iTextSharp Export ASP.Net WebPage with Image to PDF Error - Could not find a part of the path

Hi Richa,

If you want the page to work with images you need to convert the Relative Urls to Absolute ones.

Example : ~/Images/1.jpg must be changed to http://localhost/Images/1.jpg

Check this example. Now please take its reference and correct your code.

HTML

<div>
    <img runat="server" id="img" /><br />
</div>
<div style="font-family: Arial">
    This is a test page</div>
<div>
    <table border="1" width="100">
        <tr>
            <td>Name</td>
            <td>Age</td>
        </tr>
        <tr>
            <td>John</td>
            <td>11</td>
        </tr>
        <tr>
            <td>Sam</td>
            <td>13</td>
        </tr>
        <tr>    
            <td>Tony</td>
            <td>12</td>
        </tr>
    </table>
</div>
<div>
    <asp:Button ID="btnExport" runat="server" Text="Export" OnClick="btnExport_Click" /></div>
