Hi,
I have the same issue as highlighted in this thread: http://www.telerik.com/community/forums/wpf/docking/control-contextmenu-in-a-docking-radpane-does-not-show-up.aspx
However, setting the ContextMenuItemTemplate to null as shown in the documentation does not work
<
telerik:RadPane
ContextMenuTemplate
=
"{x:Null}"
