SIDE DATA
You can also bind the DevExpress Blazor TreeList component to our
DevExtremeDataSource. This data source allows you to improve TreeList
performance when binding large data sets for the following reasons:
* The TreeList loads child nodes on demand (when user expands a node).
* DevExtremeDataSource performs data filtering operations on the server.
To bind the component to DevExtremeDataSource, you must:
* Assign a GridDevExtremeDataSource instance to the Data property
* Specify KeyFieldName and ParentKeyFieldName properties.
* Specify the HasChildrenFieldName property. This property helps determine
whether a node includes children and if the node requires an expand button.
#BIND TO HIERARCHICAL DATA
If each node in your data source includes a field with a list of child nodes,
assign the field’s name to the ChildrenFieldName property and bind the Data
property to the data source:
* Razor
@inject ISpaceObjectDataProvider SpaceObjectDataProvider
<DxTreeList Data="@TreeListData"
ChildrenFieldName="Satellites">
<Columns>
<DxTreeListDataColumn FieldName="Name"/>
<DxTreeListDataColumn FieldName="TypeOfObject" Caption="Type"/>
<DxTreeListDataColumn FieldName="Mass" Caption="Mass, kg"/>
<DxTreeListDataColumn FieldName="MeanRadius" Caption="Radius, km"/>
</Columns>
</DxTreeList>
@code {
List<SpaceObject> TreeListData { get; set; }
protected override void OnInitialized () {
TreeListData = SpaceObjectDataProvider.GenerateData();
}
}
Alternatively, you can assign a collection of root nodes to the Data property
and handle the ChildrenLoading event to populate nodes with children. In the
event handler, use the Parent argument to determine the processed node and
assign this node’s children to the Children property.
#LOAD DATA ON DEMAND
The DevExpress Blazor TreeList allows you to initially load only root nodes and
retrieve node children when a node is expanded for the first time. To switch the
component to on demand mode, follow the steps below:
* Assign root data items to the Data property.
* Specify the HasChildrenFieldName property.
* Handle the ChildrenLoadingOnDemand event. In the event handler, use the
Parent argument to determine the processed node and assign the node’s
children to the Children event argument.
The following example loads TreeList data on demand:
* Razor
@inject FileSystemDataProvider FileSystemDataProvider
<DxTreeList Data="TreeListData"
HasChildrenFieldName="HasChildren"
ChildrenLoadingOnDemand="TreeList_ChildrenLoadingOnDemand">
<Columns>
<DxTreeListDataColumn FieldName="Name" />
<DxTreeListDataColumn FieldName="Type" />
<DxTreeListDataColumn FieldName="DateModified" />
<DxTreeListDataColumn FieldName="Size" />
</Columns>
</DxTreeList>
@code {
object TreeListData { get; set; }
protected override async Task OnInitializedAsync() {
Data = await FileSystemDataProvider.GetRootItemsAsync();
}
Task TreeList_ChildrenLoadingOnDemand(TreeListChildrenLoadingOnDemandEventArgs e) {
var item = e.Parent as FileSystemDataItem;
e.Children = item.Children;
return Task.CompletedTask;
}
}
NEW HTML EDITOR
Our Blazor HTML Editor allows you to format/display text and visual content and
store it as HTML or Markdown. Users can apply inline formatting and modify font,
size, and color as needs dictate. Additionally, the DevExpress Blazor HTML
Editor offers the following integrated features:
* Block formatting, including headings, text alignment, lists (bullet and
numbered), code blocks, and quotes.
* Variables support (for example, {{companyName}}): Among other use cases, this
capability can be used to generate dynamic email content.
* Toolbar with adaptive layout support.
* Built-in toolbar customization.
* Image Insert: You can upload an image from the local file system or specify a
URL.
* Table support.
* Mentions support.
Online Demo
NEW PDF VIEWER (CTP)
The new DevExpress Blazor PDF Viewer component can display PDF file content
directly in your DevExpress-powered Blazor app. The component allows you to
navigate through the document, set zoom level, print, and download the document.
Additionally, the CTP version of the Blazor PDF Viewer includes a single-page
preview and toolbar customization option (such as rearranging, grouping, hiding,
and adding items)
Online Demo
NEW MAP
The DevExpress Blazor Map component can display geo maps with markers and route
info within your DevExpress-powered Blazor web app. The component retrieves
relevant data from a GIS service (Bing, Google, or GoogleStatic - requires
application authentication with an appropriate API key) and ships with the
following capabilities:
* Marker/route configuration and customization options.
* Built-in map navigation and type controls.
* Manual map adjustment (set Zoom and MapCenter).
* Map and marker "click" support.
Online Demo
NEW POLAR CHART
The DevExpress Polar Chart for Blazor allows you to visualize data within a
polar coordinate system - where each point on a plane is determined by the
distance from the center and the angle from a fixed direction. The DevExpress
Blazor Polar Chart component ships with the following capabilities:
* Multiple series types: line, area, bar, stacked bar, and scatter.
* Continuous, discrete, and logarithmic axis value support.
* Spider web mode.
* Chart element customization: labels, tooltips, legend, and many more.
Online Demo
NEW DATE RANGE PICKER
The DevExpress Date Range Picker for Blazor allows you to select a range of
dates within a single calendar dropdown. The component ships with the following
integrated capabilities:
* Minimum and maximum dates
* Special date highlighting
* Selected date formatting API
* Input validation
* Clear button
* Nullable date support and placeholder
* Automatic support for browser time zone and localization
Online Demo
NEW DROPDOWN BOX
The DevExpress Blazor DropDown Box is a customizable editor - designed to
display/use a variety of UI elements within its drop-down window: from simple
lists and trees, to grids, or any combination therein. You can assign an editor
value programmatically based on page interactions.
The following code snippet adds the DevExpress Blazor Grid to the DropDown Box
popup.
* Razor
<DxDropDownBox Value="Value" QueryDisplayText="QueryText">
<DropDownBodyTemplate>
<DxGrid Data="@GridData" ShowSearchBox="true" SelectedDataItem="@Value"
SelectedDataItemChanged="item => GridSelectedDataItemChanged(item, context.DropDownBox)" .../>
</DropDownBodyTemplate>
</DxDropDownBox>
@code {
Customer Value { get; set; }
IEnumerable<object> GridData { get; set; }
string QueryText(DropDownBoxQueryDisplayTextContext arg) {
if(arg.Value is Customer value)
return value.ContactName;
return string.Empty;
}
void GridSelectedDataItemChanged(object item, IDropDownBox dropDownBox) {
Value = item as Customer;
dropDownBox.HideDropDown();
}
}
The DropDown Box' value is not limited to a single object. It can be a
collection of objects (for those looking to implement a multi-selection editor):
Or even a composite data item generated based on user selection made within the
popup:
Online Demo
NEW FILE INPUT
Our new Blazor File Input component allows you to introduce file upload
functionality to your Blazor app without creating a separate Web API project
with an upload controller.
Our Blazor File Input control supports multiple upload modes (Instant and
OnButtonClick), can upload multiple files simultaneously, and allows you to
validate file size and extension both on the client and server.
Handle the FilesUploading event to upload selected files. For each file, the
event supplies a Stream you can open to read file content. Once the read
operation is complete, you can send the file to another destination, save it to
the file system, or display the file content on a web page.
The following code snippet configures FileInput to upload files to a specified
folder:
* Razor
<DxFileInput FilesUploading="OnFilesUploading" />
@code {
async Task OnFilesUploading(FilesUploadingEventArgs args) {
foreach (var file in args.Files) {
Stream? stream = default;
var filePath = "full path to the uploaded file";
FileStream fs = new(filePath, FileMode.Create);
try {
if(IsValidFile(file)) {
stream = file.OpenReadStream(int.MaxValue);
await stream.CopyToAsync(fs);
}
}
catch (Exception ex) {
if (file.CancellationTokenSource.IsCancellationRequested)
// Handle the cancel action here
}
finally {
await fs.FlushAsync();
fs.Close();
if (stream != null)
stream.Close();
}
}
}
}
Note: Before adding file upload capabilities to your Blazor app, make certain to
institute necessary security-related processes (to avoid risks and control
unauthorized file operations).
Online Demo
NEW DRAWER
Our new Blazor Drawer component allows you to add a "dismissible" navigation
side panel to your web application. The control includes the following features:
* Left-side and right-side position.
* Overlap and shrink display modes.
* The minimized drawer state.
* Header, body, and footer templates.
Online Demo
NEW TOAST
Our new Blazor Toast component allows you to notify users about processes and
events. Notification messages can remain visible until a user clicks the close
button or closed automatically after a predetermined amount of time. The
DevExpress Blazor Toast component supports four theme modes (Dark, Light,
Pastel, and Saturated) and the following notification styles:
* Danger
* Info
* Primary
* Success
* Warning
You can place a DxToast component in markup and call the Show method to display
it.
* Razor
<DxToastProvider Name="ToastContainer" />
<DxToast @ref=toast Text="The process has been completed." ProviderName="ToastContainer" />
@code {
DxToast toast;
protected override void OnAfterRender(bool firstRender) {
toast.Show();
}
}
</lang>
</code2>
<para>
Alternatively, use the notification service to create toasts at runtime.
</para>
<code2>
<lang brush="razor" name="Razor">
<DxToastProvider Name="ToastContainer" />
@code {
[Inject] IToastNotificationService ToastService { get; set; }
protected override void OnAfterRender(bool firstRender) {
ToastService.ShowToast(new ToastOptions {
ProviderName = "ToastContainer",
Text = "The process has been completed."
});
}
}
In both instances, you must add the DxToastProvider component to a page. This
component serves as a toast container and should be declared where toasts will
be displayed.
Online Demo
NEW PROGRESS BAR
The new DevExpress Blazor Progress Bar component allows you to communicate the
status of ongoing processes with end-users. When progress cannot be estimated,
the component can display an infinite moving bar. The control includes the
following integrated features:
* Horizontal, vertical, and circular layout
* Four statuses to indicate process state: InProgress, Warning, Error, and
Success
* Indeterminate state
* Element customization: icon, label, and bar thickness
Online Demo
NEW BAR GAUGE
The Bar Gauge for Blazor allows you to display data as circular bars where each
bar indicates a single value. The component ships with the following
capabilities:
* Geometry and layout configuration
* Palette customization
* Export and printing support
* Real-time data updates
* Gauge element customization: labels, tooltips, legend, and many more.
Online Demo
NEW SPARKLINE
Our new Blazor Sparkline component allows you to display value trends using a
compact UI metaphor. You can use the DevExpress Blazor Sparkline as a standalone
component or embed it into other UI controls. Sparkline allows you to configure
all series and point settings at the root component level. Sparkline applies
corresponding settings based on the Type property value (which defines series
type). In addition to series and point settings, you can configure tooltips and
customize the component's container.
Sparkline includes built-in export and print capabilities. You can call the
ExportToAsync method to export data to a file (PNG, PDF, JPEG, or SVG) or call
the GetSvgMarkup method to obtain the component's SVG markup.
Online Demo
NEW RENDERING ENGINE
The following DevExpress Blazor components now use our optimized rendering
engine (instead of Bootstrap):
* Charts
* Rich Text Editor
* Scheduler
* Pivot Grid
* Upload

