I've no long taken over an app and something that's puzzling me is it seems the previous develop has registers controls in the RadAjaxManager like this? Is it an appropriate use of the manager to register controls in this way? Registering the AjaxManager to itself to update other controls?!?
<telerik:RadAjaxManager ID="AjaxManager" runat="server" OnAjaxRequest="AjaxManager_AjaxRequest" EnablePageHeadUpdate="false">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="AjaxManager">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="pnlAttendStatus" />
</UpdatedControls>
</telerik:AjaxSetting>
</telerik:RadAjaxManager>
