Comentarios

Cuando se crea un delegado DataGridViewSortCompareEventHandler, se identifica el método que controlará el evento.When you create a DataGridViewSortCompareEventHandler delegate, you identify the method that will handle the event. Para asociar el evento al controlador, se debe agregar una instancia del delegado al evento.To associate the event with your event handler, add an instance of the delegate to the event. Siempre que se produce el evento, se llama a su controlador, a menos que se quite el delegado.The event handler is called whenever the event occurs, unless you remove the delegate. Para obtener más información sobre los delegados de controladores de eventos, vea controlar y provocar eventos.For more information about event-handler delegates, see Handling and Raising Events.
