The LoadingPanelID property of RadXmlHttpPanel allows it to be hooked to a RadAjaxLoadingPanel, which will overlap the panel for the duration of the request. This could be used for requests that are expected to take some time to process on the server-side. For demonstration purposes in this example, Thread.Sleep is used in the in the XmlHttpPanel_ServiceRequest event on the server.
