El RowDeleted evento se desencadena cuando se hace clic en el botón eliminar de una fila, pero GridView después de que el control elimine la fila.The RowDeleted event is raised when a row's Delete button is clicked, but after the GridView control deletes the row. Esto le permite proporcionar un método de control de eventos que realiza una rutina personalizada, como comprobar los resultados de la operación de eliminación, siempre que se produzca este evento.This enables you to provide an event-handling method that performs a custom routine, such as checking the results of the delete operation, whenever this event occurs.

Un GridViewDeletedEventArgs objeto se pasa al método de control de eventos, lo que permite determinar el número de filas afectadas y cualquier excepción que se haya producido.A GridViewDeletedEventArgs object is passed to the event-handling method, which enables you to determine the number of rows affected and any exceptions that might have occurred. También puede indicar si la excepción se controló en el método de control de eventos estableciendo la ExceptionHandled propiedad GridViewDeletedEventArgs del objeto.You can also indicate whether the exception was handled in the event-handling method by setting the ExceptionHandled property of the GridViewDeletedEventArgs object.
