A method that will handle the LayerBase.VisibleChanged event.
public delegate void LayerVisibleChangedEventHandler( object sender, LayerVisibleChangedEventArgs e );
Public Delegate Sub LayerVisibleChangedEventHandler( sender As Object, e As LayerVisibleChangedEventArgs )
The event source.
An LayerVisibleChangedEventArgs object that contains the event's data.
When creating a LayerVisibleChangedEventHandler delegate, you identify the method that will handle the corresponding event. To associate an event with your event handler, add a delegate instance to this event. The event handler is called whenever the event occurs, unless you remove the delegate. For more information about event handler delegates, see Events and Delegates in MSDN.
