You mean you want to iterate over some data rows to create a table in your PDF?
Could you expand your question with a sample/mockup of the desired output?

here productbind(); is a function ..

Hi,

I think you can construct something with an iteration over the table rows while building your string. Something in the order of:

(warning pseudo code)

C#

...
sb.Append("");
// Just construct your layout, e.g. table and styling

// And continue to iterate over your data
foreach(var row in YourCollectionOfRows){
  // include any styling if you like 
  sb.Append($"Customer name: {row.CustomerName}");
  sb.Append($"Ticket number: {row.TicketNumber}");
}

// And finalize the layout (closing the table structure and stuff)
sb.Append("");
...

For one thing, that's completely unreadable. For another, you either have to use single quotes around the various html attribute values or escape the double quotes.

C#

sb.AppendLine  ("<table width='100%' cellspacing='0' cellpadding='2'>");
sb.AppendLine  ("    <tbody>");
sb.AppendLine  ("        <tr>");
sb.AppendLine  ("            <td colspan='4'></td>");
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr><td></td><td></td><td></td> <td></td></tr>");
sb.AppendLine  ("        <tr><td style='font-size:10px;' colspan='4'>TSW Packaging Solutions</td></tr>");
sb.AppendLine  ("        <tr><td style='font-size:10px;' colspan='4'>S No 8, Sagun Niwas Dange Chowk – Tathawade Road, Tathawade, Pune - 411033</td></tr>");
sb.AppendLine  ("        <tr>");
sb.AppendFormat("            <td style='font-size:10px;' colspan='2'> REF :- {0}</td>", lblticket.Text);.AppendLine();
sb.AppendFormat("            <td style='font-size:10px;' colspan='2'>Date :-  {0}</td>", System.DateTime.Today);.AppendLine();
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr>");
sb.AppendFormat("            <td style='font-size:10px;' colspan='4'> Kind Attn :- {0}</td>", lblcustomer.Text);.AppendLine();
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr>");
sb.AppendFormat("            <td style='font-size:10px;' colspan='4'> M/S. :- {0}</td>", lblcompany.Text).AppendLine();
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr>");
sb.AppendFormat("            <td style='font-size:10px;' colspan='4'> Subject :- {0}</td>", txtsubject.Text).AppendLine(); 
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr>");
sb.AppendFormat("            <td style='font-size:10px;' colspan='4'>  {0}</td>", txtbody.Text).AppendLine();  
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("        <tr>");
//SEE EDIT BELOW
//sb.AppendFormat("            <td style='font-size:10px;' colspan='4'>  {0}</td>", productbind()).AppendLine();
sb.AppendLine  ("        </tr>");
sb.AppendLine  ("    </tbody>");
sb.AppendLine  ("</table>");

I don't know what the productbind method does.

EDIT ===============================

Your responses are STILL too vague for precise help, but this should be what you're looking for. I can't possibly spoon feed you more than this because you're piece-mealing the info to us and frankly, I'm bored with the question. Be a programmer and nut it out from here.

C#

var product = productbind();
sb.AppendFormat("      <td style='font-size:10px;'>{0}</td>", product.field1).AppendLine();
sb.AppendFormat("      <td style='font-size:10px;'>{0}</td>", product.field2).AppendLine();
sb.AppendFormat("      <td style='font-size:10px;'>{0}</td>", product.field3).AppendLine();
sb.AppendFormat("      <td style='font-size:10px;'>{0}</td>", product.field4).AppendLine();
