Changing Status during RadAjaxLoadingPanel in process

[JD.]

I have following code. 

1.  What I want to achieve is, to keep updating label2 as program statements proceeds eg.  "Loading,.... ", "Connecting....."
"Applying Changes......"   "Done..".   The Idea is to keep user inform about the current status , when processing takes longer time.

<telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" Skin="Telerik" >

<asp:Label ID="Label2" runat="server" ForeColor="Red">Loading... </asp:Label>

<asp:Image ID="Image1" runat="server" Width="224px" Height="48px" ImageUrl="~/Loading.gif">

</asp:Image>

</telerik:RadAjaxLoadingPanel>


Following is my code behind.

protected void RadGrid1_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
     {
         Label2.Text = "Connecting to Source";
 .........  Long code to retrieve data from DB into UC datasource.
         RadGrid1.DataSource = uc;
         Label2.Text = "Apply Results.";
     }

But this does not seem to work...... Is there a better workarond ?

Hi J.,

This cannot be achieved with ajax as in this case the controls are updated on the client only once, after the ajax request finishes.
