How can I add dynamically a textBox value using ItextSharp?

Hi I'm using a ITextSharp to create a PDF. This is my code:

private void FillForm()
{
    _path = HttpContext.Current.Server.MapPath("~/") + "\\PDF";
    string formFile = _path + "\\Test.pdf";
    string newFile = _path + "\\Test2.pdf";

    var reader = new PdfReader(formFile);
    using (var stamper = new PdfStamper(reader, new FileStream(newFile, FileMode.Create)))
    {
        AcroFields fields = stamper.AcroFields;

        var conn = new SqlConnection(DataManager.ConnectionString);
        conn.Open();

        var command = new SqlCommand("SQLCommand"), conn);
        var dt = new DataTable();
        var adapter = new SqlDataAdapter(command);

        adapter.Fill(dt);
        int rowIndex = 1;
        for (int i=0; i < dt.Rows.Count; i++)
        {
            var name = (string)dt.Rows[i]["Parameter"];
            fields.SetField("txt_" + rowIndex, name);
            rowIndex++;
        }

        stamper.FormFlattening = false;
        stamper.Close();
    }
}

I have a problem when I'm trying to fill the userName into textboxes. I have a list of names that I get it from the SQL query and I want to display it in different textboxes. Only the first textBox display its value. For the others I must click on textBox to view the value inside.

Does anyone have any idea how I can fix it?

One line is missing in your code:

fields.GenerateAppearances = true;

You need to add this line right after:

AcroFields fields = stamper.AcroFields;

Why is this happening? Your template is somewhat wrong (maybe it was created using OpenOffice): it says that the software used to fill out the form shouldn't generate the appearances of the fields. As a result the value of the field is added (this is proven by the fact that the text appears when you click it), but the appearance is missing (hence the blank fields).
