Display loading panel while page loads

Recently I started using DevExpress controls and am quite suppressed at how easy they are to be used. On one occasion the requirement was to show a loading text/gif until processing is completed on the server.
Here is how this can be achieved.

1. First place a "ASPxLoadingPanel" to show loading text

2. Add "ASPxCallbackPanel"

3. Add script block to show loading panel and send request for server side processing

4. Add server side processing code

protected void callbackPanel_Callback(object sender, CallbackEventArgsBase e)
{
}

That's it all done.
