Without a setter options are limited.  I am using a TreeView as a Prism 'navigation hub'.  My users traverse the TreeView and then I use Prism to navigate to a View in a Region loaded with the data from the TreeView SelectedItem.  But if the user makes changes and does not save them, and uses the TreeView to navigate away, I pop up a modal control and if the user cancels navigation I can get Prism to leave the 'dirty' view active, but I cannot get the TreeView SelectedItem to roll back.  Even if I save the previous SelectedItem and handle the Prism NavigationCallback, I cannot set the TreeView SelectedItem back.  So the UI looks terrible.  The TreeView is out of sync with the 'dirty' view.  This cannot be shipped.  What's a developer to do?
