GridView >PagerTemplate> 页码

若要为页导航行指定自定义模板，先要在 GridView 控件的开始标记和结束标记之间放置 <PagerTemplate> 标记。然后可以在开始和结束 <PagerTemplate> 标记之间列出模板的内容。若要控制页导航行的外观，请使用 PagerStyle 属性。

通常，将按钮控件添加到页导航模板以执行分页操作。单击 CommandName 属性设置为“Page”的按钮控件时，GridView 控件会执行分页操作。按钮的 CommandArgument 属性确定要执行的分页操作的类型。下表列出了 GridView 控件支持的命令参数值。

 

CommandArgument 值	说明
“Next”	导航至下一页。
“Prev”	导航至上一页。
“First”	导航至第一页。
“Last”	导航至最后一页。
整数值	导航至指定页码。
