There are some workarounds on the net around, including some really ugly ones (like loading the whole tree in background asyncronously and trying to display the derired node :) ), but the best one which I could find, is to create a viewmodel (see for MVVM pattern if interested), add an IsSelected property to it, and bind it to the IsSelected property of the related treenode.

Then you can simply select (or even expand) the related items via your viewmodel, which is pretty much under your control.

It sounds a bit complicated this way, but it is explained pretty well on Bea Stollnitz's blog:
