Show/Hide AcroFields in iTextSharp

I have the following code:

PdfStamper pst = null;
        try
        {
            PdfReader reader = new PdfReader(GetTemplateBytes());
            pst = new PdfStamper(reader, Response.OutputStream);
            var acroFields = pst.AcroFields;

            pst.FormFlattening = true;
            pst.FreeTextFlattening = true;
            pst.SetFullCompression();

            SetFieldsInternal(acroFields);
            pst.Close();
        }

protected override void SetFieldsInternal(iTextSharp.text.pdf.AcroFields acroFields)
{
    acroFields.SetFieldProperty("txtForOffer", "setflags", PdfAnnotation.FLAGS_PRINT, null);
}

How do I show / hide the acrofields in the SetFieldsInternal function ?

The point is that the user may want to download 2 versions of the PDF, one with some text showing, one without text showing.

The template PDF is generated using OpenOffice. I just fill in the acrofields.

You can set an AcroField as readonly like this:

form.setFieldProperty("companyFld", "setfflags", PdfFormField.FF_READ_ONLY, null);

It is "setfflags" BTW not "setflags"

EDIT: MY BAD!!! You asked to make a field visible or not. You would use the "setflags" argument in this case and you can pass any of the PdfAnnotation FLAGS_ constants to adjust visibility.
