Hello,

A possible reason the described error to appear could be if you have set ClientIDMode to static for the controls that are included in the Ajax settings. Please make sure that the control which is triggerring the ajax request (the one specified in the AjaxControlID property of the RadAjaxManager) has its ControlIDMode set to a value different from Static and let us know about the result.
