ListObject.Change 事件 (2007 系統)
更新: 2008 年 7 月
當 ListObject 控制項變更時發生。
命名空間: Microsoft.Office.Tools.Excel
組件: Microsoft.Office.Tools.Excel.v9.0 (在 Microsoft.Office.Tools.Excel.v9.0.dll 中)
語法
Public Event Change As ListObjectChangeHandler
Dim instance As ListObject
Dim handler As ListObjectChangeHandler
AddHandler instance.Change, handler
public event ListObjectChangeHandler Change
備註
如果 ListObject 控制項以執行程式或與使用者互動的方式進行變更時,即引發這個事件。
當儲存格在重新計算期間發生變更時,不會發生這個事件。
範例
下列程式碼範例會建立 ListObject 和 Change 事件處理常式。若要引發 Change 事件,請將文字加入至 ListObject 中的一個儲存格,然後按 ENTER 鍵。
這是示範文件層級自訂的版本。
