Answer 1

You are creating an A4 document in landscape format with this line:

Document pdfDoc = new Document(PageSize.A4.Rotate(), 10f, 10f, 100f, 0f);

If you want to create a document in envelope format, you shouldn't create an A4 page, instead you should do this:

Document pdfDoc = new Document(envelope, 10f, 10f, 100f, 0f);

In this line, envelope is an object of type Rectangle.

There is no such thing as the envelope size. There are different envelope sizes to choose from: http://www.paper-papers.com/envelope-size-chart.html

For instance, if you want to create a page with the size of a 6-1/4 Commercial Envelope, then you need to create a rectangle that measures 6 by 3.5 inch. The measurement system in PDF doesn't use inches, but user units. By default, 1 user unit = 1 point, and 1 inch = 72 points.

Hence you'd define the envelope variable like this:

Rectangle envelope = new Rectangle(432, 252);

Because:

6 inch x 72 points = 432 points (the width)
3.5 inch x 72 points = 252 points (the height)

If you want a different envelope type, you have to do the calculations of the dimensions of that envelope format.

I want to generate multiple pdf by using this code but it is generating only one PDF ... then going to catch block, Please give solution of this problem.

Response.ContentType = "application/pdf";
Response.AddHeader("content-disposition", "attachment;filename=" + begin + ".pdf");
Response.Cache.SetCacheability(HttpCacheability.NoCache);
StringWriter sw = new StringWriter();
HtmlTextWriter hw = new HtmlTextWriter(sw);
Panel1.RenderControl(hw);
StringReader sr = new StringReader(sw.ToString());
Document pdfDoc = new Document(PageSize.A4, 10f, 10f, 100f, 0f);
HTMLWorker htmlparser = new HTMLWorker(pdfDoc);
PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
pdfDoc.Open();
htmlparser.Parse(sr);
pdfDoc.Close();
Response.Write(pdfDoc);
Response.End();
