概述：Multiview和View控件使用事例

MultiView 和 View 控件和制作出选项卡的效果，MultiView 控件是一组 View 控件的容器。使用它可定义一组 View 控件，其中每个 View 控件都包含子控件。

如果要切换视图，可以使用控件的ID或者View控件的索引值。在 MultiView 控件中，一次只能将一个 View 控件定义为活动视图。如果某个 View 控件定义为活动视图，它所包含的子控件则会呈现到客户端。可以使用 ActiveViewIndex 属性或SetActiveView 方法定义活动视图。如果 ActiveViewIndex 属性为空，则 MultiView 控件不向客户端呈现任何内容。如果活动视图设置为MultiView 控件中不存在的 View，则会在运行时引发 ArgumentOutOfRangeException。

一些常用的属性、方法：

ActiveViewIndex属性：用于获取或设置当前被激活显示的View控件的索引值。默认值为－1，表示没有View控件被激活。

SetActiveView方法：用于激活显示特定的View控件。

4个静态只读字段：若要允许用户在 MultiView 控件中的 View 控件之间进行导航，可将 LinkButton 或 Button 控件添加到每个 View 控件。若要利用 MultiView 控件对当前活动 View 进行自动更新，请将按钮或链接按钮的 CommandName 属性设置为与所需导航行为对应的命令名字段的值，这些命令名字段如下：PreviousViewCommandName、NextViewCommandName、SwitchViewByIDCommandName 或 SwitchViewByIndexCommandName。

ActiveViewChanged事件：当视图切换时被激发。
