通过

Repeater.DataMember 属性

  • 参考

定义

命名空间:
System.Web.UI.WebControls
程序集:
System.Web.dll

获取或设置 DataSource 中要绑定到控件的特定表。

public:
 virtual property System::String ^ DataMember { System::String ^ get(); void set(System::String ^ value); };
public virtual string DataMember { get; set; }
member this.DataMember : string with get, set
Public Overridable Property DataMember As String

属性值

String

指定 DataSource 中的表的字符串。

示例

以下示例演示如何使用DataMember属性指定要绑定到控件Repeater的DataSource表。

注解

如果属性指定的 DataSource 数据源包含多个数据源，请使用该 DataMember 属性指定要绑定到控件的特定源。 例如，如果有多个 System.Data.DataSet 表，则必须指定要绑定到控件的表。 指定数据源后，使用 DataBind 该方法将数据源绑定到控件。

此属性的值以视图状态存储。
