Ajax / First Look

Configurator


Change Background Position:

  • 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.
