I need to cancel edition by user when opening the PDF document. I tried
FormFlattening=true but when i do it, all AcroFields in my document appear
empty. What am i doing wrong??? Thanks even for reading this.
I have the folowing code:
...
PlantillaImpresion oPlantilla =
(PlantillaImpresion)Session["Plantilla"];
string pdfTemplate = @"c:\Temp\PDF\" + oPlantilla.Nombre +
".pdf";
string newFile = @"c:\Temp\PDF\terminado" +
oPlantilla.Nombre + ".pdf";
PdfReader pdfReader = new PdfReader(pdfTemplate);
pdfStamper = new PdfStamper(pdfReader, new
FileStream(newFile, FileMode.Create));
AcroFields pdfFormFields = pdfStamper.AcroFields;
string oImpCampo = string.Empty;
foreach (ImpresionContrato oImp in oSetImpresiones)
{
InsertarTexto(oImp.PlantillaCampo.Nombre, oImp.Valor,
pdfStamper);
string
oAuxiliar=pdfFormFields.GetField(oImp.PlantillaCampo.Nombre);
}
pdfStamper.FormFlattening = true;
DataTable oTemp = new DataTable();
System.Collections.Hashtable info = new
System.Collections.Hashtable();
info["Title"] = oPlantilla.Nombre;
info["Author"] = UserSession.Usuario.Apellido+"
"+UserSession.Usuario.Nombre;
info["Creator"] = "123";
pdfStamper.Close();
pdfStamper.Writer.CloseStream = true;
System.Diagnostics.Process oProcess = new
System.Diagnostics.Process();
oProcess.StartInfo.WorkingDirectory = @"C:\Temp\PDF";
oProcess.StartInfo.FileName = "terminado" +
oPlantilla.Nombre + ".pdf";
oProcess.Start();
oProcess.Close();
...
where
private void InsertarTexto(string oCampo, string oValor, PdfStamper
pdfStamper)
{
//string oNom =
pdfStamper.AcroFields.Xfa.DatasetsNode.ChildNodes[0].ChildNodes[0].ChildNodes[2].Name;
bool oBandera = false;
int oCont = 0;
while (oBandera.Equals(false))
{
if
(pdfStamper.AcroFields.Xfa.DatasetsNode.ChildNodes[0].ChildNodes[0].ChildNodes[oCont].Name.Equals(oCampo))
{
pdfStamper.AcroFields.Xfa.DatasetsNode.ChildNodes[0].ChildNodes[0].ChildNodes[oCont].InnerText
= oValor;
pdfStamper.AcroFields.Xfa.Changed = true;
BaseFont helvetica = BaseFont.CreateFont("Helvetica",
BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
pdfStamper.AcroFields.AddSubstitutionFont(helvetica);
oBandera = true;
}
else
{
oCont++;
}
}
}
