Re: Treeview Undo

["Douglas A Wolfe" <dougwolfejr gmail com>]

I was actually using the treeview to store the data.  It is a small
dataset and then writing the data to an xml file...so I was looking to
make a generic undo.

But  I guess I could write a more specific undo for the data I am
storing.   That would be pretty easy.  Thanks for your help.

PS.  Sorry I picked the wrong list.
