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