注解

ButtonType当 对象的 属性ButtonField设置为 Button 或 Link 值时，使用 Text 属性显示 中ButtonField按钮标题的静态文本。 每个按钮共享相同的标题。

可以使用 属性将 绑定到ButtonField数据源中的字段，而不是使用 TextDataTextField 属性在 对象中ButtonField显示静态文本。 然后，字段的值将显示为按钮的标题。

注意

DataTextField如果 同时设置了 和 Text 属性，则 DataTextField 属性优先。

此属性的值存储在视图状态中。

设置此属性的值后，可以使用设计器工具自动保存到资源文件。 有关详细信息，请参阅 LocalizableAttribute 和 全球化和本地化。
