)
Visual Basic (Usage)Copy Code
Dim instance As ImageList
Dim e As RoutedPropertyChangedEventArgs(Of ImageListViewStyle)
 
instance.OnViewStyleChanged(e)
C# 
protected virtual void OnViewStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListViewStyle> e
)
Managed Extensions for C++ 
protected: virtual void OnViewStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListViewStyle> e
)
C++/CLI 
protected:
virtual void OnViewStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListViewStyle> e
)

Parameters

Remarks

Raising an event invokes the event handler through a delegate.

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

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Vista, and Windows Server 2003 family
