ObjectList.AutoGenerateFields 属性

  • 参考

定义

命名空间:
System.Web.UI.MobileControls
程序集:
System.Web.Mobile.dll

指定字段是否必须自动由数据生成。 启用后，数据的每个公共属性都成为控件的一个字段。 默认值是 true。 此 API 已废弃不用。 有关如何开发 ASP.NET 移动应用程序的信息，请参阅 移动应用 & 具有 ASP.NET 的网站。

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

属性值

Boolean

如果自动从数据生成字段，则为 true；否则为 false。

属性
BindableAttribute BrowsableAttribute

示例

下面的代码示例演示如何在 控件的“详细信息”视图中ObjectList使用 AutoGenerateFields 属性以静态方式将字段与其集合相关联。

注意

下面的代码示例使用单文件代码模型，如果直接复制到代码隐藏文件中，可能无法正常工作。 必须将此代码示例复制到扩展名为 .aspx 的空文本文件中。 有关详细信息，请参阅 ASP.NET Web Forms页代码模型。

注解

当 为 时 true，对象列表处理集合中的 ObjectListFieldCollection 字段顺序。 在 时 false，必须指定字段的顺序， DataItem 并将 属性设置为绑定到数据源。
