備註

DefaultMode使用 屬性可指定控制項在執行更新、插入或取消作業之後,是否 FormView 傳回編輯、插入或唯讀模式。 根據預設, FormView 控制項會傳回唯讀模式;不過,您可以將此屬性設定為適當的值,讓控制項保持 FormView 編輯或插入模式。 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。
FormViewMode.ReadOnly 控制項 FormView 處於唯讀模式,這是一般顯示模式。

當控制項具有單一用途時 FormView ,通常會使用這個屬性,例如只插入或編輯記錄。
