Re: UpdatePanel .Net Treeview.PopulateOnDemand conflict?

Hi, has been a long time since this error occured, but I've got still the same problem in 2009... The TreeView works fine until I trigger another UpdatePanel on the page - after that, there no chance to expand nodes. I've got to do a complete postback, what I tried to avoid before the control...

Re: Treeview does not reflect changes made to it.

Treeview inside update panel adds nodes when expanded/collapsed
