This example demonstrates various ways to display a default pop-up window.

Overview

The ASPxPopupControl creates a default pop-up window when the control's Windows collection is empty. You can change the default pop-up window's visibility on the server or client.

Set the ShowOnPageLoad property to true on the server to display the default pop-up window when a client browser loads the page.

Call one of the following client-side methods to show the default pop-up window:
