GridView >PagerTemplate> 頁碼

若要為頁導航行指定自訂模板，先要在 GridView 控制項的開始標記和結束標記之間放置 <PagerTemplate> 標記。然後可以在開始和結束
<PagerTemplate> 標記之間列出模板的內容。若要控制頁導航行的外觀，請使用
PagerStyle 屬性。

通常，將按鈕控制項添加到頁導航模板以執行分頁操作。單擊 CommandName 屬性設定為“Page”的按鈕控制項時，GridView 控制項會執行分頁操作。按鈕的
CommandArgument 屬性確定要執行的分頁操作的類型。下表列出了 GridView 控制項支援的命令參數值。

 

CommandArgument 值	說明
“Next”	導航至下一頁。
“Prev”	導航至上一頁。
“First”	導航至第一頁。
“Last”	導航至最後一頁。
整數值	導航至指定頁碼。
