OnRectChanged Method

Summary

Occurs when the value Rect property changes.

Syntax

C++

protected virtual void OnRectChanged( 
   RoutedPropertyChangedEventArgs<Rect> e 
)

  
Protected Overridable Sub OnRectChanged( _ 
   ByVal e As RoutedPropertyChangedEventArgs(Of Rect) _ 
)

protected: 
virtual void OnRectChanged(  
   RoutedPropertyChangedEventArgs<Rect>^ e 
)

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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