Hello all,

I am currently using ItextSharp to create a PDF file. I am working on generating a header along with a table below. The table works without any problems but when the header runs it creates a duplicate of 4 headers. I have been experimenting and working on solving this problem but so far I have had no luck after multiple hours.

C#

  class PrintForAccess    {
        Document printAccess2CareDoc;
        const int LINES_PER_ACCESS2CARE_DOC = 5;
        int pageCount = 0;
        PdfWriter writer;
        public void PrintAccessPDF(IEnumerable<ride> records, DateTime ridedate, int driverid, bool groupByDriver, string username, Stream outputstream, int tenantid, bool splitByDriver = false)
        {
printAccess2CareDoc = new iTextSharp.text.Document(PageSize.LETTER.Rotate(), .2f, .2f, .2f, .2f);
            writer = PdfWriter.GetInstance(printAccess2CareDoc, outputstream);
            PdfAcroForm acroForm = writer.AcroForm;
     printAccess2CareDoc.Open();
            PdfPTable table = printAccess2CareInitTable(defaultFont);
            PdfPTable headTable = printHeadTableAccess2Care(headerFont);          
            int detailLine = 0;
            driver previousDriver = null;
            bool firstRec = true;
            foreach(ride record in records)
            {
                if(groupByDriver && record.driver != previousDriver || firstRec)
                {                    
                    previousDriver = record.driver;              
                    detailLine = 0;
                    printAccess2CareNewPage(ref table, ref headTable, defaultFont, headerFont, firstRec);

You're calling printAccess2CareHeader for every record. Therefore, it's hardly surprising that you're getting a header for every record.

Change your code to only call that method when you want to display a header.

I am only getting 4 Headers not one for every record. I had one of the method calls commented out but then i was getting 0 headers

Here is the answer to my question
I finally solved it!!

C#

foreach(ride record in records)
           {
               if(groupByDriver && record.driver != previousDriver || firstRec)
               {
                   if(!firstRec)
                   {
                       printAccessFivelengths(ref table, defaultFont, detailLine, headTable, headerFont);
                   }
                   previousDriver = record.driver;

                   if (record.driver != null && (driverid != 0 || groupByDriver))
                   {
                       //pageHeaderWithDriver.Add(new Phrase(titlec1 + record.driver.person.fullname, headerFont));
                       c4r2head = new PdfPCell(new Phrase(record.driver.person.fullname, headerFont));
                       headerTable.AddCell(c4r2head);
                   }
                   detailLine = 0;
                   printAccessHeader(headTable, record, ridedate, username);
                   printAccessNewPage(ref table, ref headTable, defaultFont, headerFont, firstRec);

                   table = printAccessInitTable(defaultFont);
                   headTable = printAccessHeaderInit(headerFont);
               }

               printAccessDetail(table, defaultFont, writer, record, ridedate);

               if((++detailLine) == LINES_PER_ACCESS_DOC)
               {
                   detailLine = 0;
                   //print new page
                   printAccessHeader(headTable, record, ridedate, username);
                   printAccessNewPage(ref table, ref headTable, defaultFont, headerFont, false);
               }
               firstRec = false;
           }
