  • As explained *many, many, many* times before on Stack Overflow, in answer to *many, many, many* identical questions: `HTMLWorker` **is no longer supported.** Read the [intro of the HTML to PDF tutorial](https://developers.itextpdf.com/content/itext-7-converting-html-pdf-pdfhtml) to learn about the history of HTML to PDF conversion with iText(Sharp). – Bruno Lowagie Nov 15 '17 at 06:28
  • See the comments of [C# iTextSharp How to convert a piece of HTML into PDF](https://stackoverflow.com/questions/46827052), [Itextsharp HTML Table Conversion](https://stackoverflow.com/questions/46936960), [How to display chinese characters in PDF using ITextSharp in c#?](https://stackoverflow.com/questions/47075049), [C# iTextSharp How to convert a piece of HTML into PDF](https://stackoverflow.com/questions/46827052), and many other instances where we explained that `HTMLWorker` will cause nothing but frustration! **Stop using it! Upgrade to iText 7 + pdfHTML!** – Bruno Lowagie Nov 15 '17 at 06:35
  • please provide better option for export repeater data into PDF. if possible provide source code with reference . – Sunny Raval Nov 15 '17 at 07:03
  • Stack Overflow is not a forum where you can ask people to do your homework. I will vote to close your question because of your comment. Asking "provide source code" isn't appreciated here. – Bruno Lowagie Nov 15 '17 at 07:11
  • i just telling that provide better solution – Sunny Raval Nov 15 '17 at 08:32
  • I just told: try iText 7 + pdfHTML. Read about it in the [HTML to PDF tutorial](https://developers.itextpdf.com/content/itext-7-converting-html-pdf-pdfhtml). You mentioning `Repeater` is irrelevant. You are essentially converting HTML to PDF. So don't confuse people by asking for "better option for export repeater data." – Bruno Lowagie Nov 15 '17 at 10:49
