I need a simple example of a Tunnel Routed Event tunnelling from a parent control to a child control. (THIS IS NOT REAL CODE) -- in fact, the deeper I go, the more I think that the XAML is wrong -- probably should NOT sign up for the tunnelled event in XAML on the child node (not sure?) <PARENT> <MyControl DoSomethingOnUserActio...

The goal is to have the TreeViewItem expand or collapse when it is double clicked. I have a style that applies an event handler for the MouseDoubleClick event to each TreeViewItem.
