Protected Overridable Sub OnFontSizeChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Double) _
) 

Visual Basic (Usage)	Copy Code
Dim instance As AnnCrossProductObject Dim e As RoutedPropertyChangedEventArgs(Of Double)   instance.OnFontSizeChanged(e)

protected virtual void OnFontSizeChanged( 
   RoutedPropertyChangedEventArgs<double> e
)

protected:
virtual void OnFontSizeChanged( 
   RoutedPropertyChangedEventArgs<double>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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

Target Platforms: Silverlight 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family, Windows Vista, Windows 7, MAC OS/X (Intel Only)