KEYBOARD SUPPORT
To address accessibility standards and improve user experiences for those with
disabilities, v24.1 adds keyboard navigation support for the following Blazor UI
components:
* Date Edit
* Time Edit
* Tree View
* Accordion
* ComboBox
* List Box
* TagBox
* Rich Text Editor
* Upload
* Report Viewer
PROJECT TEMPLATES
#.NET 8 AUTHENTICATION AND AUTHORIZATION
Our Blazor project templates for .NET 8 include an option to add ASP.NET Core
Identity and Token-based Authentication to your projects. In addition to the
necessary infrastructure, our templates generate an authentication interface
powered by DevExpress Blazor components.
GRID
#HEADER BANDS
The DevExpress Blazor Grid can now arrange its columns into logical groups
called bands. Each band contains its own header displayed above column headers.
Columns without a band span the entire band region. The Grid also supports
multi-level bands wherein a band can display other bands within it.
Documentation
While end-users can reorder columns within bands or move them to the Group
Panel, column movement between bands is restricted.
The Grid’s Column Chooser has also been updated to support Header Bands. It
displays bands and columns hierarchically and allows end-users to toggle the
visibility of entire groups, not just individual columns.
Online Demo
#EXPORT SERVER-SIDE DATA
v24.1 introduces Blazor Grid data export functionality for any supported
server-side data/Server Mode sources (GridDevExtremeDataSource, or
CustomDataSource). Remote data can be exported to XLS, XLSX, and CSV formats.
The DevExpress Blazor Grid can now fetch records from a remote data source
to/from the exported document. While fetching records, the Grid displays a
loading indicator. To avoid flickering, the indicator is displayed only during
estimated fetch time. For more information on this feature, refer to the
following help topic: Data Export.
Online Demo
#NEW CELL EDITOR APPEARANCE
In-place editors in the filter row, edit row, and edit cells of the DevExpress
Blazor Grid ship with a new improved look/feel - and automatically display
validation icons, when required. The appearance of grid cells is now consistent
in both display and edit modes.
v23.2v24.1
Online Demo
#CELL EDITING ENHANCEMENTS
Our Blazor Grid's Edit Cell mode feature is now official and includes Virtual
Scrolling support. It now ships with the following enhancements:
* Users can now change a check box value with a single click.
* The Grid automatically selects cell text when the cell switches to edit mode.
* The Grid now automatically updates the focused row when switching to edit
mode.
* The Grid’s new GetEditContext method allows you to obtain edit context at any
time.
* Column text alignment affects editors displayed inside the column.
#KEYBOARD NAVIGATION ENHANCEMENTS AND NEW TAB NAVIGATION
In v24.1, our Blazor Grid ships with enhanced keyboard navigation and virtual
scrolling support. The Grid component now automatically activates keyboard
navigation and built-in shortcuts (Note: You may want to remove the
KeyboardNavigationEnabled property from your project as it's now obsolete).
The Tab key navigates between all Grid cells regardless of a cell editor's
active state. Users can also leave the table area by pressing Ctrl + Up or Ctrl
+ Down (Alt + Up or Alt + Down on Mac).
In addition, we improved the RowClick event. With v24.1, this event allows you
to implement custom actions in response to mouse clicks and after a user presses
Enter when a data row has focus.
#BUILT-IN VALUE POSTING
We added the following new method to EditModelSaving event arguments:
CopyChangesToDataItem. This method allows you to copy all changes made to the
edit model during editing. Complex field values can be copied as well.
The following v23.2 code snippet...
* C#
async Task OnEditModelSaving(GridEditModelSavingEventArgs e) {
var editModel = (EmployeeEditModel)e.EditModel;
if (dataItem != null) {
dataItem.FirstName = editModel.FirstName;
dataItem.LastName = editModel.LastName;
dataItem.Title = editModel.Title;
dataItem.HireDate = editModel.HireDate;
}
}
... can now be replaced with a shorter version:
* C#
async Task OnEditModelSaving(GridEditModelSavingEventArgs e) {
var editModel = (EmployeeEditModel)e.EditModel;
if (dataItem != null) {
e.CopyChangesToDataItem();
}
}
#DATEONLY AND TIMEONLY SUPPORT
With v24.1, our Blazor Grid component supports DateOnly and TimeOnly types for
the following:
* Sorting
* Filtering
* Hierarchical Filter Menu for DateOnly values
* Grouping
* Summaries
* Auto-generated cell editors
* Interval grouping for DateOnly values
* Value formatting using DisplayFormat
* Excel Export
#ENABLE/DISABLE SKELETONS
The DevExpress Blazor Grid no longer displays skeletons by default when Virtual
Scrolling is used with local data. Since rows in a local data source are usually
rendered quickly, this new behavior produces a more fluid experience, with fewer
visual updates.
Skeletons are still enabled by default for remote data sources (for record
loading from a server or database). You can now use the SkeletonRowsEnabled
property to control skeleton behavior - enable it for local sources or disable
it for remote sources if server response time is acceptable.
#HIGHLIGHT ROWS ON HOVER
To highlight Blazor Grid rows when hovering rows, simply enable our new
HighlightRowOnHover property (highlight color is based on the theme used within
your DevExpress-powered Blazor app).
CHARTS
#ANNOTATIONS
The new Blazor DxChartAnnotation object allows you to create chart annotations —
comments that contain information about chart content. You can populate
annotations with image or text content. You can also anchor annotations to chart
elements (series points or axes) or position annotations based on pixel
coordinates. DevExpress Blazor Chart components also allow you to customize
annotations as needed — you can configure annotation borders and shadows, image
and text settings.
Online Demo
#STRIPS
Our new Blazor DxChartAxisStrip object allows you to create and configure axis
strips. You can use a strip to highlight a range between two axis values or an
area above/below a value. These highlighted areas help users determine whether a
point falls in or out of a predefined range. You can also add a
DxChartAxisStripLabel object to strip markup to display and configure strip
labels.
Online Demo
#ERROR BARS
The new DxChartSeriesValueErrorBar object allows you to configure error bars
(indicate measurement precision or uncertainty). They display a possible value
range next to a series point. Error bars can display fixed values or
percentages, statistical function values, or error values obtained from data
source fields.
Online Demo
#TOOLTIP ENHANCEMENTS
v24.1 introduces extended tooltip functionality for DevExpress Blazor Chart
components. You can now change tooltip visibility for individual series points
in code. To display a tooltip for a particular series point, call
component-specific ShowTooltip method overloads (DxChart.ShowTooltip,
DxPieChart.ShowTooltip, or DxPolarChart.ShowTooltip). To hide the tooltip, call
the HideTooltip method.
With v24.1, you can also handle the TooltipShowing event to obtain information
about a tooltip before it appears (or cancel the tooltip as needed).
#LABEL CUSTOMIZATION ENHANCEMENTS
We expanded the list of available label customization settings. You can now set
individual text for each point label using the Texts property. Moreover, you can
modify the following properties for point labels:
* Alignment
* HorizontalOffset
* VerticalOffset
* RotationAngle
* ShowForZeroValues
* Font
* Border
#LIVE UPDATE ENHANCEMENTS
We extended our Blazor Chart’s live update capabilities and introduced Length
and VisualRangeUpdateMode properties. These enhancements allow the chart to
retain its visual state (zoom and scroll position) when Chart data changes.
Online Demo
#API ENHANCEMENTS
PieChart settings:
* SegmentDirection - Specifies the direction in which the chart arranges series
slices.
* StartAngle - Specifies the angle at which the chart positions the first
series slice.
Axis settings:
* WorkdaysOnly - Specifies whether the chart displays only workdays on the
axis.
* WorkWeek - Specifies weekdays DxChart treats as workdays.
* WorkDates - Specifies dates DxChart treats as workdays.
* Holidays - Specifies dates DxChart marks as holidays.
Axis Range settings:
* Length - Specifies range length.
* MinVisualRangeLength - Specifies the minimum length of the visual range.
* VisualRangeUpdateMode - Specifies how the visual range behaves if new points
are added to the data source.
NEW COMBOBOX AND TAGBOX
We've rebuilt the DevExpress Blazor ComboBox and TagBox components, maintaining
their existing API while revamping visual and data layers for improved
stability, visuals, and performance. These changes form the basis for upcoming
features and enhancements, with many already available in v24.1.
Online Demo: ComboBoxOnline Demo: TagBox
#PERFORMANCE ENHANCEMENTS
Overall ComboBox and TagBox performance has been improved significantly. Tasks
like opening the dropdown, searching, or navigating through items are now more
responsive. In addition, startup times for ComboBox/TagBox have been reduced by
up to three times. This boosts overall performance for forms that contain these
editors and any components utilizing ComboBox/TagBox internally, such as our
Blazor Grid, Rich Text Editor, Scheduler, and Toolbar.
#SEARCH ACROSS MULTIPLE COLUMNS
Based on customer feedback, our ComboBox and TagBox can now search for text in
any defined column, even columns whose values are not displayed in the edit box.
Use the new SearchEnabled property to exclude specific columns from search when
necessary.
#NEW SEARCH API
In addition to `Contains` and `StartsWith`, ComboBox and TagBox include an
`Equals` condition for searching within collections of similarly named items.
The new SearchTextParseMode property also defines how editors interpret search
strings divided by spaces:
* GroupWordsByAnd – search words are treated as individual conditions grouped
by the AND logical operator; only items that match all of the words are
displayed.
* GroupWordsByOr – search words are treated as individual conditions grouped by
the OR logical operator; items that match at least one of these words are
displayed.
* ExactMatch – search words are not treated separately; only items that match
search text (exact match) are displayed.
#NEW TEMPLATES
We've introduced new templates for ComboBox and TagBox to simplify popular
customization usage scenarios:
* ColumnCellDisplayTemplate – allows you to implement custom formatting for
values in a multi-column ComboBox/TagBox.
* ItemDisplayTemplate/TagDisplayTemplate – these templates are similar to
ItemTemplate/TagTemplate (available previously), but offer information about
the underlying data item, value, and displayed text in context.
* EmptyDataAreaTemplate – allows you to customize the area displayed when the
ComboBox/TagBox popup displays no items.
#KEYBOARD NAVIGATION ENHANCEMENTS
Both ComboBox and TagBox now use a client-side keyboard navigation engine in
their dropdowns. This makes keyboard navigation more responsive in Blazor Server
apps since each keystroke doesn’t need to be sent to the server. In addition,
keyboard navigation is now more stable when used in combination with Virtual
Scrolling.
LIST BOX
#NEW SEARCH AND FILTER API
The DevExpress Blazor List Box introduces new API that allows you to connect it
to external search/filter UI elements:
* SearchText – specifies text used by the List Box to filter and highlight
search results.
* SearchTextParseMode – specifies how the List Box interprets search strings
divided by spaces.
* SetFilterCriteria/GetFilterCriteria/ClearFilter – allows you to apply filters
(of any complexity) using the CriteriaOperator language.
Documentation
Online Demo
#NEW SCROLL API
The following new APIs allow you to scroll to a specific ListBox item:
* MakeItemVisible – scrolls to an item with a specified visible index.
* MakeDataItemVisibleAsync – finds a data item in the list and scrolls to it.
DATE EDIT & TIME EDIT
#DATEONLY AND TIMEONLY SUPPORT
DevExpress Blazor Date Edit and Time Edit components now support DateOnly and
TimeOnly values, respectively. All editor features - including masks, formatting
API, and validation - now function properly with these new data types.
FILE MANAGEMENT
#NEW UPLOAD APPEARANCE
Our Blazor Upload component's file list ships with a revamped look and feel. To
make the list more understandable and visually compact, we removed the common
progress bar, resized and rearranged UI elements, updated icons, and added text
to certain action buttons.
v23.2v24.1

