TreeView Question (C#)

I am having a problem with the TreeView control. What I am trying to
do, *should* be simple.

When the user selects a node in my TreeView, I first check to see if
the data for the object referenced by that node has changed. If it has,
I want to give the user the option of either selecting the next node in
the tree, or canceling, in which case the next node is not selected.
The tree remains as it was, with the original node selected. (I hope
this makes sense - it's a bit difficult to explain).

Anyway, I've been playing around with BeforeSelect, AfterSelect, etc.
and getting nowhere.

Does anyone have an idea how this might be done? I've pretty much
exhausted all of mine.

Thanks!
