Of course it doesn't draw - it has no appearance (/AP). Acrobat/Reader is correct - your PDF is wrong.
I am GUESSING that for some reason iTextSharp isn't generating an appearance for the read_only field...Check the code.

We are generating an Acroform with some fields ... all kinds of fields. See attached example of one sample generated PDF. The problem exists only in fields marked as "read only" and further the problem only seems to occur when displayed in Adobe Reader (not other PDF viewers). When displayed with Adobe Reader, these fields do not appear as visible but the fields are there as confirmed if submitting the form information to our server or examining the PDF. The same code is used for regular textbox (works fine), password (works fine). If default values exist, they are shown in the PDF. But when setting a Field Flag of "PdfFormField.FF_READ_ONLY", the default value is not visible in the form. We think the code works because: A) it works for all other cases B) totally works in other viewers (The same PDF when viewed in FoxIt shows the field exactly as expected with the field contents as read only.) A sample PDF is attached showing this behavior. There is a field in the table marked as FF_READ_ONLY after the cell labeled "Simple Reader Only Textbox". The field contains the text "Cannot change contents" and the field exists and has this value (confirmed by submitting to our server -- will work with XFDF submit only from Adobe Reader, not an FDF submit from other products). The question is: a) Is this a "your code is all wrong" problem (likely :) b) Is this an Adobe Reader bug? (we tried and can create read-only fields with Acrobat) c) Is this an iTextSharp bug? Kevin Brown Code sample: If the following case statement is called with "f_readonly" as "true", then the PDF contains the field but no default value is visible (in Adobe Reader only). If it is called with f_readonly as "false" or "f_type" as password, the field works perfectly in Adobe Reader. case "password": case "textbox": tp = cb.CreateAppearance(urx - llx, ury - lly); da = (PdfAppearance)tp.Duplicate; field = PdfFormField.CreateTextField(writer, false, false, 0); field.SetWidget(new iTextSharp.text.Rectangle(llx, lly, urx, ury), PdfAnnotation.HIGHLIGHT_INVERT); setBordersAndColors(field, f_borderstyle, f_bordersize, f_bordercolor, f_backcolor); field.FieldName = f_name; da.SetFontAndSize(setFont(formfontfam, formfontstyle, formfontweight), Convert.ToSingle(formfontsize)); if (formfontcolor.StartsWith("#")) da.SetColorFill(new iTextSharp.text.Color(HexToColor(formfontcolor))); else da.SetColorFill(new iTextSharp.text.Color(System.Drawing.Color.FromName(formfontcolor))); field.DefaultAppearanceString = da; if (f_default.Length > 0) field.ValueAsString = f_default; if (f_type == "password") field.SetFieldFlags(PdfFormField.FF_PASSWORD); if (f_readonly == "true") field.SetFieldFlags(PdfFormField.FF_READ_ONLY); field.SetPage(); acroform.AddFormField(field); break; ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php
