I have given up my attempts at a WebTree in an WARP.  The tree was working fine, but server calls (through ICallBackEventHandler) on subsequent selections were getting eaten somewhere (by Warp I think, but not sure).  For that reason, and other posts that say you really should only use Warp for Framework 1.0 applications, I am going to switch over to UpdatePanels.

 Is there a good example of this out there somewhere???

 My initial attempt is failing!  The page appears to be reloaded each update.  I have the DemandLoadComplete logic (described in other posts) and that is never firing!

My code is somewhat complicated, so I can understand why it may not be working.  I have a page with UltraWebListBar with each Group dynamically created with a Web Control which contains a WebTree.  I have tried wrapping each WebTree in an UpdatePanel, and also wrapping the UltraWebListBar in an UpdatePanel, but each time the entire page is cleared and redisplayed.  Of course I only want an individual WebTree repopulated.

Any examples along this line would be appreciated!

Thanks!
