前台的html代码：

<asp:GridView ID="gv_Emplogin" runat="server" AutoGenerateColumns="False" onrowdeleting="gv_Emplogin_RowDeleting" onrowupdating="gv_Emplogin_RowUpdating" onrowediting="gv_Emplogin_RowEditing" onrowcancelingedit="gv_Emplogin_RowCancelingEdit"><Columns><asp:BoundField DataField="Emp_id" HeaderText="用户号" ReadOnly="True" /><asp:BoundField DataField="Emp_name" HeaderText="登录名" /><asp:BoundField DataField="Password" HeaderText="密码" /><asp:BoundField DataField="name" HeaderText="姓名" /><asp:BoundField DataField="Email" HeaderText="Email" /><asp:BoundField DataField="Jb" HeaderText="用户类型" /><asp:BoundField DataField="Tell" HeaderText="联系电话" /><asp:CommandField ShowEditButton="True" />            //编辑<asp:CommandField ShowDeleteButton="True" />          //删除</Columns></asp:GridView>
