The column group headers are not displayed when the DisplayIndex property of the GridViewColumn objects is set before the control is loaded.

To work this around, you can set the DisplayIndex of the columns after the RadGridView is loaded.

Empty cells appear when the RadGridView contains many cells in the viewport and the view gets resized.

To work this around you can extract and modify the ControlTemplate of GridViewCell, in order to set the MinHeight property of the "PART_ContentPresenter" element to a number close to the RowHeight of the RadGridView control.

The cell content gets clipped when the width of the previous column changes at runtime. This happens in the Windows11 and Office2019 themes (possibly in others) and only if the clipped cell is position before the right frozen columns area.

To work this around, you can call the Rebind() method of RadGridView, after the column width changes.

The vertical scrolling seems to become very slow and even unresponsive, when the following conditions are met:

• left and right frozen columns count is 0
• the summary width of all columns is smaller than the width of the RadGridView element

To minimize the issue, you can set the GroupRenderMode property of RadGridView to Nested.

Currently, if RadGridView is bound to a INotifyCollectionChanged collection and the collection class raises the CollectionChanged event with NotifyCollectionChangedAction set to Add, Remove or Insert, RadGridView is not updating its items properly when the OldItems or NewItems collections contain more than 1 items.

Add support for this scenario.

Hello,

Regarding this forum question, it will be good if you add the attached property VisibleColumnsCount or IsAnyColumnVisible so I can hide the rows when there are 0 columns. Please read the following link for full information:

Currently, the GridViewMergedCell cannot be selected. Allow selecting the merged cells via the UI or code. 

At the moment RadGridView has only a CurrentMergedCell property.

In the following scenario:

<telerik:RadGridView x:Name="clubsGrid" ItemsSource="{Binding Foos}" AutoGenerateColumns="False">
	<telerik:RadGridView.Columns>
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo1}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo2}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo3}" Width="*" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo4}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo5}" MinWidth="100" />
		<telerik:GridViewDataColumn DataMemberBinding="{Binding Foo6}" MinWidth="100" />
	</telerik:RadGridView.Columns>
</telerik:RadGridView>

<DataGrid ItemsSource="{Binding Foos}" AutoGenerateColumns="False" Grid.Row="1">
	<DataGrid.Columns>
		<DataGridTextColumn Binding="{Binding Foo1}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo2}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo3}" Width="*" />
		<DataGridTextColumn Binding="{Binding Foo4}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo5}" MinWidth="100" />
		<DataGridTextColumn Binding="{Binding Foo6}" MinWidth="100" />
	</DataGrid.Columns>
</DataGrid>

in the native DataGrid after the Width of Foo4 column is increased towards Foo3, then the Width of Foo5/Foo6 columns can also be increased. We can implement similar behavior in the RadGridView as well.
