備註

當屬性設定為 true) 時， (啟用分頁時 AllowPaging ，控制項中 FormView 會自動顯示稱為呼叫器資料列的額外資料列。呼叫器資料列包含控制項，可讓使用者巡覽至其他記錄，而且可以顯示在控制項的頂端、底部，或控制項的頂端和底部。 TopPagerRow使用屬性，以程式設計方式存取 FormViewRow 物件，該物件代表控制項中的 FormView 頂端頁面巡覽列。

注意

TopPagerRow只有在控制項在事件中 ItemCreated 建立頂端頁面巡覽列之後 FormView ，才能使用屬性。

當您需要以程式設計方式操作頂端頁面巡覽列時，例如新增自訂內容時，通常會使用這個屬性。對屬性所做的任何修改 TopPagerRow 都必須在控制項系結至資料之後 FormView 執行， FormView 否則控制項會覆寫任何變更。
