Below you will see the demo of the problem I have.

I need from edittemplate of the Grid in ButtonControl to update Message Control in Master Page. If inside of the proxy I don't put

    
            <telerik:RadAjaxManagerProxy ID="ramProxyShow" runat="server">  
        
                <AjaxSettings> 
        
                    <telerik:AjaxSetting AjaxControlID="RadGrid1">  
        
                        <UpdatedControls> 
        
                            <telerik:AjaxUpdatedControl ControlID="RadGrid1" /> 
        
                        </UpdatedControls> 
        
                    </telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </telerik:RadAjaxManagerProxy>

I don't put AjaxSettings - everything is OK and works. But with it it doesn't.

Any suggestions?

Hello James,

Based on the supplied information, it is hard to determine what is causing this erroneous behavior. If the issue persists, it will be best if you open a formal support ticket, and send us a small working project, demonstrating your setup, and showing the unwanted behavior. We will debug it locally, and get back to you with more information on the matter.
