The class Telerik.Windows.Data.QueryableExtensions has a static dictionary "providerIsEntityFrameworkCore"

That dictionary will hold a reference (forever) to a collection that is set as Source for the GridView.

Reason is that non IQueryable-types will be wrapped in a EnumerableQuery<T> that will return itself as the provider (https://referencesource.microsoft.com/#System.Core/System/Linq/SequenceQuery.cs,44), encapsulating the reference.

This must be something introduced recently.

Currently, when setting ShowToolTipOnTrimmedText, the duration of the displayed tooltip is hardcoded to 5 seconds. Add an API to change the duration.

Especiall for wide lists it would be very helpful to be able to zoom in and out of a RadGridView, in order to see more or less columns.

You are able to resize columns using the columns gripper. The corresponding group will be automatically resized. We can provide a way to resize the column groups. The columns inside the group will be automatically resized with the group.

Release R1 2021 SP1

In this particular case, the DisplayIndex properties of the parent and child grid are bound to property from our ViewModel. When the parent grid columns are reordered runtime, the columns of the child grid are also reordered. But when sorting is performed by clicking on a column header, an exception is thrown.

The RadGridView's is bound to an empty DataView and grouped by a GridViewComboBoxColumn. When adding items during runtime, setting the SelectedItem in code or selecting through the UI -> the SelectedItem remains null.

This behavior is reproducible when the VisualStudio2013 theme is applied. The control is not resized correctly when the ItemsSouce is changed with a different number of columns.

Release LIB 2021.1.201

Changing the TextAlignment property of the GridViewExpressionColumn doesn't refresh the cells, thus the change is not visible in the UI.

To work this around, remove and add again the corresponding column in the Columns collection of RadGridView. Or define a CellTemplate and use a TextBlock control with its TextAlignment bound to the column's property.

<telerik:GridViewExpressionColumn.CellTemplate>
	<DataTemplate>
		<TextBlock Text="{Binding}" 
				   TextAlignment="{Binding RelativeSource={RelativeSource AncestorType=telerik:GridViewCell}, Path=Column.TextAlignment}"  />
	</DataTemplate>
</telerik:GridViewExpressionColumn.CellTemplate>

Memory leak appears when exporting to Xlsx and Pdf formats.

To work this around, you can call one of the export methods GridViewDataControlExportExtensions with empty arguments.

Workbook workbook = this.gridView.ExportToWorkbook();
try
{
	GridViewDataControlExportExtensions.ExportToWorkbook(new RadGridView(), new GridViewDocumentExportOptions());
	GridViewDataControlExportExtensions.ExportToWorkbook(null);
}
catch (ArgumentException)
{
}

In this scenario, we have two grids in different windows on different threads. When reordering columns in the first grid and reordered rows in the second will lead to an exception: System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

The GridViewSelectColumn is a very nice and useful feature, especially the possibility to select all items with just one click on the header. It would be great if there was the same functionality for the group header. So clicking on a checkbox in group header will select all items in this group (only). I know there are some examples (many years old) of how to do this, but it would be much better if it worked out-of-the-box.
