備註

Row使用 屬性，以程式設計方式存取 FormViewRow 代表資料列的物件。 資料列會根據屬性所指定的 CurrentMode 目前模式所呈現的範本，包含不同的內容 (屬性) 。 您只能存取目前模式的範本內容。 下表顯示每個模式所使用的範本。

模式 轉譯的範本
編輯 EditItemTemplate
插入 InsertItemTemplate
唯讀 ItemTemplate

注意

只有在 Row 控制項在 事件中 ItemCreated 建立資料列之後 FormView ，才能使用 屬性。

當您需要以程式設計方式運算元據列時，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 Row 都必須在控制項資料系結之後 FormView 執行;否則， FormView 控制項會覆寫任何變更。
