Filling form of Editable Dynamic XFA PDF

I used itextSharp dll, add this dll in our reference and include in namespace

using iTextSharp;

using iTextSharp.text;

using iTextSharp.text.pdf;

·        From this PDF we can Generate XML

PdfReader reader = new PdfReader(Load_USPTO_PDF_Template_Path);

PdfStamper stamper = new PdfStamper(reader, new FileStream(Temp_PDF_Copy_Path, FileMode.CreateNew, FileAccess.ReadWrite));

AcroFields form = stamper.AcroFields;

XfaForm xfa = form.Xfa;

·        We can access the Xml to fill data using  XmlDocument method

XmlDocument xmldoc = new XmlDocument();

xmldoc.LoadXml(form.Xfa.DatasetsNode.FirstChild.OuterXml);

·        Now data filled XML can be saved in temporary path and can be imported to the PDF

….Our code to fill XML

xmldoc.Save(Temp_XML_Save_path);

·        Now we can fill the XML into PDF & Give to user

xfa.FillXfaForm(Temp_XML_Save_path);

stamper.Close();
