ApplicationSettingsBase.OnPropertyChanged Method (Object, PropertyChangedEventArgs)


Raises the PropertyChanged event.

Namespace:   System.Configuration
Assembly:  System (in System.dll)

protected virtual void OnPropertyChanged(
	object sender,
	PropertyChangedEventArgs e


Type: System.Object

The source of the event.

Type: System.ComponentModel.PropertyChangedEventArgs

A PropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate. For more information, see NIB: Raising an Event.

The OnPropertyChanged method also allows derived classes to handle the event without attaching a delegate. This is the preferred technique for handling the event in a derived class.

Notes to Inheritors:

When overriding OnPropertyChanged in a derived class, be sure to call the base class's OnPropertyChanged method so that registered delegates receive the event.
