OnSizeChanged Method

protected virtual void OnSizeChanged( 
   RoutedPropertyChangedEventArgs<Size> e
)

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

'Usage
 
Dim instance As MagnifyGlass
Dim e As RoutedPropertyChangedEventArgs(Of Size)
 
instance.OnSizeChanged(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.
