推荐答案

此错误表示您的VS工作正常.
选定的不是"System.Data.DataRowView"的属性.
复选框的已选中"属性应该为true或false.

this error means that your VS is working fine.
Selected is not a property of ''System.Data.DataRowView''.
"Checked" property of checkbox should either be true or false.

根据您提供的链接，已选中"必须是以下属性(复选框将绑定到该属性)数据源.在实施之前，请先完整阅读(并理解)本文.还请提及您要实现的目标.

As per the link you provided, "Selected" must be a property (to which the check-boxes will be bound) in the DataSource. Please read (and understand) the article completely before implementing. Also please mention what are you trying to achieve.
