How to add a hidden text field?

I'd like to create a text field with iTextSharp that is not visible.

Here's code I'm using to create a text field:

TextField field = new TextField(writer, new Rectangle(x, y - h, x + w, y), name);
field.BackgroundColor = new BaseColor(bgcolor[0], bgcolor[1], bgcolor[2]);
field.BorderColor = new BaseColor(
    bordercolor[0], bordercolor[1], bordercolor[2]);
field.BorderWidth = border;
field.BorderStyle = PdfBorderDictionary.STYLE_SOLID;
field.Text = text;
writer.AddAnnotation(field.GetTextField());

In Java, the TextField class has a method named setVisibility() inherited from its parent, the BaseField class. Possible values are:

BaseField.VISIBLE,
BaseField.HIDDEN,
BaseField.VISIBLE_BUT_DOES_NOT_PRINT, and
BaseField.HIDDEN_BUT_PRINTABLE.

As you're using iTextSharp, you should look for the Visibility property.

field.Visibility = BaseField.HIDDEN;
