El evento se produce cuando el usuario hace clic en un botón de un control ToolBar. La propiedad Button contiene el ToolBarButton con la información sobre el botón en el que se hizo clic.
En el siguiente ejemplo se crea una instancia de un objeto ToolBar y de tres controles ToolBarButton. Los botones de barra de herramientas se asignan a la colección de botones, la colección se asigna a la barra de herramientas y ésta se agrega al formulario. En el evento ButtonClick de la barra de herramientas, se evalúa la propiedad Button de ToolBarButtonClickEventArgs y se abre el cuadro de diálogo correspondiente. Este código supone que se ha creado una instancia de Form, OpenFileDialog, SaveFileDialog y PrintDialog.
