I have a radWindowManager on my page, it is used to allow edits and additions of items in my gridview on the main page.
using the OnClientClose property of the RadWindow i am calling __doPostBack('UpdatePanel1',''); to refresh the updatepanel which contains my gridview.
i get the following error...
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request
it works fine if i dont use a radwindowmanager and just use a basic popup window.
