備註
使用 方法， ChangeMode 以程式設計方式在編輯、插入和唯讀模式之間切換 FormView 控制項。 這個方法也會使用指定的模式來更新 CurrentMode 屬性。 下表列出不同的模式值。
| [模式] | 描述 |
|---|---|
FormViewMode.Edit |
控制項 FormView 處於編輯模式，可讓使用者更新記錄的值。 |
FormViewMode.Insert |
控制項 FormView 處於插入模式，可讓使用者將新記錄新增至資料來源。 |
FormView.ReadOnly |
控制項 FormView 處於唯讀模式，這是一般顯示模式。 |
注意
ModeChanged呼叫此方法時，不會引發 和 ModeChanging 事件。
