備註

ShowDeleteButton使用 屬性可指定是否在資料來源控制項中每個記錄的欄位中顯示 CommandField [刪除] 按鈕。 [刪除] 按鈕可讓您從資料來源中移除記錄。

注意

當資料繫結控制項與資料來源控制項搭配使用時， (例如 SqlDataSource 控制項) ，資料繫結控制項可以利用資料來源控制項的功能並提供自動刪除功能。 對於其他資料來源，您必須提供常式，以在資料繫結控制項的適當事件期間執行刪除作業。

ButtonType當欄位的 CommandField 屬性設定 ButtonType.Button 為 或 ButtonType.Link 時，請使用 DeleteText 屬性來指定要顯示 [刪除] 按鈕的文字。 或者，您可以先將 屬性設定 ButtonType 為 ButtonType.Image ，然後設定 DeleteImageUrl 屬性來顯示影像。