#HTML EXPORT/IMPORT
The DevExpress Rich Text Editor for Blazor now supports document import/export
in HTML format. You can add HTML markup to the main sub-document (AddHtmlAsync
method overloads), obtain HTML text and markup of the main sub-document
(GetHtmlAsync method overloads), and download document content to a file in HTML
format.
Online Demo
#CONTEXT MENU CUSTOMIZATION
v24.1 introduces extended UI customization options for the DevExpress Blazor
Rich Text Editor. You can now customize the component's context menu and
associated sub-menus. Handle the CustomizeContextMenu event to:
* Add or remove built-in menu items
* Add custom menu items
* Customize item appearance/behavior.
With v24.1, you can also control context menu visibility using the
ContextMenuEnabled property.
* Razor
<DxRichEdit CustomizeContextMenu=OnCustomizeContextMenu />
@code {
void OnCustomizeContextMenu(IContextMenuItemCollection items) {
if (selection.Intervals[0].Length > 0) {
var span = await selection.ActiveSubDocument.GetTextSpanAsync(selection.Intervals[0]);
textToSearch = span.Text.Trim();
}
else
textToSearch = null;
var searchItem = items.AddCustomItem(0, "Google Search...", async () => {
var url = String.Format("https://www.google.com/search?q={0}", HttpUtility.UrlEncode(textToSearch));
await JSRuntime.InvokeVoidAsync("open", url, "_blank");
});
searchItem.Enabled = !string.IsNullOrEmpty(textToSearch);
searchItem.IconCssClass = "search-icon";
items.Remove(RichEditContextMenuItemNames.CutSelection);
items.Remove(RichEditContextMenuItemNames.CopySelection);
items.Remove(RichEditContextMenuItemNames.Paste);
var clipboardItem = items.AddCustomItem(1, "Clipboard");
clipboardItem.BeginGroup = true;
clipboardItem.Items.Add(RichEditContextMenuItemNames.CutSelection);
clipboardItem.Items.Add(RichEditContextMenuItemNames.CopySelection);
clipboardItem.Items.Add(RichEditContextMenuItemNames.Paste);
}
}
SCHEDULER
#MULTIPLE RESOURCES
Our Blazor Scheduler allows users to assign multiple resources to an
appointment. With v24,1, users can create meetings with multiple participants,
group events, or services that require coordination among multiple resources. To
enable this functionality, use the EnableMultipleResources property. Once
enabled, appointment forms will allow multiple selection in the Resource field:
All selected resources will be displayed in the appointment tooltip:
If the Scheduler is grouped by resources, multi-resource appointments will
appear under all selected resources.
Online Demo
#BUILT-IN SCROLL BARS
The DevExpress Blazor Scheduler component now automatically displays a scroll
bar when cells don't fit within control boundaries/size. To specify Scheduler
boundaries/size, modify width/height parameters using CSS:
* Razor
<style>
.my-scheduler {
height: 600px;
}
</style>
<DxScheduler ... CssClass="my-scheduler"/>
#SCROLL API
v24.1 ships with a new ScrollTo() method. This method scrolls the view area to a
specified date or appointment. When used, ScrollTo() can help you focus user
attention on the most important time/appointment/event within the currently
displayed view (for example, the beginning of a work day).
* Razor
<DxScheduler ... @ref="Scheduler" />
@code {
DxScheduler Scheduler { get; set; }
DesiredDate = new DateTime(2024, 05, 14)
// ...
protected override void OnAfterRender(bool firstRender) {
base.OnAfterRender(firstRender);
if (firstRender) {
Scheduler.ScrollTo(DesiredDate);
}
}
}
#RECURRENCE FORM CUSTOMIZATION
We enhanced the Scheduler's AppointmentFormShowing event. It now allows you to
customize recurrence options for both Appointment and Recurrence forms. For
instance, you can modify the list of items available in the Appointment form’s
Repeat section as needs dictate:
...Or modify the list of repeat end items and weekday list in the Recurrence
form:
The following code snippet customizes the Scheduler's recurrence options:
* Razor
<DxScheduler ... AppointmentFormShowing="OnAppointmentFormShowing"/>
void OnAppointmentFormShowing(SchedulerAppointmentFormEventArgs args) {
args.FormInfo.RepeatItems = new List<SchedulerRecurrenceType>() {
SchedulerRecurrenceType.Yearly,
SchedulerRecurrenceType.Weekly,
SchedulerRecurrenceType.Never
};
args.FormInfo.RecurrenceFormInfo.RepeatEndItems = new List<SchedulerRecurrenceRange>() {
SchedulerRecurrenceRange.OccurrenceCount,
SchedulerRecurrenceRange.EndByDate
};
args.FormInfo.RecurrenceFormInfo.WeekDayItems.Remove(SchedulerWeekDays.WeekendDays);
}
}
#DAY, WEEK, WORKWEEK VIEWS – MINIMUM CELL WIDTH
You can now specify the minimum width of a day cell in day, week, and work week
views. Pass the integer value to the CellMinWidth property to set this width in
pixels.
WINDOW AND POPUP

#NATIVE REACT REPORT VIEWER COMPONENT
Our native React Report Viewer component leverages the internal architecture of
the DevExpress Angular Report Viewer and associated assistive technologies. Our
implementation delivers superior user experiences and improved performance when
compared to solutions based on JavaScript wrappers. Our new React Report Viewer
ships with the following built-in customization capabilities:
Toolbar Customization
* JavaScript
'use client';
import React from 'react';
import ReportViewer, { Callbacks, RequestSettings } from 'devexpress-reporting-react/dx-report-viewer';
import { TemplateEngine } from 'devexpress-reporting-react/dx-report-viewer/core/template-engine';
import { ActionId } from 'devexpress-reporting/viewer/constants';
import { CustomAction } from 'devexpress-reporting/dx-webdocumentviewer';
import "devextreme/dist/css/dx.light.css";
import "@devexpress/analytics-core/dist/css/dx-analytics.common.css";
import "@devexpress/analytics-core/dist/css/dx-analytics.light.css";
import "devexpress-reporting/dist/css/dx-webdocumentviewer.css";
import styles from "./page.module.css";
export default function Home() {
<!--don't remove this line/comment-->
const templateEngine = new TemplateEngine();
templateEngine.setTemplate('slideshow', () => (
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" x="0px" y="0px" viewBox="0 0 24 24">
<polygon className="dxd-icon-fill" points="4,2 4,22 22,12 " />
</svg>
));
const handleCustomizeMenuActions = ({ sender, args }: { sender: any, args: any }) => {
let interval: any;
const action = new CustomAction({
text: "Run Slide Show",
imageTemplateName: "slideshow",
visible: true,
disabled: false,
selected: false,
clickAction: function () {
if (this.selected) {
clearInterval(interval);
this.selected = false;
return;
}
var model = sender.GetPreviewModel();
if (model) {
this.selected = true;
interval = setInterval(function () {
var pageIndex = model.GetCurrentPageIndex();
model.GoToPage(pageIndex + 1);
}, 2000);
}
}
});
args.Actions.push(action);
var highlightEditingFieldsAction = args.GetById(ActionId.HighlightEditingFields);
if (highlightEditingFieldsAction)
highlightEditingFieldsAction.visible = false;
};
return (
<main className={styles.main}>
<ReportViewer reportUrl="Report" templateEngine={templateEngine}>
<RequestSettings invokeAction="/DXXRDV" host="http://localhost:5065" />
<Callbacks CustomizeMenuActions={React.useCallback(handleCustomizeMenuActions,[])} />
</ReportViewer>
</main>
);
}
Example: Reporting for React - Customize Viewer Toolbar
Parameters Customization
The following sample code declares a custom template for the Parameter Editor
and applies validation rules to the NumberBox component (used to edit the "Age"
report parameter value):
* JavaScript
const CustomizeParameterEditor = ({data}: {data: IEditorViewModel}) => (
<NumberBox showSpinButtons={true} value={data.value} disabled={data.disabled}>
<Validator validationRules={data.validationRules}>
</Validator>
</NumberBox>
);
export default function Home() {
const templateEngine = new TemplateEngine();
templateEngine.setTemplate('custom-parameter-editor', CustomizeParameterEditor);
const handleCustomizeParameterEditors = React.useCallback((event: any): void => {
const parameter = event.args.parameter;
const info = event.args.info;
const curYear = new Date().getFullYear();
if (parameter.type === 'CustomParameterType') {
info.validationRules = info.validationRules || [];
info.validationRules.push({
type: 'range',
min: 1900,
max: curYear,
message: `The Birth Year parameter value should be in a range from 1900 to ${curYear}.`
});
info.editor.header = "custom-parameter-editor";
}
}, []);
return (
<main className={styles.main}>
<ReportViewer reportUrl="CustomParameterReport" templateEngine={templateEngine}>
<RequestSettings invokeAction="/DXXRDV" host="http://localhost:2119/" />
<Callbacks CustomizeParameterEditors={handleCustomizeParameterEditors} />
</ReportViewer>
</main>
);
}
Documentation: Create a React Application with Web Document Viewer (Next.js)
#NATIVE ANGULAR REPORT VIEWER
Toolbar Customization API
With this release, our Angular Report Viewer allows you to customize its
built-in toolbar as requirements dictate. The following code snippet hides a
toolbar item using the CustomizeMenuActions event handler:
*
CustomizeMenuActions(event) {
var actionSearch = event.args.GetById(ActionId.Search);
if (actionSearch)
actionSearch.visible = false;
}
var highlightEditingFieldsAction = e.GetById(DevExpress.Reporting.Viewer.ActionId.HighlightEditingFields);
if (highlightEditingFieldsAction)
highlightEditingFieldsAction.visible = false;
}
The following code snippet adds a custom export option to the toolbar using the
same event handler:
*
function CustomizeMenuActions(event) {
const actionExportTo = event.args.GetById(ActionId.ExportTo);
const newFormat = { format: 'NewFormat', text: 'New Format' };
if (actionExportTo) {
actionExportTo.events.on('propertyChanged', (args) => {
const formats = actionExportTo.items[0].items;
if (args.propertyName === 'items' && formats.indexOf(newFormat) === -1) {
formats.push(newFormat);
}
});
}
}
OnPush Change Detection Strategy Support
v24.1 also adds support for OnPush Change Detection Strategy. Angular's OnPush
change detection strategy improves performance by reducing unnecessary rendering
cycles and only triggering change detection when input references change. With
this update, you can change the detection strategy from default to
ChangeDetectionStrategy.OnPush by adding the changeDetection property in the
@Component decorator as follows:
*
import { Component, ViewEncapsulation } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';
import { DxReportViewerModule } from 'devexpress-reporting-angular';
@Component ({
selector: 'app-root',
changeDetection: ChangeDetectionStrategy.OnPush,
encapsulation: ViewEncapsulation.None,
standalone: true,
imports: [
CommonModule,
RouterOutlet,
DxReportViewerModule
],
templateUrl: './app.component.html',
styleUrls: [...]
})
export class AppComponent {
title = 'DXReportViewerSample';
reportUrl: string = 'TestReport';
hostUrl: string = 'https://localhost:5001/';
invokeAction: string = '/DXXRDV';
}
#NEW STANDALONE PARAMETERS PANEL COMPONENT FOR ASP.NET CORE, BLAZOR, ANGULAR
Our new Report Parameters Panel component automatically generates a layout for
report parameter editors (including associated grouping) based on a report
instance supplied from the backend.
This component addresses a variety of usage scenarios, including the need to
programmatically create a report and export it or send it by mail - without
displaying its print preview to an end-user. Our Standalone Parameters Panel
helps reduce an app’s overall memory footprint because it eliminates the need to
generate report images in the background and send them to a client app.
Component implementation is based on the Parameters Panel in our Report Viewer
component. As such, it gives you access to the same set of component public
properties and events related to report parameters. Here's a sample component
definition for the Angular platform:
*
<dx-report-parameters-panel class="parametersPanel" [reportUrl]="yourReportName" height="560px" width="400px">
<dxrpp-request-options [invokeAction]="invokeAction" host="http://yourhostname:port/"></dxrpp-request-options>
<dxrpp-callbacks (BeforeRender)="onBeforeRender($event)"></dxrpp-callbacks>
</dx-report-parameters-panel>
The panel allows you to create custom submit buttons and handle associated click
events. This will give you the ability to serialize input parameter values, send
them to the backend app, and then apply them to an instance of the XtraReport
class (before printing or export operations):
*
onBeforeRender(event) {
this.sender = event.sender;
const panel = this.sender.GetParametersModel();
panel.buttons.push({
text: 'Export',
onClick: async () => {
const data = this.sender.SerializeParametersState();
const formData = new FormData();
formData.append('serializedParameters', data);
formData.append('reportUrl', this.reportUrl);
const result = await fetch(`${this.host}/ExportWithParameters`, {
method: 'POST',
body: formData
}).then(response => response.json());
alert(result.message);
}
}, {
text: 'Send Email',
onClick: () => {
alert('Email sent');
}
});
panel.showButtons = true;
}
The following code snippet applies parameter values on the backend:
* C#
public async Task<IActionResult> ExportWithParameters(
[FromServices]IReportParametersSerializer reportParametersSerializer,
[FromForm]string serializedParameters,
[FromForm]string reportUrl) {
var report = await reportParametersSerializer.ApplyParametersStateAsync(reportUrl, serializedParameters);
report.ExportToPdf("yourFilePath");
return Ok(new { Message = "A report has been successfully exported" });
}
Example
#WEB REPORT DESIGNER - HIDE/RESTRICT PARAMETER EDITING
We introduced a new set of APIs to help customize edit settings for parameters,
parameter groups, and parameter separators. This API will be of value when
creating a set of "canned" or predefined reports with mandatory/hidden
parameters.
The new ParameterEditingSettings class contains the following settings that
affect the Properties Panel, Field List and Parameter Editor:
* AllowEditParameterCollection - Hides parameter add and delete buttons.
* AllowEditParameterGroups - Hides parameter group add and delete buttons.
* AllowEditParameterSeparators - Hides parameter separator add and delete
buttons.
* AllowEditProperties - Disables properties editors for parameter and groups.
* AllowReorderParameters - Hides the up and down buttons and disables
drag-n-drop operations.
The following code snippet turns parameters, parameter groups and separators to
read-only for an ASP.NET Core application (users can't add/delete
parameters/groups/separators, edit/reorder associated properties):
* Razor
@{
var designerRender = Html.DevExpress().ReportDesigner("reportDesigner")
.ParameterEditingSettings( configure => {
configure.AllowEditParameterCollection = false;
configure.AllowEditParameterSeparators = false;
configure.AllowEditParameterGroups = false;
configure.AllowEditProperties = false;
configure.AllowReorderParameters = false })
.Height("100%")
.Bind("TestReport");
@designerRender.RenderHtml()
}
We also introduced a new CustomizeParameterProperties event that allows you to
customize a specific parameter or disable/hide specific properties editors at
the web Report Designer level.
For instance, the following code snippet hides the Allow Null Value property
editor for all parameters (both in the Properties Panel and Parameter Editor)
and hides the delete button for parameter groups:
*
function customizeParameterProperties(s, e) {
if (e.parameter) {
let allowNullInfo = e.getEditor('allowNull');
if (allowNullInfo) {
allowNullInfo.visible = false;
}
}
if (e.parameterPanelLayoutItem.layoutItemType === 'Group') {
e.editOptions.allowDelete = false;
}
}

