注解

AlternatingItemTemplate使用属性为交替数据项定义自定义用户界面 (UI) 。模板 AlternatingItemTemplate 通常包含与模板相同的控件和内容 ItemTemplate ，但具有不同的外观来区分项。

若要以声明方式指定自定义模板，请在控件中添加ListView元素AlternatingItemTemplate。然后在开始标记和结束 <AlternatingItemTemplate> 标记之间添加控件和内容。若要显示数据源中的字段值，请使用数据绑定表达式。有关详细信息，请参阅数据绑定表达式概述。

若要创建自动选择、删除和编辑操作的按钮，请将按钮控件添加到模板。将其 CommandName 属性设置为下表中列出的值之一。

按钮类型	CommandName 值
删除	“Delete”
编辑	“编辑”
选择	“选择”
