Try casting the item to a channel type. if that throws an error... probably not a channel

I found the solution. Convert Callback to DBLClick.vi  from the VI.LIB has a parameter Return Meet Filter Selection, if this is set to TRUE, I get the behavior I was looking for.  The parent folder will expand on a double click, and the root channels can only be selected.

Awesome! Glad to hear it. If you dont mind can you post the final VI for others to learn from?
