ObjectList.AutoGenerateFields 屬性

  • 參考

定義

命名空間:
System.Web.UI.MobileControls
組件:
System.Web.Mobile.dll

指定是否必須從資料自動產生欄位。 啟用時，資料的每個公用 (Public) 屬性會變成控制項的欄位。 預設值是 true。 這個 API 已經過時。 如需如何開發 ASP.NET 行動應用程式的資訊，請參閱 mobile Apps & Sites with ASP.NET。

public:
 property bool AutoGenerateFields { bool get(); void set(bool value); };
[System.ComponentModel.Bindable(false)]
[System.ComponentModel.Browsable(true)]
public bool AutoGenerateFields { get; set; }
[<System.ComponentModel.Bindable(false)>]
[<System.ComponentModel.Browsable(true)>]
member this.AutoGenerateFields : bool with get, set
Public Property AutoGenerateFields As Boolean

屬性值

Boolean

如果從資料自動產生欄位則為 true，否則為 false。

屬性
BindableAttribute BrowsableAttribute

範例

下列程式代碼範例示範如何使用 AutoGenerateFields 屬性，在控件的 [詳細數據] 檢視中，以靜態方式將字段與其集合產生 ObjectList 關聯。

注意

下列程式代碼範例會使用單一檔案程式代碼模型，如果直接複製到程式代碼後置檔案，可能無法正常運作。 此程式代碼範例必須複製到擴展名為 .aspx 的空白文本檔。 如需詳細資訊，請參閱 ASP.NET Web Forms 頁碼模型。

備註

當 為 時 true，物件清單會處理集合中的 ObjectListFieldCollection 欄位順序。 當 為 時 false，您必須指定欄位的順序，並設定 DataItem 屬性以系結至數據源。
