Leadtools.Windows.Controls Namespace > ImageList Class : OnItemImageSizeChanged Method |
protected virtual void OnItemImageSizeChanged( RoutedPropertyChangedEventArgs<Size> e )
'Declaration Protected Overridable Sub OnItemImageSizeChanged( _ ByVal e As RoutedPropertyChangedEventArgs(Of Size) _ )
'Usage Dim instance As ImageList Dim e As RoutedPropertyChangedEventArgs(Of Size) instance.OnItemImageSizeChanged(e)
protected: virtual void OnItemImageSizeChanged( RoutedPropertyChangedEventArgs<Size>^ e )
Raising an event invokes the event handler through a delegate.
The OnItemImageSizeChanged 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 OnItemImageSizeChanged in a derived class, be sure to call the base class's OnItemImageSizeChanged method so that registered delegates receive the event.
For C#/VB examples, refer to OnItemStyleChanged.
