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