REPORTING FOR BLAZOR
#REPORT VIEWER - SEND AN EMAIL
We created an example that uses the Mailkit library to send an email from our
Native Blazor Report Viewer.
The "Send Email" button in the Viewer's toolbar opens a DxPopup. In the "Send
Email" window, you can specify a recipient list, subject, attachment, and body.
Click the "Send" button to send the report with the specified settings.
* The DxPopup component is available in ASP.NET & Blazor Subscription.

ALL PLATFORMS
#SVG EXPORT
v24.1 ships with a new SVG export option. When enabled, it allows users to save
reports as a collection of scalable vector graphics (SVG) images. This new
export format will produce high-quality vector report page images without loss
of text content quality. SVG export will be of value for those who wish to
modify/share report images or embed report thumbnails on web pages (since the
SVG format is fully compatible with modern browsers).
Export to PNGExport to SVG
Open SVG file (Export Result)
#NEW EXPRESSION FUNCTIONS
We added the following new expression functions to criteria language syntax used
in DevExpress Reports:
* PrevRowColumnValue(string columnName) — Allows users to retrieve the value of
the previous column/row. The function call returns the same record if it is
the first record in the data source.
* NextRowColumnValue(string columnName) — Allows users to retrieve the value of
the next column/row. The function call returns the same record if it is the
latest record in the data source.
* GroupIndex(int level) — Allows users to retrieve the current group index.
* CurrentRowIndexInGroup() — Allows users to retrieve the current row index
within a group.
Functions are applicable to report control properties whose values can be set
via expression binding. They are especially useful when you need to hide first
or last records within a group, or highlight these records (i.e., modify
appearance properties like Font, BackColor, etc.). Obtaining the group index or
the row index within a group is helpful when you need to display group numbering
in the group header or record numbering within the group itself. The
introduction of PrevRowColumnValue and NextRowColumnValue functions also
simplifies migration from Microsoft SSRS and Crystal Reports, where their
counterparts exist.
The following example generates a report with a multi-level numbered list. To
achieve this report layout, report controls use GroupIndex and
CurrentRowIndexInGroup functions within data binding expressions (to return
group and row indexes).
The following image illustrates output for a report designed to group
information by product category and discontinued state (Review the following
help topic for more information: Group Numbering by Index.):

#PARAMETERS LOCALIZATION ENHANCEMENTS
With our built-in DevExpress Reports localization engine, individuals using our
Report Designer can now localize the titles of parameter groups displayed within
the Parameters Panel across all supported platforms.
Descriptions for lookup parameter static values are also localizable.
CLOUD DEPLOYMENT
#SKIA-BASED GRAPHICS ENGINE (NON-WINDOWS ENVIRONMENT) - PERFORMANCE ENHANCEMENTS
We refactored the implementation of our cross-platform drawing engine: we added
caching for font internals and optimized dynamic memory allocation. Our internal
tests indicate the following improvements when generating a 1500-page text-based
report (average of 25 iterations):
* Time taken to create a report document has decreased by approximately 20% (9
sec vs. 11 sec).
* Time taken to export the report to PDF has decreased by approximately 16%
(7.25 sec vs. 8.7 sec).
* Time taken to export the report to an image has decreased by approximately
10% (5.2 sec vs. 5.7 sec).
We also discovered that the overall CPU usage decreased by approximately 8-10%.
Note: Performance enhancements are most pronounced for large report documents
with lots of text.
#MICROSOFT AZURE AND AMAZON WEB SERVICES APP DEPLOYMENT TUTORIALS
We created and published a set of help topics designed to simplify the
deployment of DevExpress Reports-powered web apps to Microsoft Azure and AWS.
Tutorials include:

#REPORTING FOR MICROSOFT AZURE — UPDATED REFERENCES
We have refactored our internal implementation of services responsible for
communicating with the Azure Service Bus and Azure Storage. These services are
designed to host multi-instance ASP.NET Web Forms, MVC, and ASP.NET Core web
apps with DevExpress Reports on Microsoft Azure. They also allow you to cache
report documents in Azure Table and Azure Blob storage. Our implementation now
uses the most recent versions of the following NuGet packages.
* Azure.Data.Tables v12.8.3
* Azure.Storage.Blobs v7.17.4
* Azure.Messaging.ServiceBus v12.19.1

ACCESSIBILITY
We now support assistive tools for the following controls:
* Native Blazor Report Viewer
* JS Report Viewer
* WinForms Report Viewer*
* WPF Report Viewer*
* We are aware of issues and plan to address them in upcoming releases.
We have enhanced the accessibility tree to ensure that assistive technologies
receive the information they require from user interface elements in accordance
with accessibility guidelines outlined in WCAG.
Assistive technologies (screen readers) can now access document content in all
the controls listed above.
The following controls now fully supports keyboard navigation:
* Native Blazor Report Viewer
* HTML5/JS Report Viewer
Users can move through user interface elements and navigate through document
content using tab, arrow and special keys.

#SQLDATASOURCE — POSTGRES DATA DRIVER V7.0 SUPPORT
Initially, we hoped to introduce Postgres Stored Procedure support, but
discovered that they are mostly useful for update and delete database operations
(the SqlDataSource component operates in read-only mode).
Instead, we modified our Postgres Database connection and now allow you to bind
DevExpress Reports and BI Dashboards to Postgres Functions while using the
newest v7.0 database driver.
#JSONDATASOURCE — THE USE OF THE SYSTEM.TEXT.JSON NUGET PACKAGE
With v24.1, DevExpress Reports and BI Dashboard will utilize functionality from
the System.Text.Json assembly/NuGet package (by default). This change was
influenced by security considerations and the improved performance offered by
Microsoft's built-in library. This package is part of .NET, and this change only
pertains to the .NET product line; .NET Framework-based products remain
untouched and will continue to use functionality from the Newtonsoft.Json
package.
If, for any reason, you are unable to utilize System.Text.Json functionality in
your .NET-based application, you can set the
DevExpress.DataAccess.Native.Json.JsonLoaderHelper.JsonProcessingLibrary*
property to NewtonsoftJson and continue using the Newtonsoft.Json library.
* Note: We provide this property for backward compatibility purposes. It will be
removed from source code in future releases once our migration is complete.
We also encourage you to update your applications accordingly.

BUSINESS INTELLIGENCE DASHBOARD V24.1
* Cascading Parameters
* Web Dashboard Enhancements
* Data Sources
CASCADING PARAMETERS
You can now set up cascading parameters to filter the data source or items in a
dashboard. The list of values of a dependent parameter now refreshes
automatically when you change the value of the parent parameter. When using two
parameters, the parent parameter is used to filter the data source for the
dependent parameter with dynamic list settings. The following image illustrates
cascading parameters where Products parameter values are filtered by the
selected Category:
Documentation (WinForms) | Documentation (Web)
WEB DASHBOARD ENHANCEMENTS
#CACHE MANAGEMENT API
This update allows you to tailor our built-in BI Dashboard caching engine.
Customers encountered several scenarios where our built-in cache needed to be
disabled, prompting us to introduce the following API.
You can now use the ASPxDashboard.DataSourceCacheEnabled property for Web Forms
(or the DashboardConfigurator.DataSourceCacheEnabled property for other web
platforms) to disable caching entirely. This forces the DevExpress Dashboard to
load the most relevant data whenever a user accesses and views a dashboard.
By default, whenever a dashboard parameter value changes, a new data source
instance is created and stored in the cache. This impacts memory usage,
especially when a parameter doesn't affect data source filtering. As such, we
added the ASPxDashboard.DataSourceCacheKeyCreated/
DashboardConfigurator.DataSourceCacheKeyCreated event to prevent the creation of
new cache records based on parameter values/available event arguments. For
instance, consider the following:
* C#
DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
if(e.Key.DashboardId == "MyDashboard")
e.Key.Parameters.Clear();
};
In this scenario, altering a parameter value updates dashboard item data, while
reusing the existing data source from the cache without additional fill
requests.
Furthermore, you can utilize this event to update a specific data source when
any interaction with the dashboard takes place:
* C#
DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
if(e.Key.DataSourceId == "dsSales")
e.InvalidateCacheRecord();
};
Another use case involves increasing cache key granularity by including groups
of users or the users themselves in the cache key. You can utilize the new
IDataSourceCacheKey.CustomData property for this purpose. The primary advantage
of this strategy is that the key is solely used for creating/retrieving records
from the cache and is never exposed on the client side, thus maintaining the
security aspect of the implementation:
* C#
DashboardConfigurator.Default.DataSourceCacheKeyCreated += (s, e) => {
e.Key.CustomData.Add("UserId", CurrentUser.UserId);
};
#ACCESSIBILITY — KEYBOARD NAVIGATION
Keyboard navigation is fully supported for groups and dashboard items. Users can

