ASP.NET的问题DataBinding:“System.Data.DataRowView”不包含名为“E_mail”的属性

在aspx页面中
<asp:Label ID="pwdLabel" runat="server" Text='<%# Bind("pwd") %>'></asp:Label><br />
 E_mail:
 <asp:Label ID="E_mailLabel" runat="server" Text='<%# Bind("E_mail") %>'></asp:Label><br />
添加时间:
 <asp:Label ID="addedtimeLabel" runat="server" Text='<%# Bind("addedtime") %>'></asp:Label><br />
上面报错！！
这是aspx页面的全部代码！！

            <HeaderTemplate> --------------------编程问答-------------------- 数据源中看看有没有E_mail --------------------编程问答-------------------- 数据库中有 --------------------编程问答--------------------
你确定user表有E_mail字段的话，就把这句写成完整的形式看看
 SelectCommand="SELECT * FROM [user]"；
就是把要查询的字段也写出来


--------------------编程问答-------------------- 但是这是一个可以执行增加，编辑，删除的的语句啊，不会死一个完整的查询语句啊
--------------------编程问答-------------------- 这是对数据的一个编辑，删除，增加的SQL语句，不是要查询全部的东西
