Para ejecutar el código de ejemplo, péguelo en un proyecto que contenga una instancia de tipo HtmlDocument denominada HtmlDocument1 .To run the example code, paste it into a project that contains an instance of type HtmlDocument named HtmlDocument1. A continuación, asegúrese de que el controlador de eventos está asociado al MouseDown evento.Then ensure that the event handler is associated with the MouseDown event.

private void HtmlDocument1_MouseDown(Object sender, HtmlElementEventArgs e) {
