内容较长时，itextsharp不会创建新页面

Question

I try from 3 day to find way to make one pdf document, and I will appreciate any help.

I have few form fields which access and fill with no problem. Below of this fields I want to place dynamically created table. This table can be long enough to be on more than one page. And here is my problem. I can`t add this table on the same page with form fiels just below them. I find example which merge pdf files. And now I have this scenario.

1. Make one pdf with filled form fields
2. Make pdf with pdfTable which always be with only one page, but content is longer
3. Make pdf which is merge from first two. In first page is filled form fields and in second page is my pdfTable.

I just want to have form fields and table which starts from first page and continue on some next pages.

I post my code which is a little mess but ...

Your code is indeed a mess. I'll copy/paste it but please understand that I'm not a C# developer. I only know Java and I know iText inside-out (I'm its original developer).

string pdfTemplate = Server.MapPath("~/PDF/") + "invoiceTest.pdf";
string newFile = Server.MapPath("~/PDF/") + "invoice" + 1 + ".pdf";

using (FileStream ms = new FileStream(Server.MapPath("~/PDF/") + "invoice" + 1 + ".pdf", FileMode.Create))
using (FileStream formFile = new FileStream(Server.MapPath("~/PDF/") + "invoiceTest.pdf", FileMode.Open))
{
    PdfReader reader = new PdfReader(formFile);
    // YOU DON'T NEED A DOCUMENT OBJECT HERE!
    // READ THE DOCUMENTATION!!!
    PdfStamper outStamper = new PdfStamper(reader, ms);
    AcroFields fields = outStamper.AcroFields;
    BaseFont bfComic = BaseFont.CreateFont(Server.MapPath("~/PDF/") + "trebuc.ttf", BaseFont.IDENTITY_H, BaseFont.EMBEDDED);
    // UPDATE THE FORM FIELDS
    fields.SetFieldProperty("txtContragentName", "textfont", bfComic, null);
    fields.SetField("txtContragentName", "Фрея");
    fields.SetFieldProperty("txtContragentCode", "textfont", bfComic, null);
    fields.SetField("txtContragentCode", "DGB34TT");
    fields.SetFieldProperty("txtDateCreated", "textfont", bfComic, null);
    fields.SetField("txtDateCreated", "03.06.2013");
    outStamper.Close();
}

using (FileStream ms = new FileStream(Server.MapPath("~/PDF/") + "invoice" + 2 + ".pdf", FileMode.Create))
using (FileStream formFile = new FileStream(Server.MapPath("~/PDF/") + "invoice" + 1 + ".pdf", FileMode.Open))
{
    PdfReader reader = new PdfReader(formFile);
    // I'm adding extra parameters to change the margins so that they match what you had when you defined your ColumnText object
    using (Document document = new Document(reader.GetPageSizeWithRotation(1), 40, 40, 20, 20))
    {
        PdfWriter writer = PdfWriter.GetInstance(document, ms);
        document.Open();

The major mistake you made in the first part of your code, is introducing Document . There's no need for that. Please read chapter 6 of my book and take a look at the C# examples .

The major mistake you made in the second part is using ColumnText meaning you want to take control over the layout, but not knowing how to deal with that control. If you use ColumnText , you need to ask the column if all content was consumed. If not, you need to create a new page yourself. This is all explained in chapter 3 of my book.

The third part looks OK (as far as I understand C#).

I wrote my books so that people can save time by writing correct code from the start. I didn't write my books so that I have to copy/paste them on StackOverflow ;-)
