Thanks for your reply Evgeny,
I am using FlyTreeView for ASP.NET 2.0. I found the code posted in http://www.9rays.net/forums/viewtopic.php?t=1102&highlight=refresh+node to work properly. Yet, it's quite possible there is a better way to do it. If so, I'd be thankful for any pushing into the right direction.
