The event handler receives an argument of type DesktopAlertClosedEventArgs containing data related to this event. The following DesktopAlertClosedEventArgs properties provide information specific to this event.

PropertyDescription
WindowInfo (Inherited from Infragistics.Win.Misc.DesktopAlertEventArgsBase)Returns a reference to the UltraDesktopAlertWindowInfo instance for which the event was fired.
Example
The following code sample demonstrates how the DesktopAlertClosed event can be used in conjunction with the ScreenLocation property of the UltraDesktopAlertShowWindowInfo class to show desktop alert windows at the same location as the last one that was shown.

For an overview of how to handle events in Visual Basic or Visual C#, see Event Handlers in Visual Basic and Visual C#. For specific information and code examples illustrating how to consume events in your application, see Consuming Events in the .NET Framework Developer's Guide.