OFFICE FILE API V24.1
Your feedback matters.
Please, review the description of DevExpress Office File API-related features
below and leave your feedback at the end of the section.
Go to the survey now.
ACCESSIBILITY ENHANCEMENTS
We extended accessibility-related support to the following elements when
exporting Word documents to accessible PDF files:
* Table of Contents tagging
* Metadata fields
* Alt text handling
* Tables
* Floating objects
Adobe Acrobat Pro and PDF Accessibility Checker 2024 were used for quality
control. Our test documents successfully passed validation for PDF/UA
compatibility and WCAG 2.1 compliance.
Accessibility-related export enhancements are available out-of-the-box when you
specify the PdfUACompatibility option:
* C#
using System.IO;
using DevExpress.XtraRichEdit;
// ...
RichEditDocumentServer wordProcessor = new RichEditDocumentServer();
//...
using(FileStream stream =
new FileStream(resultFilePath, FileMode.Create, FileAccess.Write, FileShare.Read)) {
PdfExportOptions exportOptions = new PdfExportOptions();
exportOptions.PdfUACompatibility = PdfUACompatibility.PdfUA1;
wordProcessor.ExportToPdf(stream, exportOptions);
}
In addition, we added a Decorative property for both Word Processing Shape and
Spreadsheet Shape classes to mark document graphics (pictures, shapes, and
charts) as decorative. Decorative shapes add visual interest, but they are not
informative. Thus, you do not need to specify Alt Text (meaningful description)
for decorative objects when you generate an accessible document.
PRINTING ON UNIX-BASED SYSTEMS
In this release (v24.1), we added printing support for .NET-based Office File
API powered applications running on Unix-based systems. You can now print
barcodes, and Word, Excel, and PDF documents in non-Windows environments.
We created a new set of APIs that work with the DXPrinterSettings options
available in our DevExpress.Drawing library.
Use the following new methods to print your documents and barcodes on Unix-based
systems:
* C#
// DevExpress.XtraRichEdit.RichEditDocumentServer:
public void Print(DXPrinterSettings printerSettings, string printDocumentName);
public void Print(DXPrinterSettings printerSettings);
//DevExpress.Spreadsheet.Workbook:
public void Print(DXPrinterSettings printerSettings);
public void Print(DXPrinterSettings printerSettings, params string[] sheetNames);
public void Print(DXPrinterSettings printerSettings, IEnumerable<string> sheetNames);
//DevExpress.BarCodes.BarCode:
public void Print(DXPrinterSettings printerSettings);
For the DevExpress.Pdf.PdfDocumentProcessor class, you still need to call the
current Print(PdfPrinterSettings printerSettings) method. To modify print
settings, use the new PdfPrinterSettings.DXPrinterSettings option as follows:
* C#
using DevExpress.Drawing.Printing;
using DevExpress.Pdf;
// Load a PDF file
PdfDocumentProcessor documentProcessor = new PdfDocumentProcessor();
documentProcessor.LoadDocument(@"..\..\Demo.pdf");
// Declare printer settings
PdfPrinterSettings pdfPrinterSettings = new PdfPrinterSettings();
// Specify CUPS printer settings
DXPrinterSettings dxPrinterSettings = pdfPrinterSettings.DXSettings;
dxPrinterSettings.Duplex = DXDuplexMode.DuplexLongEdge;
dxPrinterSettings.Copies = 3;
// Print the document
documentProcessor.Print(pdfPrinterSettings);
Note: For Unix-based systems, you need to install the libcups2 package
separately.
EXPORT DOCUMENTS TO SVG
We extended our image export engine and now support SVG images within our
Barcode Generation API, Word Processing Document API, and Spreadsheet Document
API libraries. With v24.1, you can generate SVG images from your Barcodes, Word
document pages and Excel worksheets/cell ranges in both Windows and non-Windows
environments.
To generate an SVG image from a barcode, create a BarCode class instance, modify
settings as necessary and call the BarCode.Save method with DXImageFormat.Svg as
a parameter.
* C#
using (BarCode barCode = new BarCode()) {
barCode.Symbology = Symbology.QRCode;
barCode.BackColor = Color.White;
barCode.ForeColor = Color.Black;
barCode.RotationAngle = 0;
barCode.CodeBinaryData = Encoding.Default.GetBytes("https://www.devexpress.com/");
barCode.Options.QRCode.CompactionMode = QRCodeCompactionMode.Byte;
barCode.Options.QRCode.ErrorLevel = QRCodeErrorLevel.Q;
barCode.Options.QRCode.ShowCodeText = false;
barCode.DpiX = 72;
barCode.DpiY = 72;
barCode.Module = 2f;
barCode.Save("barcode.svg", DXImageFormat.Svg);
}
For Word documents, use our new Image Export API - create an
RichEditImageExportOptions instance, specify the target DXImageFormat.Svg format
using the RichEditImageExportOptions.Format property and call the
RichEditDocumentServerExtensions.ExportToImage extension method with the
RichEditImageExportOptions object as a parameter.
* C#
using (var wordProcessor = new RichEditDocumentServer()) {
wordProcessor.LoadDocument(@"C:\Documents\Alice.docx");
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Svg;
options.PageRange = "1";
wordProcessor.Document.ExportToImage("first_page_image.svg", options);
}
To export a cell range in an Excel worksheet to an SVG image, call the
CellRangeExtensions.ExportToImage method with ImageFileFormat.Svg as a
parameter.
* C#
using (Workbook workbook = new Workbook()) {
workbook.LoadDocument("InvestmentPortfolio.xlsx", DevExpress.Spreadsheet.DocumentFormat.Xlsx);
Worksheet worksheet = workbook.Worksheets.ActiveWorksheet;
worksheet.Range["B18:I30"].ExportToImage("cell_range_image.svg", ImageFileFormat.Svg);
}
SPREADSHEET DOCUMENT API
#JUSTIFY & DISTRIBUTED TEXT ALIGNMENT
v24.1 adds support for Justify and Distributed horizontal alignment types within
Spreadsheet cells. Excel files using these alignment options can be printed and
exported to PDF.
You can use the Cell.Alignment.Horizontal property to specify horizontal
alignment in code.
The following code snippet specifies alignment in code:
* C#
var workbook = new Workbook();
var worksheet = workbook.Worksheets[0];
Cell cellA1 = worksheet.Cells["A1"];
cellA1.Value = "Justified and top";
cellA1.Alignment.Horizontal = SpreadsheetHorizontalAlignment.Justify;
cellA1.Alignment.Vertical = SpreadsheetVerticalAlignment.Top;
workbook.ExportToPdf("Result.pdf");
#SORT AND FILTER BY COLOR
The DevExpress Spreadsheet Document API ships with enhanced filter and
sort-related capabilities. We added new APIs that can sort and filter workbook
data by background and font color. Cell ranges filtered/sorted by cell color can
be also printed and exported to PDF.
Our Sorting APIs include new Worksheet.Sort method overloads designed to sort a
specified range by font color or fill setting (background color and pattern).
The following code snippet sorts cell values across two cell ranges - the first
is sorted by a red font color and the second is sorted by fill settings
specified for the first cell in the range:
* C#
workbook.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = workbook.Worksheets.ActiveWorksheet;
// Sort cell range by font color
worksheet.Sort(worksheet["B2:B10"], Color.Red);
// Sort cell range by fill color
worksheet.Sort(worksheet["D2:D10"], worksheet["D2"].Fill);
To filter cells by font or background color, you need to apply an auto-filter to
the required cell range or table. Once complete, you need to obtain the required
column from the AutoFilter.Columns collection and call one of the following
methods:
* AutoFilterColumn.ApplyFillColorFilter(Color)
* AutoFilterColumn.ApplyFillFilter(Fill)
* AutoFilterColumn.ApplyFontColorFilter(Color)
The following code snippet uses these methods for both cell range and table:
* C#
workbook.LoadDocument("sort-filter.xlsx");
Worksheet worksheet = workbook.Worksheets.ActiveWorksheet;
// Apply an auto-filter to a cell range and filter the first column by font color
worksheet.AutoFilter.Apply(worksheet["B1:B10"]);
worksheet.AutoFilter.Columns[0].ApplyFontColorFilter(Color.Red);
// Create a table, apply an auto-filter and filter the first column by fill color
Table table = worksheet.Tables.Add(worksheet["B12:B21"], true);
table.AutoFilter.Apply();
table.AutoFilter.Columns[0].ApplyFillColorFilter(Color.Red);
In addition, our new APIs allow you to sort data across a filtered range (when
auto-filter is enabled) and sort cells by their values/colors simultaneously
(using sorting conditions).
Documentation: Sort Cell Range by Color
PDF DOCUMENT API
#LAYERS API
v24.1 includes an enhanced PDF Facade API and new APIs designed to manage
Optional Content (Layers) visibility in code.
Note: A PDF document only stores a default Optional Content configuration. This
means that Layer visibility is not preserved when you save the document.
Visibility settings are only applicable when you preview the document in the PDF
Viewer component or print the document/export it to an image.
The new API is available via the PdfDocumentFacade.OptionalContentVisibility
property. Access Optional Content groups using the
PdfOptionalContentVisibility.Groups collection. To change group visibility,
modify the PdfOptionalContentGroupVisibility.Visible property value.
The following code snippet changes visibility for Optional Content groups stored
in the document and generates print/image output (to preview results):
* C#
PdfDocumentProcessor processor = new PdfDocumentProcessor();
processor.LoadDocument("layers.pdf");
// Set visibility for each Layer
processor.DocumentFacade.OptionalContentVisibility.Groups[0].Visible = false;
processor.DocumentFacade.OptionalContentVisibility.Groups[1].Visible = false;
processor.DocumentFacade.OptionalContentVisibility.Groups[2].Visible = true;
// Print document or export its page to an image to check the result
DXBitmap bitmap = processor.CreateDXBitmap(1, 1000);
processor.Print();
Documentation: Manage Visibility of Layers (Optional Content Groups)
#PDF-A CONVERTER ENHANCEMENTS
With this release (v24.1), our PdfDocumentConverter can convert your documents
to PDF/A-1b. To create PDF/A-1b documents, pass the PdfCompatibility.PdfA1b
value to the Convert method as a parameter.
* C#
using DevExpress.Pdf;
// ...
var filePath = "PdfAConversionDemo.pdf";
var converter = new PdfDocumentConverter(filePath);
// Convert the file to the Pdf/A1-b format.
converter.Convert(PdfCompatibility.PdfA1b);
converter.SaveDocument("Result.pdf");
We also added PdfDocumentConverter.PdfACompatibility and
PdfDocumentConverter.PdfUACompatibility properties to help obtain the current
PDF/A and PDF/UA versions of the document loaded to the converter.
WORD PROCESSING DOCUMENT API
#MATH EQUATIONS
Our Word Processing tools now preserve Math Equations when saving a document.
You can import your Word documents with Math Equations in our Word Processing
Document API library and save them to the RTF and OpenXml (.docx/.docm) formats
without content loss. Note: Math Equations will be printed or exported to PDF
only if the source document contains a fallback image for a Math Equation. To
suppress Math Equation import, set the DocumentCapabilities.MathEquations
property to DocumentCapability.Disabled.
#CROSS-PLATFORM IMAGE EXPORT API
v24.1 includes new cross-platform APIs to export Word document pages to an
image. This new capability allows you to generate document previews in both
Windows and non-Windows environments. With our new APIs, you can convert
document pages to raster and vector images (PNG, JPEG, BMP, multi-page Tiff,
emf), save them as physical files on the disk or obtain a list of image streams
for further processing in code. You can also set image background color, modify
output image resolution, or generate thumbnail images with a specified size.
The new API is available via the RichEditDocumentServerExtensions.ExportToImage
extension method of the Document object.
Please note that the RichEditDocumentServerExtensions class is defined in the
DevExpress.Docs.v24.1.dll assembly. Add this assembly to your project or install
the "DevExpress.Document.Processor" NuGet Package to use the
RichEditDocumentServerExtensions members. You need a license for the DevExpress
Office File API Subscription or DevExpress Universal Subscription to use this
class in production code.
The following code snippet exports the first document page to an image with a
specified size and JPEG format:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.Export.Image;
using DevExpress.Drawing;
using (var wordProcessor = new RichEditDocumentServer()) {
wordProcessor.LoadDocument(@"C:\Documents\Alice.docx");
RichEditImageExportOptions options = new RichEditImageExportOptions();
options.Format = DXImageFormat.Jpeg;
options.PageRange = "1";
options.LargestEdgeLength = 1080;
wordProcessor.Document.ExportToImage(@"C:\Documents\Image.jpeg", options);
}
#GUTTER AND MIRRORED MARGINS
The DevExpress Word Processing Document API v24.1 allows you to specify gutter
margins - extra space that ensures binding will not obscure text on printed
pages. You can specify gutter position (top, left, and right) and margin size.
Use the Document.GutterAtTop, SectionMargins.GutterPosition, and
SectionMargins.Gutter properties to address specific usage requirements.
The following code snippet adds a left gutter to the first document section:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
using (var wordProcessor = new RichEditDocumentServer()) {
wordProcessor.LoadDocument(@"Documents//Alice.docx");
Document document = wordProcessor.Document;
Section firstSection = wordProcessor.Document.Sections[0];
var pageMargins = firstSection.Margins;
pageMargins.GutterPosition = GutterPosition.Left;
pageMargins.Gutter = Units.InchesToDocumentsF(1);
wordProcessor.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
}
Our new Document.MarginType property allows you to define a regular or mirrored
margin type. Enable mirrored margins if you print on both sides of the paper and
want to bind the printout.
The following code snippet enables mirrored margins and specifies an additional
space value:
* C#
using DevExpress.XtraRichEdit;
using DevExpress.XtraRichEdit.API.Native;
using DevExpress.Office.Utils;
using (var wordProcessor = new RichEditDocumentServer()) {
wordProcessor.LoadDocument(@"Documents//Alice.docx");
Document document = wordProcessor.Document;
// Enable mirrored margins
document.MarginsType = MarginsType.Mirrored;
foreach (Section section in wordProcessor.Document.Sections) {
var pageMargins = section.Margins;
// Set the value for mirrored margins
pageMargins.Gutter = Units.InchesToDocumentsF(0.5f);
}
wordProcessor.SaveDocument("Alice_formatted.docx", DocumentFormat.OpenXml);
}

#MULTI-COLUMN LAYOUT
The DevExxpress .NET MAUI CollectionView now supports multiple items within any
row/column. Our multi-span layout can simplify design if/when collection view
items are displayed as cards (allowing you to display more items on screen).
For more information, please refer to the following API members:
* ItemSpanCount

</ContentPage>
TARGET PLAIN .NET
As you may know, the XUnit testing library requires standard .NET 8 (not .NET
8.0 Android/iOS) to be referenced as a target framework within project settings.
In previous versions, you could not use our controls in a standard .NET 8
project and therefore you could not use XUnit. With v23.2.5, you can target
standard .NET 8 in projects when using DevExpress .NET MAUI component libraries.
Documentation
* XAML
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>

OPTIMIZED MEMORY CONSUMPTION
With this update, DevExpress .NET MAUI components allow you to ship mobile apps
with a significantly lower memory footprint (prevents memory-related issues and
improves overall performance).
BUILD SETTINGS
The DevExpress.Maui.Core NuGet package now includes ".props" and ".targets"
files for default build settings. These settings allow you to maximize
performance and minimize application size across a variety of usage scenarios.
Additionally, they allow you to use Emit as needed (to generate Entity Framework
Core classes dynamically).

