DataGrid

Blazor

Bug Fixes

#I847158, FB74505 - Resolved an issue where DataGrid data was hidden after using ResetPersistDataAsync in other tabs.
#I847012, FB74462 - Resolved an issue where Filtering did not work correctly for blank values in the DataGrid.
#I846846, FB74485 - Resolved a Filtering issue when using delay in the Custom Adaptor Read method in the DataGrid.

Features

#I780368, FB35651, FB70961 - The Blazor DataGrid now supports explicit selection of filter operators through an inline dropdown available in each FilterBar cell. It also introduces type‑specific UI components—such as DatePicker, NumericTextBox, and DropDownList—for entering filter values. Explore the demo here

Code Example:

<SfGrid TValue="Order" DataSource="@Orders"  AllowPaging="true" AllowFiltering="true">
<GridFilterSettings ShowFilterBarOperator="true" Type="FilterType.FilterBar" ></GridFilterSettings>
<GridColumns>
<GridColumn Field="@nameof(Order.OrderID)" HeaderText="Order ID" Width="120" />
<GridColumn Field="@nameof(Order.CustomerID)" HeaderText="Customer ID" Width="150" />
<GridColumn Field="@nameof(Order.Freight)" HeaderText="Freight" Format="C2" Width="120" />
</GridColumns>
</SfGrid>

FB16336 - The Blazor DataGrid now supports single‑click cell editing in Batch Editing mode through the AllowEditOnSingleClick API. This enhancement reuses the existing editing, saving, validation, and event workflows.

Code Example:

<SfGrid TValue="Order" DataSource="@Orders"  AllowPaging="true" Toolbar="@(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" })">
<GridEditSettings AllowAdding="true" AllowEditing="true" AllowDeleting="true" Mode="EditMode.Batch" AllowEditOnSingleClick="true"></GridEditSettings>
<GridColumns>
<GridColumn Field="@nameof(Order.OrderID)" HeaderText="Order ID" Width="120" />
<GridColumn Field="@nameof(Order.CustomerID)" HeaderText="Customer ID" Width="150" />
<GridColumn Field="@nameof(Order.Freight)" HeaderText="Freight" Format="C2" Width="120" />
</GridColumns>
</SfGrid>

I834437, FB73893 - The Blazor DataGrid now supports proper character encoding during CSV export, preventing special characters from appearing incorrectly. This enhancement is enabled through the newly introduced Encoding property in ExcelExportProperties, ensuring consistent and accurate rendering of exported data across different tools and formats.

Code Example:

<SfGrid TValue="Order" @ref="Grid" DataSource="@Orders" Toolbar="@(new List<string>() { "CsvExport"})" AllowExcelExport="true">
<GridEvents OnToolbarClick="ToolbarClick" TValue="Order"></GridEvents>
<GridColumns>
<GridColumn Field="@nameof(Order.OrderID)" HeaderText="Order ID" Width="120" />
<GridColumn Field="@nameof(Order.CustomerID)" HeaderText="Customer ID" Width="150" />
<GridColumn Field="@nameof(Order.Freight)" HeaderText="Freight" Format="C2" Width="120" />
</GridColumns>
</SfGrid>
@code{
SfGrid<Order>? Grid;
List<Order> Orders { get; set; }
public void ToolbarClick(Syncfusion.Blazor.Navigations.ClickEventArgs args)
{
this.Grid.ExportToCsvAsync(new ExcelExportProperties
{
Encoding = System.Text.Encoding.UTF8,
});
}
}

Breaking Changes

The Blazor DataGrid now delivers improved consistency when applying filter operators such as Does Not Start With and Does Not End With during popup data requests.

Previously, the filtering behavior in these scenarios followed a different interpretation of the operator logic. With this update, the behavior has been aligned to match the standard expected outcomes, ensuring that both Menu and Excel filters produce consistent and accurate suggestions during value entry and final filtering.

Angular

Bug Fixes

#I844794 - Resolved an issue where the “Select All” action failed to work when using remote data without paging or virtual scrolling.

Features

Introduced DOM virtualization support to improve rendering performance by minimizing the number of DOM elements created during scrolling, making the Grid more efficient when handling large datasets.
Added support for cell level editing, allowing users to edit individual cells directly without switching an entire row into edit mode, thereby improving editing flexibility and overall user experience.
Implemented undo and redo functionality for batch editing in the Grid, enabling users to easily revert or reapply changes and enhancing overall data manipulation usability.
Enabled immediate filtering support in Excel and Checkbox filter types, allowing filter operations to be applied instantly without requiring users to explicitly confirm their selection.
Enhanced the Column Chooser with immediate show and hide action support, so column visibility changes are reflected instantly when toggled, improving usability and interaction speed.
Added support for setting the Grid height using viewport height units, enabling better responsiveness and adaptability across different screen sizes.
Introduced support for displaying footer aggregate values while using column virtualization, ensuring accurate summary information even in highly optimized rendering scenarios.
Added a new cellFocus event that is triggered whenever a grid cell receives focus, providing better control for developers to handle focus-related interactions and improve accessibility.
Introduced detailExpanded and detailCollapsed events to notify when detail rows are expanded or collapsed, allowing developers to track and respond to detail row state changes effectively.

SmartDataGrid

.NET MAUI

Breaking Changes

The NuGet package and namespace for the SfSmartDataGrid control have been updated in this release.

Description

Previously, the SfSmartDataGrid control was included in the shared Syncfusion.Maui.SmartComponents NuGet package and namespace. To enhance modularity and improve maintainability, it has now been separated into its own dedicated NuGet package and namespace.

NuGet Change

Old NuGet package: Syncfusion.Maui.SmartComponents
New NuGet package: Syncfusion.Maui.SmartDataGrid

Namespace Change

Old namespace: Syncfusion.Maui.SmartComponents
New namespace: Syncfusion.Maui.SmartDataGrid

Impact

Applications that use the SfSmartDataGrid control and reference the old NuGet package or namespace will encounter compilation errors after upgrading to this version.

Action Required

Replace the old NuGet package with the new Syncfusion.Maui.SmartDataGrid package.
Update all namespace references in both C# and XAML code to the new namespace.
