I am getting the 'htmlfile:Unexpected call to method or property access' error while I select a Treeview node and click on a button on the second attempt. i.e first I select a node and click on the button which opens a Radwindow pop up and then when I close the Radwindow , I make a Ajax request on the parent page to refrsh the Treeview control. Once that is done , when I select some other node and click on the button (to update the information opening a Radwindow) , I get the above error mentioned. I read in several of your threads that It is related to IE 8 and the latest version of RadControls for ASP.NET AJAX resolves this issue. But I have the latest 2011 1Q SP2 version, but still it's not resolved.
