错误：A field or property with the name 'XXX' was not found on the selected data source 解决

 

有时候， 我绑定一个datasource到grid,会出现以下错误问题：

 

A field or property with the name 'To' was not found on the selected data source

 

 

 

 

原因：

datasource的item对象中，没有property

比如：

 

 public class Email
 {
        public string From = "";
        public string To = "";
        public string Subject = "";
        public string Body = "";

 }

这是不可以的，

 

 

 

解决方案：

 

应该改成这样！

 

 public class Email
    {
        private string _from = "";
        private string _to = "";
        private string _subject = "";
        private string _body = "";

        public string To
        {
            get { return _to; }
            set { _to = value; }
        }

        public string From
        {
            get { return _from; }
            set { _from = value; }
        }

        public string Subject
        {
            get { return _subject; }
            set { _subject = value; }
        }

        public string Body
        {
            get { return _body; }
            set { _body = value; }
        }
    }
