Ich bin neu bei iTextSharp.
Wie kann ich einen Datensatz pro Seite drucken?
Kann mir jemand einen Beispielcode zur Verfügung stellen, der mir zeigt, wie ich mein Ziel erreichen kann?

diese Lösung Versuchen:

using (var output = new MemoryStream()) 
      { 
       using (var document = new iTextSharp.text.Document(iTextSharp.text.PageSize.A4, 40, 40, 30, 90)) 
       { 
        using (var writer = PdfWriter.GetInstance(document, output)) 
        { 
         Phrase phrase = null; 
         PdfPCell cell = null; 
         PdfPTable table = null; 
         try 
         { 
          document.Open(); 
          document.PageCount = 1; 
          writer.PageEvent = new Footer(data); 

          foreach (var item in data) 
          { 
           table = new PdfPTable(1); 
           table.SpacingBefore = 20; 
           table.WidthPercentage = PageSize.A4.Width; 
           float[] ProfessionalServices = new float[1]; 
           ProfessionalServices[0] = (float)(1 * PageSize.A4.Width); 
           table.SetWidthPercentage(ProfessionalServices, PageSize.A4); 

           phrase = new Phrase("Record :" + item); 
           cell = new PdfPCell(phrase); 
           cell.Border = 0; 
           cell.Padding = 2; 
           cell.Colspan = 3; 
           cell.HorizontalAlignment = Element.ALIGN_RIGHT; 
           table.AddCell(cell); 

           table.WriteSelectedRows(0, -1, document.Left, document.Top - (100 + 20), writer.DirectContent); 
           document.Add(table); 

           document.ResetPageCount(); 
           document.NewPage(); 
          } 
          document.Close(); 
         } 
         catch (Exception ex) 
         { 

         } 

         if (!Directory.Exists(current.Server.MapPath("~/bill-pdf/"))) 
          Directory.CreateDirectory(current.Server.MapPath("~/bill-pdf/")); 
         string pdfFilePath = current.Server.MapPath("~/bill-pdf/" + guid + ".pdf"); 
         File.WriteAllBytes(pdfFilePath, output.ToArray()); 
         if (File.Exists(filePath)) 
          File.Delete(filePath); 
        } 
       } 
      } 

Footer Code Methode:

#region Footer Class 

    public partial class Footer : PdfPageEventHelper 
    { 
     #region Constructor 
     public Footer() 
     { 

     } 
     #endregion 

     #region OnStartPage 
     public override void OnStartPage(PdfWriter writer, Document document) 
     { 
      if (document.PageNumber > 1) 
      { 
       string footerMessage = "Page " + document.PageNumber; 
       Paragraph footer = new Paragraph(footerMessage, FontFactory.GetFont(FontFactory.HELVETICA, 9)); 
       footer.Alignment = Element.ALIGN_RIGHT; 
       PdfPTable footerTbl = new PdfPTable(numColumns: 1); 
       footerTbl.WidthPercentage = 100; 
       footerTbl.TotalWidth = PageSize.A4.Width; 

       PdfPCell cell = new PdfPCell(new Phrase(footer)); 
       cell.Border = 0; 
       cell.HorizontalAlignment = Element.ALIGN_RIGHT; 
       footerTbl.AddCell(cell); 
       footerTbl.WriteSelectedRows(0, -1, document.RightMargin - 80, document.Top + 30, writer.DirectContent); 
      } 
     } 
     #endregion 

     #region OnEndPage 
     public override void OnEndPage(PdfWriter writer, Document doc) 
     { 

      string footerMessage = "Footer Text"; 


       Paragraph footer = new Paragraph(footerMessage, FontFactory.GetFont(FontFactory.HELVETICA, 9)); 
       footer.Alignment = Element.ALIGN_CENTER; 
       PdfPTable footerTbl = new PdfPTable(numColumns: 1); 
       footerTbl.TotalWidth = PageSize.A4.Width; 

       PdfPCell cell = new PdfPCell(new Phrase(footer)); 
       cell.Border = 0; 
       cell.HorizontalAlignment = Element.ALIGN_CENTER; 
       footerTbl.AddCell(cell); 
       //footerTbl.WriteSelectedRows(0, 10, 50, 55, writer.DirectContent); 
       footerTbl.WriteSelectedRows(0, -1, 0, 55, writer.DirectContent); 

     } 
     #endregion 

    } 

    #endregion 

Try-Code können Sie Header gesetzt und eigene Inhalte für Header Fußzeile OnStartPage() ändern und Fußzeile ändern OnEndPage()
