The last time you asked this question, I posted a detailed answer along  
with a link to another post I'd written as a response to a very similar  
question asked by someone else.

You replied that the information appeared helpful and that you would try  
using it.

The TreeView and TreeNode classes haven't changed since I made that post,  
so there's not really anything new anyone can offer.  What about the  
previous information provided to you have you been having trouble with?

p.s. The thread's name was "Unique identifier in every treenode".  For  
some reason, while it's still in my local newsgroup message cache, I  
cannot find that thread in Google Groups.  I don't suppose anyone has any  
idea why that is, do that?  It seems to be in all sorts of other archives  
of this newsgroup (do a regular web search on Google and you'll find it).  
But not in the Google Groups archive.  Very odd.
