GridView實現數據編輯和刪除(一)

前臺的html代碼：

<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="用戶號" ReadOnly="True" />
            <asp:BoundField DataField="Emp_name" HeaderText="登陸名" />
            <asp:BoundField DataField="Password" HeaderText="密碼" />
            <asp:BoundField DataField="name" HeaderText="姓名" />
            <asp:BoundField DataField="Email" HeaderText="Email" />
            <asp:BoundField DataField="Jb" HeaderText="用戶類型" />
            <asp:BoundField DataField="Tell" HeaderText="聯繫電話" />
            
            <asp:CommandField ShowEditButton="True" />            //編輯
            <asp:CommandField ShowDeleteButton="True" />          //刪除
        </Columns>
        
    </asp:GridView>

後臺代碼：

            if (em.Del_EmploginInfo(Emp_id) == 1)
            {
                Emplogin_Bind();
