Hi i have a problem with the TreeView Control. I use framework 2.0, asp net c#, ajax.
In a webForm, i have register a UserControl.ascx that inside has a dialog control. In dialog's content template there is a TreeView that i populate in dinamic way. When i use the first time,there is not a problem, but i use the second time, (use the method Treeviw.nodes.clear() for delete the presents nodes), the TriewView is populate but i click on the button present in dialog's content template for excute a routine, appears a error text "Argument of postback o callback don't valid".
This erron don't appears if i don't use the methos Treeviw.nodes.clear().
Thank you

Hi Metoda,
What version of the DLL do you use? We recently fixed a problem related to view state. So you might want to give the latest build (2007.1.43) a try. If that does not fix it, please cretae a reproducing sample for us and we would be happy to look into it.
Thanks

Hi Metoda,
We would need to you create a reproducing project for us because obviously your code references some other class and also your database, so we can't run it here. Unless we can load it and run it at here to see the error, it will be almost impossible for us to identify the root cause.
Thanks
