Hi,
I have the following control-structure:
Everything works as expected, with ajax postbacks and updates in page_usercontrol3 being correctly handled.
Niow, I want to add a radajaxmanagerproxy and ajaxsettings to the other page_usercontrols. But, when I add the proxy and settings to any of the other controls to handle the button click, I get a client-side ajax error that says:
This error seems to be pointing to a field on the page_usercontrol3 control, which works perfectly well on it's own, but something goes wrong when handing postbacks on the other multipage contents.
Can you please give me a steer as to what is going on here?
I am not using the loadondemand style multipages. If I do, I get the same problem but worse, as it happens no matter which tab I go to.
Thanks.

Microsoft JScript runtime error: Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_ContentPlaceHolder1_tabs1_MyContent_txtMyInputPanel'. If it is being updated dynamically then it must be inside another UpdatePanel.
This error seems to be pointing to a field on the page_usercontrol3 control, which works perfectly well on it's own, but something goes wrong when handing postbacks on the other multipage contents.
