PDF - Text not showing when filling form

Question

I'm facing a problem when filling a PDF form using iTextSharp, I'm using the following code to fill the PDF form:

PdfReader pdfReader = new PdfReader(Properties.Resources.ConfirmationFees);
PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(folderPath + "\\" +fileName, FileMode.Create));

AcroFields pdfFFields = pdfStamper.AcroFields;

pdfFFields.SetFieldProperty("Text1", "textsize", 10.0f, null);

pdfFFields.SetField("Text1", serialNumber.ToString("D6") + "№");

pdfStamper.FormFlattening = false;

// close the pdf
pdfStamper.Close();

When I open the PDF, I have to select the textField and go to Properties, select border color or fill color, and click on "No Color". or just simply add a character to the textField.

I've tried to set the border and background color of the textField to null, but without luck.

So, how can I solve this problem without doing the mentioned way?

If you are using Unicode text, see this answer: http://stackoverflow.com/a/10274659/298573 — VahidN, May 24 '14 at 18:45

How did you create your form? If with Open/Libre Office, then the forms are a little bit crappy. You may need to add this line:

pdfFFields.setGenerateAppearances(true);

In your specific C# snippet, that would be:

pdfFFields.GenerateAppearances = true;

If this doesn't solve your problem, you need to tell us which version of iTextSharp you're using. If it's older than 5.5.1, please upgrade.

I'm using iTextSharp V. 5.4.1.0, I've check the `pdfFFields.GenerateAppearances = true;` and it does not solve my problem. Also, I'm not flatten the PDF. I've created the PDF using inDesign, created a textfield in it and using the file as a template for my desktop application. – Scar May 24 '14 at 14:24
Share the PDF please, also tell us which font you use. – Bruno Lowagie May 24 '14 at 21:02
Solved my issue... A template created with Acrobat Pro worked fine but then I switched to using an alternative editor. The template saved by the non-Adobe editor necessitated the this additional line of code. – Tahbaza Mar 19 '18 at 19:52
