Valor da Propriedade

Type: System.Web.UI.WebControls.ViewCollection

Um ViewCollection que representa uma coleção de controles View dentro de um controle MultiView. O padrão é null.

Use this property to programmatically manage the T:System.Web.UI.WebControls.View controls in a T:System.Web.UI.WebControls.MultiView control.

The following example demonstrates how to programmatically add T:System.Web.UI.WebControls.View controls to a T:System.Web.UI.WebControls.MultiView control. After each T:System.Web.UI.WebControls.View control is created, the MultiView.Views.Add() syntax is used to add the T:System.Web.UI.WebControls.View control to the T:System.Web.UI.WebControls.ViewCollection collection of the T:System.Web.UI.WebControls.MultiView control.
