I have a typical Masterpage/content page scenario.
I have the following code setup where I am executing a AjaxRequest and wish to them update the RadGrid Control.  The documentation says that when this occurs to setup the AjaxManager as the calling control.

In this case I am using a proxy so I am substituing it here instead of the master page AjaxManager.  But it doesn't appear to trigger an update of the grid.

If I hard code the MasterPage's AjaxManager control Id in then it works.  The thing that is bugging me is I should not need to know the name of the control in the master, what happens if it changes?  Is there a way to not tightly couple the controlId to the masterPage and use the proxy controlId instead?



<telerik:RadCodeBlock>
<script type="text/javascript">
var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>");
ajaxManager.AjaxRequest(args);
</script>
</telerik:RadCodeBlock>

<asp:ScriptManagerProxy runat="server" ID="uxScriptManagerProxy"></asp:ScriptManagerProxy>
<telerik:RadAjaxManagerProxy ID="uxRadAjaxManagerProxy" runat="server">
       <AjaxSettings>
           <telerik:AjaxSetting AjaxControlID="uxTasksRadGrid">
               <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="uxTasksRadGrid" LoadingPanelID="RadAjaxLoadingPanel1"/>
               </UpdatedControls>
           </telerik:AjaxSetting>

      <telerik:AjaxSetting AjaxControlID="uxRadAjaxManagerProxy">
         <UpdatedControls>
            <telerik:AjaxUpdatedControl ControlID="uxTasksRadGrid" LoadingPanelID="RadAjaxLoadingPanel1"></telerik:AjaxUpdatedControl>
         </UpdatedControls>
      </telerik:AjaxSetting>

       </AjaxSettings>
   </telerik:RadAjaxManagerProxy>



(I also tried setting the ID="<%= RadAjaxManager.GetCurrent(Page).ClientID %> but that didn't appear to work either)

Any help appreciated!.

Hello Jafin,

Does the master AjaxManager contain a setting as the initiator being itself and the updated control being the grid? This is needed since you are actually performing a custom ajax request on the master manager, not the proxy manager. The following line obtains the instance to the master manager and performs an ajax request.

var ajaxManager = $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>"); 
ajaxManager.AjaxRequest(args); 

If the master manager contains the appropriate setting it will update the grid control.

Hope this helps!

Best wishes,
