Hierarchical Template Entire TreeView Width

[Johnathan]

When I use a Hierarchical Template for generating a TreeView the branches of the TreeView wont use the entire width of the TreeView, even when I use a Grid with a column of * width.  Is there a way to get the template content to make use of the entire width?

Hello Johnathan,

The content of the RadTreeViewItems is not stretched because the presenter that holds it is horizontally aligned to Left. In order to achieve your requirement and stretch the Grid defined in the treeview's ItemTemplate you can set the HorizontalContentAlignment property of the RadTreeViewItems to Stretch.

<telerik:RadTreeView.ItemContainerStyle>
	<Style TargetType="telerik:RadTreeViewItem">
		<Setter Property="HorizontalContentAlignment" Value="Stretch" />
	</Style>
</telerik:RadTreeView.ItemContainerStyle>

In addition to this I attached a sample solution where this logic is implemented.
