下面的步骤描述移动 List 控件如何利用集合中的元素构造一个 MobileListItem 实例：
该控件检查是否已定义 DataTextField 或 DataValueField 属性。如果已定义，该控件将使用这些字段名来发现元素中的属性并设置 MobileListItem 实例的 Text 和 Value 属性。
如果既没有定义 DataTextField 属性也没有定义 DataValueField 属性，则控件将 MobileListItem 实例的 Text 和 Value 属性设置为元素的字符串表示形式（通过使用 ToString 方法）。
如果定义了 ItemDataBind 事件处理程序，则调用该处理程序。可以使用该处理程序来设置 MobileListItem 实例的属性。
提供默认呈现时，列表控件将以其 Text 属性表示 MobileListItem 实例。在模板化呈现中，模板可以呈现 MobileListItem 实例（或关联的数据绑定对象）的所需属性。
如果已设置 ItemsAsLinks 属性，List 控件会将项呈现为超链接。Text 属性的值将成为链接文本，而 Value 属性的值则成为目标 URL。
处理选择
如果列表很复杂（如对象数组），则无法通过选择直接访问选定项的成员。不过，如果适当地设计应用程序，则可以访问关联的对象。如果您正在创建一组对象来填充列表，则可以使该组成为全局数组，然后将返回值作为该数组的索引进行处理，如下面的代码示例所示。
