WindowClosedEventArgs Class

Contains information about the event that is raised when a window is closed.

Namespace:  System.Windows.Automation
Assembly:  UIAutomationTypes (in UIAutomationTypes.dll)

public sealed class WindowClosedEventArgs : AutomationEventArgs

To subscribe to window-closed events, call AddAutomationEventHandler, specifying WindowClosedEvent in the eventId parameter and supplying an UI Automation event handler that takes a WindowClosedEventArgs parameter.

When your application receives a window-closed event, the sender parameter of the event handler cannot be used to obtain information about the window that has closed, because the corresponding UI Automation element is no longer valid.

For example code, see GetRuntimeId.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
