備註
利用這個 Row 屬性來程式化存取 FormViewRow 代表資料列的物件。 資料列包含根據目前模式（由 CurrentMode 屬性指定）所渲染的模板不同內容。 你只能存取目前模式的範本內容。 下表顯示每種模式所使用的範本。
| 模式 | 已渲染的範本 |
|---|---|
| Edit | EditItemTemplate |
| 插入 | InsertItemTemplate |
| 唯讀 | ItemTemplate |
備註
該 Row 屬性僅 FormView 在控制項建立事件資料 ItemCreated 列後才可用。
這個特性通常用於需要程式化操作資料列時，例如新增自訂內容時。 任何屬性 Row 的修改必須在 FormView 控制項被資料綁定後執行;否則， FormView 控制項會覆寫所有變更。
