HTML

<div>
    <div id="dvGrid" runat="server">
        <asp:GridView ID="GridView1" HeaderStyle-BackColor="#3AC0F2" HeaderStyle-ForeColor="White"
            runat="server" AutoGenerateColumns="false">
            <Columns>
                <asp:BoundField DataField="Id" HeaderText="Id" ItemStyle-Width="30" />
                <asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
                <asp:BoundField DataField="Country" HeaderText="Country" ItemStyle-Width="150" />
            </Columns>
        </asp:GridView>
    </div>
    <div>
        Welcome to AspSnippets.
    </div>
    <table id="tbl1" runat="server">
        <tr>
            <td>
                Sale No :
                <asp:Label Text="1" runat="server" />
            </td>
        </tr>
        <tr>
            <td>
                Date:
                <asp:Label Text="23/09/2015" runat="server" />
            </td>
        </tr>
    </table>
    <br />
    <asp:Button Text="Print" runat="server" OnClick="Print" />
</div>
