获取或设置数据源中的字段的名称，此名称包含要为 HyperLinkField 对象中的超链接标题显示的文本。

public:
 virtual property System::String ^ DataTextField { System::String ^ get(); void set(System::String ^ value); };

[System.ComponentModel.TypeConverter("System.Web.UI.Design.DataSourceViewSchemaConverter, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]
public virtual string DataTextField { get; set; }

[System.ComponentModel.TypeConverter("System.Web.UI.Design.DataSourceViewSchemaConverter, System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")]
public virtual string DataTextField { get; set; }

[<System.ComponentModel.TypeConverter("System.Web.UI.Design.DataSourceViewSchemaConverter, System.Design, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")>]

[<System.ComponentModel.TypeConverter("System.Web.UI.Design.DataSourceViewSchemaConverter, System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")>]
member this.DataTextField : string with get, set

Public Overridable Property DataTextField As String

属性值

String

数据源中的字段的名称，此名称包含要为 HyperLinkField 中的超链接标题显示的值。默认值为空字符串 ("")，表示尚未设置此属性。

属性: TypeConverterAttribute

注解

使用 DataTextField 属性指定要为对象中的 HyperLinkField 超链接标题显示的文本的字段的名称。

可以使用此属性将超链接标题设置为静态值，而不是使用 Text 此属性将超链接标题绑定到字段。使用此选项时，每个超链接共享相同的标题。

备注

DataTextField如果同时设置了和Text属性，则属性DataTextField优先。
