Export GridView with Logo image to PDF in ASP.Net

Instead use the table with Repeater control. Add your Logo in Table. Refer this:

<table border="0" cellpadding="0" cellspacing="0">
            <tr>
                <td>
                    Image
                </td>
            </tr>
            <asp:Repeater ID="rpt_Demo" runat="server">
                <ItemTemplate>
                    <tr>
                        <td>
                            <asp:Label runat="server" Text="your text" />
                        </td>
                    </tr>
                </ItemTemplate>
            </asp:Repeater>
        </table>

Add this in Panel and Export that in Pdf.

Thank You.
