Ejemplos

En el ejemplo siguiente se crea una instancia de un ToolBar control y tres ToolBarButton controles.The following example instantiates a ToolBar and three ToolBarButton controls. Los botones de la barra de herramientas se asignan a la colección de botones, la colección se asigna a la barra de herramientas y la barra de herramientas se agrega al formulario.The toolbar buttons are assigned to the button collection, the collection is assigned to the toolbar, and the toolbar is added to the form. En el ButtonClick caso de la barra de herramientas, Button se evalúa la propiedad de ToolBarButtonClickEventArgs y se abre el cuadro de diálogo adecuado.On the ButtonClick event of the toolbar, the Button property of the ToolBarButtonClickEventArgs is evaluated, and the appropriate dialog opened. En este código se supone que Form OpenFileDialog SaveFileDialog PrintDialog se ha creado una instancia de,, y.This code assumes that a Form, an OpenFileDialog, a SaveFileDialog, and a PrintDialog have been instantiated.
