This tutorial will walk you through how you can use Flyout Screen.
The Flyout screen can be activated through the RadFlyoutManager.Show() method. This method accepts two parameters. The first one is the control which the flyout will appear on top of it. The second parameter is the type of user control that will be used as content. The flyout screen can be used as a notification pop-up to notify for long-running operations. The second option is to be used in scenarios where additional information is required from the end user to continue using the application. In both cases, we can close the flyout screen by calling the RadFlyoutManager.Close() static method.
