What's New
Data Grid - Virtual Scrolling
The DevExpress Blazor Data Grid now supports virtual scrolling – allowing your end-users to navigate individual grid rows via the control’s vertical scrollbar.
Use the DataNavigationMode property to enable virtual scrolling:
<DxDataGrid Data=@DataSource ... DataNavigationMode="@DataGridNavigationMode.VirtualScrolling" ... </DxDataGrid>
ComboBox - Virtual Scrolling
The DevExpress Blazor ComboBox can now load visible items within its drop down list (loads data virtually and on demand). This improves performance when binding to a large dataset.
Set the DataLoadMode property to enable virtual scrolling:
<DxComboBox Data=@Strings DataLoadMode="@ComboBoxDataLoadMode.VirtualScrolling" FilteringMode="@FilteringMode.Contains" @bind-SelectedItem=@SelectedItem> </DxComboBox>