BLAZOR – CRUD
#BATCH / CELL EDIT IN GRID LIST EDITOR
Batch Edit support officially ships in XAF Blazor v24.1 via a single option
(InlineEditMode = Batch) - much like its XAF WebForms counterpart.
Roman Shelomanov
We have been testing this since 24.1 EAP and now in 24.1.2 Beta and it works
fantastic. Thank you so much for getting it done, it's one extra step to get
Blazor to feature parity with WinForms that lots of us have used and loved over
the years.
#EXPORT DATA FROM GRID LIST EDITOR TO EXCEL WHEN DATAACCESSMODE = SERVER
Our Blazor Components and XAF v24.1 support Excel export functionality for grids
bound to server-side data (for both EF Core and XPO ORM). To export data to
Excel, the DevExpress Blazor Grid will display a loading indicator and download
all records from a data source.
#ADD NEW FIELDS INTO THE CUSTOMIZATION FORM OF THE GRID AND LAYOUT CONTROLS AT
RUNTIME
XAF WinForms apps include an Object Model dialog. With it, end-users can search,
tick or untick data model fields (including sub-fields and collections), which
are not yet displayed in the grid or layout control (as part of the Column
Chooser or Customization Form).
Much like Microsoft Office apps, this capability allows users to fully customize
list and detail forms (based on the structure of a data model). Again, this is
helpful when developers need to address changes to business requirements without
redeployment. For more information, refer to Runtime Layout Customization in
ASP.NET Core Blazor Applications.
XAF Blazor v24.1 provides a similar experience for both ListView (Column
Chooser) and DetailView (Customization Form). This feature removes the need for
many UI customizations in the design-time Model Editor (inside Visual Studio) -
something many of you love in XAF WinForms UI. Of course, you can also disable
these runtime capabilities for end-users.
BLAZOR – USABILITY
Philippe Petrussa
As mentioned in one of your posts, DevExpress has strongly reduced the
boilerplate code to integrate Blazor editors in XAF Blazor. Great Job!
#TABBED MDI SUPPORT
Tabbed MDI is a multiple document interface (MDI) UI metaphor found in many
modern applications (including your favorite Web browser or Microsoft Outlook
Web). It is a robust interface that maximizes document screen real estate,
especially when working with multiple documents, email messages, etc.
Tabbed MDI is enabled in XAF WinForms apps by default, and XAF Blazor provides a
similar user experience in v24.1. You can also customize Tabbed MDI in the Model
Editor as follows:
* Restore previously opened tabs between application runs
(RestoreTabbedMdiLayout = True by default).
* Refresh View data source on tab focus (RefreshViewOnTabFocus = False by
default)
* Display or hide tab images (ShowTabImage = True by default)
In addition, you can access the underlying tab control in code and configure it
as needed using a Controller (in the "SolutionName.Blazor" project). For
instance, you can load tabs on demand or simultaneously:
* C#
protected override void OnFrameAssigned() {
base.OnFrameAssigned();
Frame.TemplateChanged += Frame_TemplateChanged;
}
void Frame_TemplateChanged(object sender, EventArgs e) {
if(Frame.Template is ITabbedMdiMainFormTemplate template) {
template.TabsModel.RenderMode = DevExpress.Blazor.TabsRenderMode.AllTabs;
}
}
#SIMPLIFIED CREATION OF CUSTOM BLAZOR PROPERTY AND LIST EDITORS
In v24.1, we reduced boilerplate code for many popular UI customization
scenarios:
* Create custom Property and List Editors.
* List/Property Editors access control options in code without adapters.
Previously, XAF Blazor developers had to create intermediate Component Adapter,
Renderer and other boilerplate classes, which were cumbersome or noisy.
With this release, the amount of required code is much less (like its XAF
WinForms counterpart). Our built-in ComponentModel classes now handle component
ValueChanged events (TextChanged, DateChanged, TimeChanged, etc.) and
automatically read and write component values (text, date, time, etc.). The
minimal implementation of a Blazor property editor based on DxTextBoxModel
component model is as follows in v24.1:
* C#
[PropertyEditor(typeof(string), false)]
public class CustomStringPropertyEditor : BlazorPropertyEditorBase {
public CustomStringPropertyEditor(Type objectType, IModelMemberViewItem model) : base(objectType, model) { }
public override DxTextBoxModel ComponentModel => (DxTextBoxModel)base.ComponentModel;
protected override IComponentModel CreateComponentModel() => new DxTextBoxModel();
}
Controller code used to customize a List View or DetailView Property Editor
control is also simpler in v24.1 (since no adapter is required):
* C#
public class CustomizeDateEditorController : ViewController<DetailView> {
protected override void OnActivated() {
base.OnActivated();
View.CustomizeViewItemControl<DateTimePropertyEditor>(this, CustomizeDateTimeEditor);
}
void CustomizeDateTimeEditor(DateTimePropertyEditor propertyEditor) {
// v23.2
//if(propertyEditor.Control is DxDateEditAdapter adapter) {
// adapter.ComponentModel.TimeSectionVisible = true;
//}
// v24.1+
propertyEditor.ComponentModel.TimeSectionVisible = true;
}
}
Our newest Outlook Inspired Demo app contains many custom Property and List
Editors. It’s a great source for UX validation/comparison between v23.2 and
v24.1.

Martin Praxmarer
I really love it – I have integrated the new Blazor Progress Bar in nearly 5
minutes – without creating an adapter – nor an razor component! Thank you Guys –
simply wonderful!
#ACCESSIBILITY ENHANCEMENTS AND KEYBOARD SUPPORT
Currently, XAF (UI for ASP.NET Core Blazor, WinForms, and ASP.NET WebForms)
ships with partial accessibility support mirroring those found in corresponding
DevExpress UI controls across respective UI platforms:
* DevExpress ASP.NET Core Blazor
* DevExpress WinForms
* DevExpress ASP.NET Web Forms
* DevExpress DevExtreme (DevExtreme UI controls are used in XAF ASP.NET Core
Blazor and ASP.NET Web Forms UI.)
XAF Blazor also ships with its own set of UI components/elements (like property
editors and action containers). In v24.1, we extended accessibility support and
improved keyboard support for all XAF Blazor UI elements (~20% of scenarios).
XAF accessibility support will also level up automatically as soon as we enhance
accessibility in DevExpress Blazor UI components throughout 2024.
Our Blazor Grid's keyboard navigation option also officially ships and is
enabled by default in XAF Blazor.
Documentation
BLAZOR – EXTRA MODULES
#SCHEDULER MODULE - SHARED/MULTIPLE RESOURCES
The underlying Blazor scheduler component (DxScheduler) supports multiple
resources for a scheduler appointment/event in v24.1. XAF Blazor Scheduler
module now allows you to use shared resources as well. Previously, only a single
resource was allowed in DxScheduler, and XAF displayed a validation error
message when you attempted to link multiple resources to an appointment.
Documentation
#NOTIFICATIONS MODULE SUPPORT
XAF Blazor v24.1 supports our Notifications Module. The module allows you to
display reminders for scheduler appointments or any custom objects (such as
tasks). The detail form for a scheduler appointment/event also allows you to
configure reminders like those available in Microsoft Outlook.
With the help of the Notifications Module, your app can display a popup window
before appointment/event start times.
Note: our Notifications module does not have to be bound to the Scheduler
module: it can display notifications that originate from anywhere. In the latter
instance, your goal as a developer is to provide the notifications service with
notification items and the service will process them as required.
#MIGRATION TO THE NATIVE BLAZOR REPORT VIEWER
In v24.1, XAF's Blazor Reporting Module uses the native Report Viewer for Blazor
Server apps (DxReportViewer) instead of a JavaScript-based Report Viewer
(DxDocumentViewer).
The native report viewer has a number of benefits for XAF Blazor developers:
* Support of Size Modes and all Blazor themes
* Easier customization without JS using pure C#
* Improved performance: Native implementation reduces load time and increases
page navigation speed when compared to JavaScript wrapper based reporting
tools.

ENTITY FRAMEWORK
#EF CORE 8 ORM SUPPORT
EF Core 8 support officially ships in v24.1 for XAF and associated Backend Web
API Service. EF Core 8 is the latest production-ready version of Entity
Framework.
While EF Core 8 offers numerous advantages over its predecessor (performance and
customization included), it also introduced a series of breaking changes that we
needed to address (for instance, DateOnly and TimeOnly support).
For more information about recent EF Core updates, refer to the following

