ListObject.OriginalDataRestored 事件

當使用者執行不允許的動作時發生，ListObject 控制項接著會還原至原始狀態。

命名空間：  Microsoft.Office.Tools.Excel
組件：  Microsoft.Office.Tools.Excel (在 Microsoft.Office.Tools.Excel.dll 中)

語法

'宣告
Event OriginalDataRestored As OriginalDataRestoredEventHandler

event OriginalDataRestoredEventHandler OriginalDataRestored

備註

會引發這個事件之動作的範例，是使用者對唯讀的資料進行變更。 ListObject 控制項會復原變更並以原始值取代。

這個事件以列舉型別 (Enumeration ) 方式提供資訊，列舉型別中包含已還原的項目以及原因。

範例

下列程式碼範例會建立 DataTable 和 ListObject，並將 ListObject 繫結至 DataTable。 接著會建立 OriginalDataRestored 事件處理常式。 若要測試事件，請在工作表 1 的 ListObject 上方的資料行字母上按一下滑鼠右鍵，然後在捷徑功能表中按一下 [刪除]。 事件處理常式會取代欄和欄標題資料，並針對每個動作顯示訊息。
