Protected Overridable Sub OnSizeChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Size) _
) 

Visual Basic (Usage)	Copy Code
Dim instance As MagnifyGlass Dim e As RoutedPropertyChangedEventArgs(Of Size)   instance.OnSizeChanged(e)

protected virtual void OnSizeChanged( 
   RoutedPropertyChangedEventArgs<Size> e
)

protected:
virtual void OnSizeChanged( 
   RoutedPropertyChangedEventArgs<Size>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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

Target Platforms: Windows 2000, Windows XP, Windows Server 2003 family, Windows Server 2008 family
