OnHeaderChanged Method (AnnObject)

protected virtual void OnHeaderChanged( 
   RoutedPropertyChangedEventArgs<string> e
)

'Declaration
 
Protected Overridable Sub OnHeaderChanged( _
   ByVal e As RoutedPropertyChangedEventArgs(Of String) _
) 

'Usage
 
Dim instance As AnnObject
Dim e As RoutedPropertyChangedEventArgs(Of String)
 
instance.OnHeaderChanged(e)

protected:
virtual void OnHeaderChanged( 
   RoutedPropertyChangedEventArgs<String^>^ e
) 

Parameters

e

A RoutedPropertyChangedEventArgs that contains the event data.

Raising an event invokes the event handler through a delegate.

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