Leadtools.Windows.Controls Namespace > ImageBox Class : OnFlipChanged Method |
protected virtual void OnFlipChanged( RoutedPropertyChangedEventArgs<bool> e )
'Declaration Protected Overridable Sub OnFlipChanged( _ ByVal e As RoutedPropertyChangedEventArgs(Of Boolean) _ )
'Usage Dim instance As ImageBox Dim e As RoutedPropertyChangedEventArgs(Of Boolean) instance.OnFlipChanged(e)
protected: virtual void OnFlipChanged( RoutedPropertyChangedEventArgs<bool>^ e )
Raising an event invokes the event handler through a delegate.
The OnFlipChanged 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 OnFlipChanged in a derived class, be sure to call the base class's OnFlipChanged method so that registered delegates receive the event.
