OnHeaderChanged Method

Summary

Occurs when the value Header property changes.

Syntax

C++

protected virtual void OnHeaderChanged( 
   RoutedPropertyChangedEventArgs<string> e 
)

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

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

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

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.
