Create PDF from form data and save it

I am using editable pdf files (created by Nitro PDF Software) in my application. These pdf files have a lot of editable fields (like textboxes) and one button (like submit).

Whenever a user opens that pdf file, enters the text, and clicks the submit button they get redirected to an aspx page.

How do I get all the static and dynamic values that are posted to this page, and create another pdf file with the entered data? And how do I save the created pdf file?

Download itextSharp dll file,use namespace

using iTextSharp.text;
using iTextSharp.text.pdf;
using System.IO;
using iTextSharp.text.pdf.draw;

Document document = new Document(PageSize.A4,43,43, 43, 43);

To generate PDF, use following code:

NameSpace:

     Using System.IO;
     Using.iTextSharp.text;
     Using.iTextSharp.text.pdf;

On button click:

     private void button1_Click(object sender, EventArgs e)
    {
        Document doc = new Document(iTextSharp.text.PageSize.LETTER, 10, 10, 42, 35);
        PdfWriter writer = PdfWriter.GetInstance(doc, new FileStream(@"C:\Test.pdf", FileMode.Create));
        doc.Open();
        Paragraph paragraph = new Paragraph("Hi, \n This is xxx from yyy \n This is my pdf file");
        doc.Add(paragraph);
        doc.Close();
    }

From Wikipedia, PDF Interactive elements there are two possibilities for integrating data and PDFs (there are also links to the specifications):

  • AcroForms (also known as Acrobat forms), introduced in the PDF 1.2 format specification and included in all later PDF specifications.
  • Adobe XML Forms Architecture (XFA) forms, introduced in the PDF 1.5 format specification. The XFA specification is not included in the PDF specification, it is only referenced as an optional feature. Adobe XFA Forms are not compatible with AcroForms.

For compatibility issues I would go for AcroForms. In that case I would use XFDF, because it is XML and therefore easier to parse. I never used Nitro, but when you build a PDF form you usually provide a "Save" button and choose at action for this button "Send/Post form to server" with the data format XML which is just XFDF.

This works only when the PDF is viewed in the browser. So the typical use case is: have an empty PDF template on the server, before returning the PDF to the user mix your data into the PDF, the user enters data in the form (PDF is opened in the browser via a plugin or natively in Chrome), then the user presses the save buttons which posts a xml on the server. The next time the user asks for his PDF, you took the recent data and mix it again with the template.

So only two questions are open:

See the complete process here: http://itextpdf.com/book/chapter.php?id=9 . This example updates the PDF with the form dynamically at run time. Since iText is used there is no difference between Java and C#.

Be aware that previous versions of iText (Java up to 2.1.7 and C# up to 4.1.6) were distributed under the Mozilla Public License or the LGPL, while current versions are distributed under the Affero General Public License. Thats explains why the older versions are still used.

How do I get all the static and dynamic values that are posted to this page?

You can retreive them as you retrieve any other value from an html control, for example:

string MyVal = Request.Form["FieldName"];

and create another pdf file with the entered data?

Here you can use a PDF library of your choice ( iText.Net, Nitro PDF, Amyuni PDF Creator.Net ), load your PDF form, set the values to each field, flatten your file if needed, and save. The code for this part depends on the library being used, but they are usally well documented so you should be able to find sample code easily.
