how to Add Input Text Field to Pdf (AcroForm) with PDFSharp

Question

it's should be simple but i couldn't find the answer anywhere in google or the source documentation.

someone have asked the same question 4 years ago, but still no one answered!

if it's not possible. can someone please confirm, so that i can find another pdf generator library that can do that. because it's very important in my case to be able to generate pdf with input capability

thanks!

Methinks it should work, but I cannot provide sample code (now). – Practise

please do when you have the time, i'm running out of option for opensource pdf generator library for c#. so i really hopes pdfSharp can do this – Dismantle

Answer 2

We will go through the step by step

1. First you need to create object of PdfReader
   • PdfReader pdfReader = new PdfReader(templatePath); here "templatePath" is the template(sample file) where you write your all data
2. Then create source file where all data is rendered(write)
   • System.IO.Directory.CreateDirectory(Server.MapPath(DocPath)); "DocPath" is the path where output file is save

3. Then Initialize PdfStamper and AcroFields object :

   PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(Server.MapPath(newFile), FileMode.Create));
   AcroFields pdfFormFields = pdfStamper.AcroFields;
   

4. Then set Field in PDF :

       pdfFormFields.SetField("this text should field name in PDF(template PDF)", "Actual value you want to write");
   

5. Dispose all objects

       pdfStamper.FormFlattening = true;
       pdfStamper.Close();
       pdfReader.Close();

Good that the code is working, but it does not answer the question. – Practise

are you sure its for pdfSharp? because i cant find pdfStamper in the library – Dismantle

The answer is not for PDFsharp, that's why it does not answer the question. – Practise

@IlikedtheoldStackOverflow any knowledge of whether it is possible to be done? – Ambit
