DataGridColumnStyle dcStyle = new DataGridTextBoxColumn();
dcStyle......
....
dcStyle.HeaderText = "姓名";
dtStyle.GridColumnStyles.Add(dcStyle);dcStyle = new DataGridTextBoxColumn();
....
dcStyle.HeaderText = "地址"
.........................Add(dcStyle);// 假定 dtStyle 设定 DataGrid的 DataGridTableStyle

}
我是在查询字符串里添加的：SELECT UserName as 姓名,Pwd as 密码 From dbo.User ORDER BY UserName
简单点用sql语句，select c1 as 列1 from table,这样fill dataset就有列名了
在TableStyles里面设
你也可以用程序动态的加上去，
建议看看MSDN