#CASCADE DELETION FOR AGGREGATED ONE-TO-MANY COLLECTIONS IN EF CORE
With v24.1, XAF's Solution Wizard includes
modelBuilder.SetOneToManyAssociationDeleteBehavior(DeleteBehavior.SetNull,
DeleteBehavior.Cascade); in the OnModelCreating method of EF Core-based apps.
This code will configure "DeleteBehavior.SetNull" for non-aggregated One-to-Many
associations and "DeleteBehavior.Cascade" for aggregated One-to-Many
associations respectively. Previously, XAF's Aggregated attribute was not
considered by EF Core as it was for XPO ORM (and there might be exceptions in
certain ListView scenarios).
Documentation
#NOTEWORTHY EF CORE-RELATED BUG FIXES
In addition to new features, we also addressed the following issues in our v24.1
release cycle:
* T1217729 - Core – Scheduler Event notifications do not work in EF Core
applications
* T1230436 - Core - Properties of base classes not included in EF Core's
DbContext are missing from the Application Model
* T1219872 - Core - Root ListView in the InstantFeedback mode doesn't update
modified object data with EF Core
* T1204704 - WinForms - Column Header Filters are empty for reference
properties with EF Core
SECURITY SYSTEM
#SINGLE SIGN-ON SUPPORT
In v24.1, XAF Blazor and WinForms .NET 6+ apps support Single Sign-On (SSO)
natively. Today, modern business apps are integrated with many external systems
within organizations. For instance, if an organization uses Microsoft 365, XAF
apps are often available at https://myapps.microsoft.com/ among many other apps
within this organization. Since XAF Blazor and WinForms .NET 6+ apps (both XPO
and EF Core-based) support Microsoft Entra ID and other OAuth2 providers,
organizations want/prefer XAF apps to share the same login details or
authentication cookies with existing systems/services such as Microsoft Entra
SSO.
Said differently, organizations require the following: when a user is already
authenticated within the organization (for instance, using Microsoft 365), XAF
apps must seamlessly work with SSO. Previously, XAF developers had to implement
custom solutions to modify XAF’s login form and authentication behavior to
support SSO.
Important SSO scenarios include, but are not limited to the following:
* If a user is NOT logged in within the organization, then XAF apps display a
standard OAuth2/SSO provider logon form (just like Teams, Word or Outlook
normally does for Microsoft 365). If a user was forced to sign out by
administrators, then XAF apps should display the standard logon form as well.
* If a user is logged in within the organization (it can be another non-XAF
app), then no XAF login form is displayed for the user and focus moves
directly to the XAF app UI (by a link from an organization's `Apps dashboard`
or via other methods). The logon procedure in an XAF app proceeds
automatically behind the scenes (via API calls). XAF users should NOT be
forced to explicitly press the “Login with Microsoft” in this instance,
because SSO will "just work" as expected.
Documentation
#BYPASS SECURITY PERMISSION CHECKS FOR INTERNAL BUSINESS LOGIC
In addition, it is now possible to call the new
SetPropertyValueWithSecurityBypass method from within your BaseObject
descendants to bypass security checks for certain protected properties in your
internal application logic (custom base classes are also supported).
This capability is especially valuable to XAF developers when you wish to set
service properties like CreatedBy, ModifiedBy, CreatedOn, UpdatedOn, etc. - our
Audit Trail and Model Difference modules operate using a similar mechanism. The
SetPropertyValueWithBypassSecurity method can freely set protected properties on
behalf of a restricted/regular user in code much like an application
administrator - without having to know admin credentials (like impersonation for
service tasks).
* C#
ApplicationUser GetCurrentUser() {
return ObjectSpace.GetObjectByKey<ApplicationUser>(
ObjectSpace.ServiceProvider.GetRequiredService<ISecurityStrategyBase>().UserId);
}
public override void OnSaving() {
base.OnSaving();
if (ObjectSpace.IsNewObject(this)) {
SetPropertyValueWithSecurityBypass(nameof(CreatedBy), GetCurrentUser());
}
else {
SetPropertyValueWithSecurityBypass(nameof(UpdatedBy), GetCurrentUser());
SetPropertyValueWithSecurityBypass(nameof(UpdatedOn), DateTime.Now);
}
}
As you probably know, this is a long-requested option for many XAFers - an
option that prevented full migration from Integrated Mode to Middle Tier
Security (because CreateNonsecuredObjectSpace and other workarounds were
inconvenient).
The SetPropertyValueWithBypassSecurity also includes certain limitations like
calling this method is only supported from inside BaseObject.OnSaving (for the
best security) or the bypassed property cannot update other protected properties
internally. We are of the opinion that this new option will cover 80% of popular
use-cases.
Breaking Change
#ENHANCED PERFORMANCE FOR MIDDLE TIER SECURITY FOR WINFORMS APPS
XAF WinForms with Middle Tier Security execute much faster in v24.1. We boosted
performance for both EF Core 8 and XPO ORM, as compared to v23.2 (XPO ORM
results are even better - a 2.5x improvement). The graphs below show the current
duration of batch of performance tests and also individual tests in 24.1 vs
v23.2 for EF Core 8.
Breaking Change
MULTI-TENANCY
#EXTEND THE BUILT-IN TENANT CLASS WITH CUSTOM FIELDS
You can now extend the standard Tenant class to associate additional data (for
instance, module and feature license info) with tenants stored in the
application’s Host Database. Of course, you can also access custom Tenant fields
in code later (from a Controller or Application Builders). We also supported
this for both EF Core and XPO ORM.
* C#
// MySolution.Module\BusinessObjects\CustomTenant.cs
// EF Core
using DevExpress.Persistent.BaseImpl.EF.MultiTenancy;
public class CustomTenant : Tenant {
public virtual string CustomField { get; set; }
}
// MySolution.Blazor.Server/Startup.cs (MySolution.Win/Startup.cs)
builder.AddMultiTenancy()
.WithCustomTenantType<CustomTenant>()
//...
#MIDDLE TIER SECURITY FOR WINFORMS APPS: MULTI-TENANCY AND OAUTH2 SUPPORT
In v24.1, XAF WinForms apps (.NET 6+) with Middle Tier Security natively
supports Multi-Tenancy and OAuth2 providers (for example, Microsoft Entra ID or
Google). Our Outlook Inspired Demo now also uses Middle Tier Security with the
Multi-Tenancy module.
As we described in our Security Considerations help topic, Windows desktop apps
can better meet enterprise security standards with our Middle Tier application
server. With our solution, EF Core or XPO developers can retain their standard
DbContext or Session and initiate remote connections to a data store from any
.NET client (like XAF WinForms or non-XAF apps). This capability is critical
within certain environments/business apps (those that cannot maintain direct
database connections because of security considerations).
Non-XAF EF Core or XPO developers can benefit from our Middle Tier application
server and preserve DbContext or Session with their entity data model (learn
more). This is especially critical for many desktop .NET developers (WinForms,
WPF, WinUI, etc.), who are now required to meet higher security standards. In a
nutshell, these developers need to either retrofit/modernize their "fat clients"
for Windows (#1) or redo everything from scratch using modern Web technologies
and Cloud services (#2). Our Middle Tier Security allows you to choose the
"easier" and potentially more reliable route (#1), and to "replace" direct
database connections with middleware. Review the following code snippet for more
information in this regard:
* C#
var httpRemoteRepository = new HttpRemoteRepository(httpClient, typeof(EFCoreDbContext).FullName);
var optionsBuilder = new DbContextOptionsBuilder<EFCoreDbContext>();
optionsBuilder.UseMiddleTier(opt =>
opt.UseRemoteRepository(httpRemoteRepository));
optionsBuilder.UseChangeTrackingProxies();
optionsBuilder.UseLazyLoadingProxies();
var dbContextOptions = optionsBuilder.Options;
var dbContext = new EFCoreDbContext(dbContextOptions);
var users = dbContext.Employees.ToList();
#WEB API SERVICE FOR XAF & NON-XAF UI CLIENTS (POWERED BY EF CORE & XPO ORM)
In v24.1, our Backend Web API Service supports Multi-Tenancy for both EF Core
and XPO ORM.
Our Web API Service has both FREE (basic CRUD) and paid features (such as
reporting, audit trail, validation, file attachments, localization, etc). We
also distribute many demo applications illustrating the use of free and paid
APIs with .NET MAUI, Blazor WebAssembly, JavaScript and even more (for paid
features, you must own a DevExpress Universal Subscription license).
To learn more about our Web API Service and determine whether it can be of value
within your organization, please review the following blog post: Common
Questions about the New DevExpress Web API Service (powered by Entity Framework
and XPO ORM).
CROSS-PLATFORM ENHANCEMENTS
#MIGRATION FROM NEWTONSOFT.JSON TO SYSTEM.TEXT.JSON
"System.Text.Json" library is now used to deserialize input parameters for
Backend Web API Service endpoints.
For more information, refer to the following blog post: .NET and .NET Framework
— Migration from Newtonsoft.Json to System.Text.Json (v24.1).
Breaking Change
#SUPPORT OF NEW .NET DATEONLY AND TIMEONLY TYPES FOR EF CORE 8 AND
BLAZOR/WINFORMS UI
As you probably read in the EF Core 8 breaking changes above, SQL Server date
and time now scaffold to .NET DateOnly and TimeOnly, Grid List Editor and
associated Date/Time Property Editors in XAF Blazor and WinForms apps for .NET
6+ now support the new .NET types accordingly.
The underlying Blazor and WinForms grid components support operations with
DateOnly/TimeOnly (sorting, grouping, filtering, including Filter Editors auto
filter rows, column header filters) - as will Criteria Language, Server Mode,
and other underlying data access components for EF Core.
#COMMAND LINE INTERFACE (CLI) SOLUTION WIZARD TEMPLATES
XAF v24.1 allows you to use the .NET command line interface (CLI) or the
`dotnet` tool to quickly create XAF Blazor and WinForms apps from the console
(without using XAF's Solution Wizard). This is similar to the DevExpress Reports
implementation: Use .NET CLI Templates.
This capability is valuable for XAF developers using Microsoft Visual Studio
Code (VS Code) or JetBrains Rider in both Windows and non-Windows development
environments (like Linux or MacOS). Previously, these users had to first create
XAF projects in Visual Studio for Windows using the Solution Wizard.
* CLI
dotnet new install DevExpress.XAF.ProjectTemplates::24.1.3
dotnet new dx.xaf -p blazor win -e2e -api Standalone -s MiddleTier -n MyCoolApp
cd MyCoolApp
dotnet run

#XPO ORM DATA MODEL WIZARD — TRUST LEVEL CERTIFICATE AND ENCRYPTION OPTIONS
Please note that the changes described below are already available in the latest
update of our current major version: v23.2.5.
We enhanced the user experience in our Data Source Wizard while binding a report
to an instance of the MS SQL Server. The data source connection screen now
features two new options marked on the screenshot:
These new options/changes allow you to avoid the "The certificate chain was
issued by an authority that is not trusted" error while binding a report to MS
SQL Server database if you cannot set up MS SQL Server differently. Learn more
about this error and its cause in the following Microsoft topic: The certificate
chain was issued by an authority that isn't trusted - SQL Server (Microsoft

CODERUSH FOR VISUAL STUDIO V24.1
VOICE SUPPORT
After you specify Azure Speech Recognition and OpenAI API keys in Voice Setup,
you can enable voice features in Visual Studio 2022 and up.
Voice setup instructions
#VOICE COMMANDS
Hold left Ctrl key and speak to trigger voice commands. Examples of things you
can say and what they do:
* "open foo" - finds and opens Foo.cs file in editor
* "class bar" - navigates to classes named "bar"
* "bookmark storage" - creates a new bookmark named "storage"
* "goto storage" - jumps to a bookmark named "storage"
* "show me solution explorer" - shows the Solution Explorer
* "line one hundred" - jumps to line 100 in current file
Voice commands can use inferred intent, so you don't have to be precise when
invoking them. Also, if you're working in large solutions (e.g., with 10,000+
files) the Voice Command for opening files is a huge productivity boost.
#VOICE TO CODE
Hold right Ctrl and speak to dictate strings, comments, and expressions, and to
name identifiers. Examples of what you can create with voice:
* A new PascalCase or camelCase identifier name when Visual Studio's Rename
refactoring is active.
* Dictated strings (including expressions in interpolated strings).
* Dictated comments (including indentifier references in comments and paramref
and seealso tags in XML Doc comments)
Expressions and statements:
* Simple expressions, like method and property calls, numbers and binary
expressions.
* More advanced expressions, like await expressions, null, true and false
literals, discards, method calls with out and ref arguments, and assignment
statements.
#VOICE FOR COPILOT
Hold left Ctrl and speak "Hey Copilot!" followed by your query to interact with
the GitHub Copilot Chat tool window using your voice. You can use words like
"this method" or "this class" to automatically include relevant code in your
query. If the Copilot tool window is already active and its chat prompt has
focus, you can hold the right Ctrl key down to directly dictate your query into
the prompt control (there's no need to start your prompt with "Hey Copilot").
NAVIGATION
New quick navigation providers:
* MEF Imports - find where the active type is imported.
* MEF Exports - find where the active type is exported.
* Type - go directly to the type of active variable or property.

