Currently, when dragging a column's header outside of RadGridView, no icon is shown to indicate that it cannot be dropped there. Whereas dragging an item outside of the bounds of a RadListBox, a cannot drop icon is shown. We could update the drag-drop logic of the column's header to include a similar behavior.

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.

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.

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:

The rows are measured and arranged wrongly when the ItemsSource is assigned to VirtualQueryableCollectionView. To reproduce this, one of the rows should measure with different height than the others. Also, this is reproducible only when the GroupRenderMode is set to Flat.

To work this around, set the GroupRenderMode property of RadGridView to Nested or avoid using VirtualQueryableCollectionView.

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.

Column groups may disappear when the RadGridView control is hosted in a TabItem of TabControl. These column groups can disappear when new GridViewColumnGroup instances are created.

Furthermore, resizing a column of RadGridView will result in a NullReferenceException.

To work this around, set the EnableColumnGroupsVirtualization property of RadGridView to False.

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 horizontal scrollbar of the GridViewScrollViewer automaticall scrolls slightly to the left when the layout is updated and the HorizontalOffset was at the end of the GridView before the update. A layout update in this context can be resize of the RadGridView control or a vertical scroll action in a child RadGridView element.
