RadControls for ASP.NET AJAX
When configuring ajax settings, be it declaratively, or dynamically, you might need to set some of the
below properties to each of the updated controls:
LoadingPanelID - gets or sets the loading panel ID which is will be displayed over the updated control during ajax.
UpdatePanelHeight - determines what wil be the height of the ajax panel wrapped around the updated control. Useful when you need to set 100% high to the parent of the updated control.
UpdatePanelRenderMode - determines what wil be the ajax panel render mode. For more information see this article
