I've checked out Eilon's blog on this error, tried everything he mentioned, and it still doesn't work. Also, I've added the "enablepartialrendering" to my script manager and it points me to another error that I can't seem to fix ("sys.webforms.pagerequestmanager is null...").
That being said, I have 2 pages in the same directory. Telerik AJAX controls work fine on one but do not work on the other, the one giving me this error. The 2 pages are set up identically, Telerik loading panels, ajax panels, radgrids, tab strips, multi-page viewers, the code behind...
I get the above error when I try clicking the "add new record" button.
What could the problem be? If I need to paste some code in here to diagnose, please let me know and I will do so. Thanks for taking the time out of your day to assist me.
