TreeView doesn't refresh unless restart VS2005

[Charlie@CBFC]

Hi:

My TreeView control is binding to XML using XMLDataSource control. Works
well. However when I add a new item to database and requery tree or restart
app, new item doesn't appear on tree. It's not until I restart VS2005 does
the tree refresh. Sounds like tree data is being cached or something. I've
tried nulling out things after tree databinds, but to no avail.

Thanks,
Charlie
