The RadTreeView adds a CSS class to selected nodes "rtSelected".  Is it possible to fire an event then, since you know when you are adding that class?

If I were to do a jQuery each on the <li> elements and subscribe to changes in the attribute "Class" I could probably mimic similar behavior.  

I have noticed this feature has been desired for several years.  
The work-arounds suggested by your staff are basically to capture onKeyPressing event and check for a newly selected node after a setTimeout.  This works but is more like a hammer to kill a fly.

Thank you
