Loading Panel

When the navbar's ASPxNavBar.AutoPostBack property is set to false and the ASPxNavBar.EnableCallBacks property is set to true, the first expansion of a collapsed NavBar group initiates a callback to the server, to obtain the group's content. In this case, a specific loading panel is displayed as the expanded group's contents while waiting for a callback response.

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