WPF Context menu doesn't bind to right databound item

Question

I have a problem when binding a command in a context menu on a usercontrol that is on a tab page. The first time I use the menu (right-click on the tab) it works great, but

Answer 1

I found this method using the Tag property very useful when binding from a context menu deep inside a control template:

This makes it possible to bind to any datacontext available to the control that the context menu was opened from. The context menu can access the clicked control through "PlacementTarget". If the Tag property of the clicked control is bound to a desired datacontext, binding to "PlacementTarget.Tag" from inside the context menu will slingshot you directly to that datacontext.
