Post subject:  PdfAcroForm and multiline problem
Hi
Im trying to fill a acrobat document form field with a multiline text and hav no success.

Im using:
Code:
PdfTextField _f = (PdfTextField)(form.Fields[name]);
_f.MultiLine = true;         
_f.Text = value;

And
Code:
        PdfSharp.Pdf.AcroForms.PdfAcroField fieldLocation = form.Fields["address"];
        PdfSharp.Pdf.AcroForms.PdfTextField txtFieldLocation;
        if ((txtFieldLocation = fieldLocation as PdfSharp.Pdf.AcroForms.PdfTextField) != null)
        {
            txtFieldLocation.MultiLine = true;
            var sb = new System.Text.StringBuilder();
            sb.AppendLine("John Doe123");
            sb.AppendLine("Text from new line1");
            sb.AppendLine("Text from new line2");
            sb.AppendLine("Text from new line3");
            txtFieldLocation.Text = sb.ToString();
        }


And have tried all kind of linebreaks, stringbuilder with AddLine, html br \r \n \r\n
The source document has the field marked as multiline but i can only get the text on one line.

Any ideas?

Hi

And code:
Code:
PdfTextField _f = (PdfTextField)(form.Fields["olle"]);
_f.MultiLine = true;
_f.Value = new PdfString("firstline\nnextline");

and
Code:
PdfSharp.Pdf.AcroForms.PdfAcroField fieldLocation = form.Fields["olle"];
        PdfSharp.Pdf.AcroForms.PdfTextField txtFieldLocation;
        if ((txtFieldLocation = fieldLocation as PdfSharp.Pdf.AcroForms.PdfTextField) != null)
        {
            var sb = new System.Text.StringBuilder();
            sb.AppendLine("Text from new line1");
            sb.AppendLine("Text from new line2");
            txtFieldLocation.MultiLine = true;
            txtFieldLocation.Value = new PdfString(sb.ToString(), PdfStringEncoding.Unicode);
        }

You have a document, I don't.
Please use the Issue Submission Template if you think there is a bug.

Ok, sorry about that.

I now got it to work, sort of...
The problem is firefox, i was testing in firefox built in pdf-reader and it seeams like it cant handle forms in pdf properly.
Running in Edge or chrome shows the line breaks.
