Protected Overridable Sub OnFontStyleChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of AnnFontStyle) _
) 

Visual Basic (Usage)	Copy Code
Dim instance As AnnRulerObject Dim e As RoutedPropertyChangedEventArgs(Of AnnFontStyle)   instance.OnFontStyleChanged(e)

protected virtual void OnFontStyleChanged( 
   RoutedPropertyChangedEventArgs<AnnFontStyle> e
)

protected:
virtual void OnFontStyleChanged( 
   RoutedPropertyChangedEventArgs<AnnFontStyle>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

The OnFontStyleChanged 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 OnFontStyleChanged in a derived class, be sure to call the base class's OnFontStyleChanged 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)
