updating a radgrid which is in a usercontrol

[Nazım]

Hi,
I cant manage to update a radgrid which is in a usercontrol. My ajaxmanager is in the mainform.

my usercontol is TaniUC 
I manage to fire ajaxrequest event from usercontol. But i can not update radgrid. I use TaniEkle(ID) which is a public func in my usercontol,add a row to my radgrid.
It is adding but not updating on screen.

protected void RadAjaxManager1_AjaxRequest(object sender, AjaxRequestEventArgs e)
        {
            if(e.Argument=="taniekle")
            {
                int ID = DataReader.GetInt32(Request.Form["grdTanilarDClickedRowIndex"]);
                if (ID > 0)
                 {
                     ucpTani.TaniEkle(ID);
                 }
                return;
            }
}

<telerik:RadAjaxManager ID="RadAjaxManager1" OnAjaxRequest="RadAjaxManager1_AjaxRequest"
       runat="server">
       <AjaxSettings>


           <telerik:AjaxSetting AjaxControlID="RadAjaxManager1">
               <UpdatedControls>
                  <telerik:AjaxUpdatedControl ControlID="grdHastalar" LoadingPanelID="RadAjaxLoadingPanel1" />
               </UpdatedControls>
           </telerik:AjaxSetting>
          <telerik:AjaxSetting AjaxControlID="grdHastalar" EventName="OnRowClick" >
               <UpdatedControls>
                   <telerik:AjaxUpdatedControl ControlID="TaniUC"  LoadingPanelID="RadAjaxLoadingPanel1" />
               </UpdatedControls>
           </AjaxSettings>
   </telerik:RadAjaxManager>

I found the answer. I wrote the Id of usercontrol is wrong. Adding it to updatecontrol solve my questions. 

<telerik:AjaxUpdatedControl ControlID="ucpTani"  LoadingPanelID="RadAjaxLoadingPanel1" />
