My requirement is to place a set of RadGridView horizontally, there's a ScrollViewer and ItemsControl, see code below.

 <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Disabled">
	<Grid>
		<ItemsControl Name="GridItemsControl" HorizontalAlignment="Left" HorizontalContentAlignment="Left"
					  ItemsSource="{Binding Results}">
			<ItemsControl.ItemsPanel>
				<ItemsPanelTemplate x:Uid="ItemsPanelTemplate_1" x:Name="GridItemPanelTemplate">
					<DockPanel x:Uid="DockPanel_1" />
				</ItemsPanelTemplate>
			</ItemsControl.ItemsPanel>
			<ItemsControl.ItemTemplate>
				<DataTemplate x:Uid="DataTemplate_5">
					<telerik:RadGridView Grid.Row="0"
									 Margin="8"
							 ItemsSource="{Binding Items}" 
							 AutoGenerateColumns="False" 
							 IsReadOnly="True"
							 GroupRenderMode="Flat"
							 ShowGroupPanel="False"
							 CanUserSortColumns="False" 
							 ShowColumnSortIndexes="False"
							 RowIndicatorVisibility="Collapsed" 
							 CanUserGroupColumns="False"
							 SelectionMode="Extended"
							 ClipboardCopyMode="All" >
						<telerik:RadGridView.Columns>
							<telerik:GridViewDataColumn Width="Auto"
														Header="Depth"
												IsFilterable="False"
												ShowToolTipOnTrimmedText="True" 
												TextAlignment="Right"
												DataMemberBinding="{Binding Depth}">
							   
							</telerik:GridViewDataColumn>
						</telerik:RadGridView.Columns>
					</telerik:RadGridView>
				</DataTemplate>
			</ItemsControl.ItemTemplate>
		</ItemsControl>
	</Grid>
</ScrollViewer>

The UI got stuck while the program was running, but when replace RadGridView by DataGrid, it can run, and if I replace the Grid with ListView, the UI can work, but the function not meet my requirement
