This demo illustrates the use of the DevExpress ASP.NET Loading Panel (ASPxLoadingPanel) control in modal mode.
Depending on the check box setting, the ASPxLoadingPanel can be displayed over the entire page or a specified HTML element. It is controlled by the ContainerElementID property.
In this demo, the ASPxLoadingPanel is displayed for a few seconds and hidden dynamically using client code in response to clicks on the Show Loading Panel button.
