PropertyChangingEventHandler Delegate

Represents the method that will handle the PropertyChanging event of an INotifyPropertyChanging interface.

Namespace:  System.ComponentModel
Assemblies:   System.ObjectModel (in System.ObjectModel.dll)
  System (in System.dll)

public delegate void PropertyChangingEventHandler(
	Object sender,
	PropertyChangingEventArgs e
)

Parameters

sender
Type: System.Object

The source of the event.

e
Type: System.ComponentModel.PropertyChangingEventArgs

A PropertyChangingEventArgs that contains the event data.

PropertyChangingEventHandler is introduced in the .NET Framework version 3.5. For more information, see .NET Framework Versions and Dependencies.

When you create a PropertyChangingEventHandler 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 is called whenever the event occurs, unless you remove the delegate. For more information about event-handler delegates, see Events and Delegates.
