Loading Panel

When the page control’s ASPxTabControlBase.AutoPostBack property is set to false, and the ASPxPageControl.EnableCallBacks property is set to true, the first activation of an inactive tabbed page initiates a callback to the server to obtain the page’s content. In this case, a specific loading panel is displayed as the newly activated page’s contents while waiting for a callback response.

A loading panel can be customized by using its style settings, specifying its text and image.
