complete noob question -- how to get the ajax spinner?

[Sammy]

I've copied and pasted multiple examples, but I always get an exception.

How do I get the "Loading..." ajax spinner image?

Here is my code? I'm starting out simple. All I'm doing is clicking a button to populate a grid.

Thanks!

   <form id="form1" runat="server">
<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

   <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest">
 <AjaxSettings>
      <telerik:AjaxSetting  AjaxControlID="Button2">
           <UpdatedControls>
              <telerik:AjaxUpdatedControl ControlID="RadGrid2" />
              <telerik:AjaxUpdatedControl ControlID="lblMessage" />
           </UpdatedControls>
      </telerik:AjaxSetting>
   </AjaxSettings>
</telerik:RadAjaxManager>
<telerik:RadButton ID="button2" runat=server Text="Go"></telerik:RadButton>



<asp:label ID=lblMessage runat=server></asp:label>
<telerik:RadGrid ID="RadGrid2" runat="server" AutoGenerateColumns="true" ></telerik:RadGrid>

   </form>

Hi sammy,

you have to declare a loading panel

 <telerik:RadAjaxLoadingPanel ID="_ralp1" runat="server" />

and then set it as generic for all ajax actions 

 <telerik:RadAjaxManager ID="_ram" runat="server" DefaultLoadingPanelID="_ralp1">


if you want specific loading panel per control you can set it at

<telerik:AjaxUpdatedControl ControlID="RadGrid2" LoadingPanelID="_ralp1" />
