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.


The table below lists the main members which affect the appearance of loading panels and the way in which they function:
