OnPropertyChanged Method

Summary

Syntax

C++/CLI

Java

Python

public virtual void OnPropertyChanged( 
   AnnPropertyChangedEventArgs e 
)

protected void onPropertyChanged(AnnPropertyChangedEvent event)

public:  
   virtual void OnPropertyChanged( 
      AnnPropertyChangedEventArgs^ e 
   )

def OnPropertyChanged(self,e):

Parameters

e
AnnPropertyChangedEventArgsEvent data

Remarks

Raising an event invokes the event handler through a function. The OnPropertyChanged method also allows derived classes to handle the event without attaching a function to the event. 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.
