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