Syntax

'Declaration
Public MustOverride Event PropertyChanged As PropertyChangedEventHandler

public abstract event PropertyChangedEventHandler PropertyChanged

public:
virtual  event PropertyChangedEventHandler^ PropertyChanged {
    void add (PropertyChangedEventHandler^ value);
    void remove (PropertyChangedEventHandler^ value);
}

abstract PropertyChanged : IEvent<PropertyChangedEventHandler,
    PropertyChangedEventArgs>

JScript does not support events.

Implements

INotifyPropertyChanged.PropertyChanged

Remarks

This event implements the INotifyPropertyChanged interface. This event can be used to tell when a property on the model changes. It is also useful because INotifyPropertyChanged can be used by the data binding features of Windows Presentation Foundation (WPF).

You should disconnect events from items when you are finished with them. Otherwise, you can prevent the item from being clean up during garbage collection.
