  • Add a GridView control in design page of your website under <BODY> tag

         <AlternatingRowStyle BackColor="White" />
        <asp:BoundField DataField="EMP_NAME"  HeaderText="Name" />
        <asp:BoundField DataField="DEPT"  HeaderText="Department" />
        <asp:BoundField DataField="SALARY"  HeaderText="Salary" />  
         <EditRowStyle BackColor="#2461BF" />
         <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
         <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
         <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
