Hi,
I have the following control-structure:

<master>

<radscriptmanager />

<radajaxmanager />

<page>

<radajaxmanagerproxy />

<tabs_usercontrol>

<radajaxmanagerproxy />

<radtabstrip />

<radmultipage>

<page_usercontrol1>

<button />

</page_usercontrol1>

<page_usercontrol2>

<button />

</page_usercontrol2>

<page_usercontrol3>

<radajaxmanagerproxy>

<ajaxsettings />

</radajaxmanagerproxy>

<radtextbox />

<button />

</page_usercontrol3>

<page_usercontrol4>

<button />

</page_usercontrol4>

</radmultipage>

</tabs_usercontrol>

</page>

</master>

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:

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.

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.
