字段值
示例
下面的代码示例演示如何使用 MultiView 控件创建基本调查。 每个 View 控件都是单独的调查问题。 PreviousViewCommandName和 NextViewCommandName 字段用于在调查中的上一个控件和下一个View控件之间提供自动导航。 如果用户单击最后一个View调查中的“重新获取调查”按钮,则将SwitchViewByIDCommandName字段与命令参数“Page1”一起使用,将用户重定向回调查的第一个View。
注意
下面的代码示例使用单文件代码模型,如果直接复制到代码隐藏文件中,可能无法正常工作。 必须将此代码示例复制到扩展名为 .aspx 的空文本文件中。 有关 Web 窗体代码模型的详细信息,请参阅 ASP.NET Web 窗体页代码模型。

注解
SwitchViewByIDCommandName使用 字段表示“SwitchViewByID”命令名称。
可以使用此字段的值来利用 MultiView 控件对活动 View 控件的自动更新。 例如,如果控件 View 包含一个在单击时导航到第一个 ButtonView 的控件,则可以将 CommandName 属性设置为字段的值 SwitchViewByIDCommandName ,即“SwitchViewByID”。 将 CommandArgument 属性设置为控件中MultiView第一个 View 的 ID,例如“Page1”。 这会导致控件在 MultiView 单击按钮时自动将“Page1”设置为活动 View 状态。
