PropertyChangedEventHandler Delegate

Represents the method that will handle the PropertyChanged event raised when a property is changed on a component.

[Visual Basic]
Public Delegate Sub PropertyChangedEventHandler( _
   ByVal sender As Object, _
   ByVal e As PropertyChangedEventArgs _
public delegate void PropertyChangedEventHandler(
   object sender,
   PropertyChangedEventArgs e
public __gc __delegate void PropertyChangedEventHandler(
   Object* sender,
   PropertyChangedEventArgs* e

[JScript] In JScript, you can use the delegates in the .NET Framework, but you cannot define your own.

Parameters [Visual Basic, C#, C++]

The declaration of your event handler must have the same parameters as the PropertyChangedEventHandler delegate declaration.

The source of the event.
A PropertyChangedEventArgs that contains the event data.


When you create a PropertyChangedEventHandler delegate, you identify the method that will handle the event. To associate the event with your event handler, add an instance of the delegate to the event. The event-handler method is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
