force refresh on control in master page

[John]

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1"  runat="server" />
<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server" >
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="RadGrid1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="RadGrid1" LoadingPanelID="RadAjaxLoadingPanel1" />
                <telerik:AjaxUpdatedControl ControlID="txtSelectedValues" LoadingPanelID="RadAjaxLoadingPanel1" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

So I have the following setting in a user control.  Now in a master page, I have this control and another control (say control 2).  What I want is to update control 2 when the user control get a select index change event.  I can fire the event and set the control 2 but it does not refresh cause it is not listed in the updatedcontrol.  So my question is.
1) can controls from a master page be added to a list of updated controls in the user control.  If so, how
2) Is there a way to force the update (override the ajax setting) in the master page so that it recognizes the refresh of control 2.

Thanks for any help, suggestions.

Hello John,

The desired functionality can be easily achieved by adding AjaxSettings programmatically.
You can find a sample project demonstrating how it works attached to this message.

I hope it helps.
