Scenario:
Master page with no AjaxManager
Content page containing an AjaxManager and RadMultiPage control working with a RadTabStrip control
User control with an empty RadAjaxManagerProxy

User clicks a button in the user control, some server side code executes and then an event call is bubbled up to the content page.  This event updates a label on the content page.  I can see the code executing properly but the label doesn't get updated.  Tried various AjaxManager settings with no luck.

Condensed Content page aspx:

Hello Neil,

Please note that Single PageView or control added in PageView could not be added as AJAX initiator or updated control in the AJAX settings. The only possible approach is to add the whole MultiPage in the RadAjaxManager settings. See the topic below:

http://www.telerik.com/help/aspnet-ajax/ajax-tips-and-tricks.html

Therefore in your case you should add a settings in which the pnTabs updates itself and also updates the needed label. Give this a try and let me know if this helps.

All the best,
