OnItemStyleChanged Method

Summary

Syntax

C++

protected virtual void OnItemStyleChanged( 
   RoutedPropertyChangedEventArgs<ImageListItemStyle> e 
)

  
Protected Overridable Sub OnItemStyleChanged( _ 
   ByVal e As RoutedPropertyChangedEventArgs(Of ImageListItemStyle) _ 
)

protected: 
virtual void OnItemStyleChanged(  
   RoutedPropertyChangedEventArgs<ImageListItemStyle>^ e 
)

Parameters

e
A RoutedPropertyChangedEventArgs that contains the event data.

Remarks

Raising an event invokes the event handler through a delegate.

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