OnPropertyChanged Method

Summary

Syntax

C++

protected virtual void OnPropertyChanged( 
   string propertyName 
)

Protected Overridable Sub OnPropertyChanged( 
   ByVal propertyName As String 
)

protected:  
   virtual void OnPropertyChanged( 
      String^ propertyName 
   )

Parameters

propertyName

The property name.

Remarks

Raising an event invokes the event handler through a delegate. 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.

Note 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.
