Enable the Horizontal and Vertical Scrollbars
Updated on Sep 23, 2026
For example, you may have the following treeview:
XAML
<telerik:RadTreeView x:Name="radTreeView">
<telerik:RadTreeViewItem Header="Sport Categories">
<telerik:RadTreeViewItem Header="Football">
<telerik:RadTreeViewItem Header="Futsal"/>
<telerik:RadTreeViewItem Header="Soccer"/>
</telerik:RadTreeViewItem>
<telerik:RadTreeViewItem Header="Tennis"/>
<telerik:RadTreeViewItem Header="Cycling"/>
</telerik:RadTreeViewItem>
</telerik:RadTreeView>
In order to enable horizontal and/or vertical scrollbar you need to add the following attribute(s) to the RadTreeView declaration:
XAML
<telerik:RadTreeView x:Name="radTreeView2" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Visible">
</telerik:RadTreeView>And here is the result:
The same operation can be done in the code-behind:
C#
private void EnableScrollBars()
{
ScrollViewer.SetHorizontalScrollBarVisibility(radTreeView, ScrollBarVisibility.Visible);
ScrollViewer.SetVerticalScrollBarVisibility(radTreeView, ScrollBarVisibility.Visible);
}If you want to enable the scrollbars on demand, you need to set the scrollbars visibility to Auto:
XAML
<telerik:RadTreeView x:Name="radTreeView3" ScrollViewer.HorizontalScrollBarVisibility="Auto" ScrollViewer.VerticalScrollBarVisibility="Auto">
</telerik:RadTreeView>C#
private void EnableScrollBars()
{
ScrollViewer.SetHorizontalScrollBarVisibility(radTreeView, ScrollBarVisibility.Auto);
ScrollViewer.SetVerticalScrollBarVisibility(radTreeView, ScrollBarVisibility.Auto);
}
