Hello,
I changed my project to Prometheus and I start getting a error like:
"Cannot find update panel with id: ctl00_ctl00_Content1_Button1"

The update control ControlID server side is ctl00_Content1_Button1 but in client side it’s wrongly formed. It seems to me that it depends from the relative path between the AjaxManager and the control to update.
Later I understood that this happens because I had the AjaxSetting on the AjaxRequest handler. The previous version of RadAjaxManager supported this perfectly, Prometheus does not. I must add the setting during OnLoad.

In my project the control to update depends of AjaxRequestEventArgs Argument. I think this is an important feature that you should implement in the future.

I added a small example showing the problem I described.

Best regards,
Tiago Veiga.
