備註
設定 或 FooterTemplate 屬性時 FooterText ，頁尾資料列會顯示在 控制項底部 FormView 。 FooterRow使用 屬性，以程式設計方式存取 FormViewRow 代表頁尾資料列的物件。
注意
FooterRow只有在 控制項在 事件中 ItemCreated 建立頁尾資料列之後 FormView ，才能使用 屬性。
當您需要以程式設計方式動作頁尾資料列時，通常會使用這個屬性，例如新增自訂內容時。 在轉譯控制項之後 FormView ，必須對 屬性進行任何修改 FooterRow ;否則， FormView 控制項會覆寫任何變更。
若要控制頁尾資料列的樣式，請使用 FooterStyle 屬性。
