注解

GroupTemplate使用 属性在 控件中创建平铺布局ListView。 在平铺表布局中,项目在一行中水平重复。 项的重复次数由 GroupItemCount 属性指定。

若要以声明方式为组容器指定模板,请在 控件中添加ListView元素GroupTemplate。 然后,可以将模板的内容添加到 GroupTemplate 元素。

属性 GroupTemplate 必须包含数据项的占位符,例如表单元格 (td) 、 divspan 元素。 此占位符必须将 runat 属性设置为“server”,并将 ID 属性设置为 属性的值 ItemPlaceholderID 。 在运行时,控件ListView将占位符替换为为 和 AlternatingItemTemplate 模板中的每个ItemTemplate项定义的内容。