Please, review the description of VCL-related features below and leave your
feedback at the end of the section.
Go to the survey now.
RAD STUDIO 12.1 SUPPORT
DevExpress VCL v24.1 and v23.2.6+ officially support Delphi 12.1 and C++ Builder
12.1 (for both 32-bit and 64-bit). If you installed RAD Studio 12.1 previously,
please apply its Patch 1, because it addresses the RSS-536 incompatibility issue
for the Delphi 64-bit compiler (Blog Post). Also, beware a known performance
issue in our Rich Text Editor due to the System.Generics.Defaults unit changes.
HIGH DPI SUPPORT
#ENHANCED HIGH DPI RESOLUTION AND VECTOR SKIN/IMAGE SUPPORT
In addition to new features, we also focus on bug fixes, especially for High
DPI-related issues, vector skins, and performance bottlenecks. Ultimately, we
want our VCL UI components to be polished, modern, and stand out among all
competitors in these aspects (UI matters and this affects almost every VCL
customer).
Many "fixes" are technically "features". We've recently started to publish more
bug reports (for instance, from our internal/private testing) and also include
more information into all bug reports such as screenshots before/after and
samples - everybody can review this info and analyze the complexity of the work
involved.
#NEW VECTOR THEME - WINDOWS 11 (WXI) COMPACT
We now ship our WXI Compact Skin - a clone of the WXI skin with smaller paddings
and margins, which many of you were used to from traditional DevExpress VCL
skins such as Bezier, Office, etc.
To enable the new WXI Compact Skin, assign WXICompact to the TdxSkinController
component's SkinName property.
#EASIER SVG ASSIGNMENT FOR IMAGE LISTS AT DESIGN-TIME
In v24.1, the DevExpress VCL Ribbon (and other UI controls) allow you to use a
single image list for large and small SVG icons. With this capability you can
simply specify a small SVG icon and we will scale it up automatically (for
instance, in places where the control needs a large icon in the Ribbon). This
will improve overall usability and should reduce time spent/maintenance in half.
Based on our roadmap survey votes, we made it possible for customers to use both
old and new icon assignment strategies using UseRegularAsLarge, LargeSize and
related SVG image options. Existing apps and usage habits will remain
unaffected.
#LAYOUT AND IMAGE MODIFICATIONS IN DESIGN-TIME WIZARDS AND DIALOGS
VCL v24.1 includes dozens of layout and `raster to vector` image adjustments in
key design-time areas (wizards, designers, and dialogs). High DPI support is
crucial and we want to set the highest standards in this regard (in terms of
developer usability and speed).
DATA-AWARE CONTROLS AND MENU
#ACCESSIBILITY ENHANCEMENTS AND KEYBOARD SUPPORT
Previous versions of the DevExpress ExpressBars and ExpressNavBar Suite included
partial accessibility support (powered by Microsoft Active Accessibility or
MSAA). We initially hoped to use MSAA to support remaining VCL controls, but
research showed that it is not technically feasible. It turned out that this
COM-based technology is outdated for modern accessibility requirements and
highly interactive UI controls like ours.
Accordingly, we built a new engine for ongoing accessibility-related
enhancements (it is powered by Microsoft UI Automation or UIA - used in
DevExpress WinForms and WPF products). UIA gave us much more flexibility and
allowed to introduce the following accessibility-related v24.1 features:
* UIA-powered controls now include Automation options like Name, Description,
etc.
* UIA-powered controls now include specialized events to customize Automation
options at runtime.
* UIA-powered controls currently include Button, Check Box, Radio Button, Group
Box, Panel, Text Editor, Button Editor, and Label.
Our effort in this regard work will continue throughout 2024-2025, and will
include enhancements for key unsupported components:
* Data grid (key navigation and "read-only" scenarios, likely without data
editing and other complex interactions in the first release)
* Form layout manager (including layout groups, tabs, etc.)
* Navigation and menu (key scenarios in both Ribbon and standard toolbars)
* TreeList, Scheduler, Pivot Grid, and other popular data editors (key
scenarios in both in-place and standalone editors)
#ACCENT-INSENSITIVE OPERATION SUPPORT FOR DATA-AWARE CONTROLS
With v24.1, you can configure how various diacritic glyphs in letters (umlauts,
grave, acute, and other accents) are treated. For instance, if you type "Joao"
in a search box, Data Grid filtering results will include data records with both
"João" and "Joao". For more information, read the following quote from
Wikipedia:
A diacritic (also diacritical mark, diacritical point, diacritical sign, or
accent) is a glyph added to a letter or to a basic glyph. The term derives from
the Ancient Greek διακριτικός (diakritikós, "distinguishing"), from διακρίνω
(diakrī́nō, "to distinguish"). The word diacritic is a noun, though it is
sometimes used in an attributive sense, whereas diacritical is only an
adjective. Some diacritics, such as the acute ⟨á⟩, grave ⟨à⟩, and circumflex ⟨â⟩
(all shown above an 'a'), are often called accents. Diacritics may appear above
or below a letter or in some other position such as within the letter or between
two letters.
You can enable or configure accent-insensitive operations globally using the
TdxDiacriticStringOptions class:
* ComparisonMode: allows you to switch between comparison modes (Auto,
Sensitive, Insensitive). By default (Sensitive), we do not ignore accents.
Insensitive mode can be of value for global organizations with users from
different countries/data (for instance, names of employees or goods can be in
different languages).
* NormalizationMode: specifies the string normalization algorithm (Fast,
System) used for string comparison in diacritic-insensitive mode. The default
algorithm (Fast) works up to 3 times faster compared to the operating
system-dependent algorithm (System).
Note: TdxDiacriticStringOptions does not work in Server Mode – use database
collation options instead.
Impacted text-comparison operations and control features include:
* Sorting
* Grouping
* Incremental search
* Auto-filter row
* Find panel, etc.
This behavior expands to the following controls:
* Navigation control
* Ribbon and standard toolbars
* Lookup editors
* Data grid
* Pivot grid
* Tree list
* Other data-bound controls (powered by our Data Controller).
#EDITING OPERATIONS (ROTATE, CROP, FLIP, ETC.) IN IMAGE CONTROLS
You can now invoke the Image Editor dialog for TcxImage and TcxDBImage
components using the Edit context menu command. Our design-time Image Picker
dialog includes the new Edit command as well. The Edit command unlocks basic
image editing operations:
* Crop and straighten
* Adjust brightness, contrast and saturation
* Mirror
* Rotate, etc.
The Image Editor maintains operation history and offers both undo and redo
functionality. Once the editor is closed and changes are saved, modifications
cannot be undone.
VCL IMAGEEDIT WITH INTEGRATED IMAGE EDITOR
slide 3 of 2
#EXIF METADATA SUPPORT IN IMAGE CONTROLS
In v24.1, our image controls (TcxImage and TcxDbImage) read and interpret EXIF
metadata from images and modify the image display accordingly. For instance, our
image controls automatically rotate the image based on orientation metadata
(unlike the standard TImage control and certain image viewers).
Impacted image-based scenarios (where rotation will take place) include:
* Data Grid cells
* TreeList cells
* Vertical and Property Grid cells
Previously, this required a complex custom solution with a manual call of the
Rotate method. Customers who implemented custom solutions on their own (for
instance, image rotation in the grid or standalone image editors), can disable
this default behavior using a static feature toggle. The
TdxGPImage.DefaultImageExifAutoRotation class property value defines if the
image editor rotates an image based on EXIF metadata.
#FIELD NAME-BASED EXPRESSIONS FOR DATA-AWARE CONTROLS
With v24.1, you can use {FieldName} in formula expressions in conditional
formatting rules to refer to a field by underlying name instead of a display
name. Previously, you could only use a display name/caption or an index. This
capability will help you create formulas for conditional formatting rules.
This is helpful in VCL apps that support multiple languages or other scenarios
where you cannot rely on a field caption (due to its dynamic nature such as
translation to another language).
Review expression syntax examples for conditional formatting expressions in our
Online Documentation.
RIBBON CONTROL
#OFFICE 365 STYLE FOR VCL RIBBON CONTROL
Our VCL Ribbon Control ships with a new Office 365 rendering style. When our new
Office 365 style is used, the Ribbon control displays a Search box at the top of
the Ribbon form and Show Ribbon options on the bottom right of the Ribbon UI.
CHART CONTROL
#SECONDARY AXES
Secondary axes can be of value if you need to display multiple scales with
different measurement units. You can now use SecondaryAxes.AxesX and
SecondaryAxes.AxesY properties to add and configure supplemental axes for the
main axis of arguments (X-axis) and main axis of values (Y-axis).
The following code snippet creates a secondary axis of values and associates it
with the first series in an XY diagram. Refer to the TdxChartSecondaryAxes class
description for detailed information on available options.
* Delphi
var
ADiagram: TdxChartXYDiagram;
AAxisY: TdxChartSecondaryAxisYCollectionItem;
AXYSeries: TdxChartXYSeries;
begin
if dxChartControl1.DiagramCount = 0 then Exit;
ADiagram := dxChartControl1.Diagrams[0] as TdxChartXYDiagram;
if ADiagram.SeriesCount = 0 then Exit;
ASeries := ADiagram.Series[0];
AAxisY := ADiagram.SecondaryAxes.AxesY.Add;
ASeries.View.AxisY := AAxisY.Axis;
AAxisY.Title.Text := 'Income (USD)';
AAxisY.Title.Alignment := TdxAlignment.Center;
AAxisY.Appearance.Color := TdxAlphaColors.Gray;
end;
#LOGARITHMIC SCALES
A logarithmic scale can be of value when you need to display a value range that
differs by large orders of magnitude. You can now set the Logarithmic property
to True or False to switch between logarithmic and standard numeric scales for
the axis (TdxChartCustomAxis). The LogarithmicBase property helps you specify
the base of the logarithm (for the logarithmic scale of the axis - default is
10).
#POINT AND SEGMENT COLOR CUSTOMIZATION VIA EVENTS
You can handle OnGetSeriesPointDrawParameters and OnGetValueLabelDrawParameters
events to customize individual series points and associated value labels based
on specific conditions.
Example #1: Generate unique fill colors for all point markers in the series
(Europe's population).
* Delphi
procedure TFeaturesDemoMainForm.cdLineGetSeriesPointDrawParameters(
Sender: TdxChartCustomDiagram;
AArgs: TdxChartGetSeriesPointDrawParametersEventArgs);
var
ALineDrawParameters: TdxChartLineSeriesPointDrawParameters;
APalette: TdxChartPalette;
APaletteItem: TdxChartPaletteItem;
begin
APalette := TdxChartStandardPaletteRepository.FindPalette('Slipstream');
if AArgs.SeriesPoint.Series.Caption = 'Europe' then
begin
if AArgs.DrawParameters.ClassType <> TdxChartLineSeriesPointDrawParameters then Exit;
ALineDrawParameters := AArgs.DrawParameters as TdxChartLineSeriesPointDrawParameters;
APaletteItem := APalette.GetColorsForIndex(AArgs.SeriesPoint.Index);
ALineDrawParameters.MarkerAppearance.FillOptions.Color := APaletteItem.Color;
end;
end;
Example #2: Display different measurement units for value labels (millions or
thousands of $).
* Delphi
procedure TMyForm.cdAreaGetValueLabelDrawParameters(Sender: TdxChartCustomDiagram;
AArgs: TdxChartGetValueLabelDrawParametersEventArgs);
begin
if AArgs.SeriesPoint.Value >= 1000 * 1000 then // Millions
AArgs.Text := Format('%.1fM', [AArgs.SeriesPoint.Value / (1000 * 1000)])
else if AArgs.SeriesPoint.Value >= 1000 then // Thousands
AArgs.Text := Format('%.0fk', [AArgs.SeriesPoint.Value / 1000])
else
AArgs.Text := Format('%0f', [AArgs.SeriesPoint.Value]);
end;
Review more code examples for Area, Line, Bar, Pie chart views in our Online
Documentation.
#PALETTES
You can now use the Palette property to switch between color palettes whose
color sets are applied to individual simple series values and XY series. The
following code snippet applies a predefined palette ("Nature Colors") to the
chart control:
* Delphi
dxChartControl1.Palette := TdxChartStandardPaletteRepository.FindPalette('Nature Colors');
You can also add a TdxChartPaletteRepository component to create and manage
custom palettes. The following code snippet creates a user palette with three
colors and applies the palette to the chart control:
* Delphi
var
AChartPalette: TdxChartUserPalette;
begin
AChartPalette := dxChartPaletteRepository1.CreateItem;
AChartPalette.Name := 'My Palette 1'; // Assigns a unique palette name
AChartPalette.Count := 3; // Sets the size of the palette item array
AChartPalette.Items[0] := TdxChartPaletteItem.Create(TdxAlphaColors.Red);
AChartPalette.Items[1] := TdxChartPaletteItem.Create(TdxAlphaColors.Green);
AChartPalette.Items[2] := TdxChartPaletteItem.Create(TdxAlphaColors.Blue);
dxChartControl1.Palette := AChartPalette;
end;
You can also switch between color palettes at runtime, if necessary.
You can find more information on predefined and custom palettes in our Online
Documentation
