Hi Rtech,

Could you please elaborate a bit more on the described issue. What is the message and the stack trace of the received runtime error? Additionally could you please verify that you do not have another RadAjaxManager on the page or in the MasterPage file if you use master pages?

Looking forward for your reply.

Regards,
