RadAjaxLoadingPanel supports skinning and you can change its skin by setting
the Skin property to the name of the respective skin. A BackgroundPosition
property enables you to position the loading image in the loading panel. The EnableSkinTransparency
property allows you to enable/disable default skin transparency.
Please note that the loading images that are currently embedded in the Telerik.Web.UI
assembly will not be available after Q1 2009.
