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

The WindowClosedEventArgs type exposes the following members.

Public methodWindowClosedEventArgsInitializes a new instance of the WindowClosedEventArgs class.

Public propertyEventIdGets the event identifier. (Inherited from AutomationEventArgs.)

Public methodEquals(Object)Determines whether the specified object is equal to the current object. (Inherited from Object.)
Public methodGetHashCodeServes as the default hash function. (Inherited from Object.)
Public methodGetRuntimeIdRetrieves the UI Automation runtime identifier (ID) associated with this event.
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

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be used to obtain information about the window that has closed, because the corresponding UI Automation element is no longer valid.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.
