Get the export value of a checkbox using iTextSharp

Question

I\'m working on dynamically filling in the fields on a pdf document using ITextSharp. I\'d like to be able to determine the \"export value\" of the checkbox is from the cod

Answer 1

This was the final method I used to get it working based on the others:

    public string GetCheckBoxExportValue(AcroFields fields, string cbFieldName)
    {
        AcroFields.Item item = fields.GetFieldItem(cbFieldName);
        if (item.values.Count > 0)
        {
            PdfDictionary valueDict = item.values[0] as PdfDictionary;
            PdfDictionary appDict = valueDict.GetAsDict(PdfName.AP);

            if (appDict != null)
            {
                PdfDictionary normalApp = appDict.GetAsDict(PdfName.N);

                foreach (PdfName curKey in normalApp.Keys)
                {
                    if (!PdfName.OFF.Equals(curKey))
                    {
                        // string will have a leading '/' character
                        return curKey.ToString(); 
                    }
                }
            }

            PdfName curVal = valueDict.GetAsName(PdfName.AS);
            if (curVal != null)
            {
                return curVal.ToString();
            }

        }

        return null;
    }
