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。
BottomPagerRow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 底部頁面巡覽列。
注意
只有在 BottomPagerRow 控制項在 事件中 ItemCreated 建立底部頁面巡覽列之後 FormView ，才能使用 屬性。
當您需要以程式設計方式操作底部頁面巡覽列時，例如新增自訂內容時，通常會使用這個屬性。 屬性的任何修改 BottomPagerRow 都必須在建立代表底部頁面巡覽列的物件之後 FormViewRow 執行;否則， FormView 控制項會覆寫任何變更。
