Lines Support

The RadTreeView allows you to enable connected lines between the nodes of a treeview. By default the connecting lines between the nodes are not enabled (they are not visible). You should use a single property to do so - IsLineEnabled and set it to True.

<telerik:RadTreeView x:Name="radTreeView" IsLineEnabled="True">

You can also control the visibility of the lines between the root items (the items on the first level) of the treeview. This can be done with the IsRootLinesEnabled property of the treeview. The default value of this property is True

<telerik:RadTreeView x:Name="radTreeView" IsLineEnabled="True" IsRootLinesEnabled="False">
