OnHeaderBackgroundChanged Method

protected virtual void OnHeaderBackgroundChanged( 
   RoutedPropertyChangedEventArgs<Color> e
)

'Declaration
 
Protected Overridable Sub OnHeaderBackgroundChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of Color) _
) 

'Usage
 
Dim instance As AnnObject
Dim e As RoutedPropertyChangedEventArgs(Of Color)
 
instance.OnHeaderBackgroundChanged(e)

protected:
virtual void OnHeaderBackgroundChanged( 
   RoutedPropertyChangedEventArgs<Color>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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