    <p>first at all, here is my code:</p> <pre><code> string pdfTemplate = Application.StartupPath + "\\Templates\\Template Medico.pdf"; string newFile = Application.StartupPath + "\\Relatórios\\Relatório Médico_" + dataArquivo + ".pdf"; PdfReader pdfReader = new PdfReader(pdfTemplate); PdfStamper pdfStamper = new PdfStamper(pdfReader, new FileStream(newFile, FileMode.Create)); AcroFields pdfFormFields = pdfStamper.AcroFields; // Form Filling pdfFormFields.SetField("data", data); pdfFormFields.SetField("medico_nome", campo); pdfFormFields.SetField("numero_consultas", numeroConsultas); // Table Building int numColumns = ds.Tables[0].Columns.Count; PdfPTable datatable = new PdfPTable(numColumns); datatable.DefaultCell.Padding = 10; datatable.WidthPercentage = 100; datatable.DefaultCell.HorizontalAlignment = Element.ALIGN_LEFT; float[] columnWidths = { 80, 80, 80, 80, 80, 80, 80, 80, 80 }; datatable.SetWidths(columnWidths); float[] totalWidth = { 80, 80, 80, 80, 80, 80, 80, 80, 80 }; datatable.SetTotalWidth(totalWidth); // Table Header for (int k = 0; k &lt; ds.Tables[0].Columns.Count; k++) { Phrase collumname = new Phrase(ds.Tables[0].Columns[k].ColumnName, FontFactory.GetFont("Verdana", 9)); datatable.AddCell(collumname); } // Lines and Columns if (ds.Tables[0].Rows.Count &lt;= 9) // less than 9 rows = no problem, no new pages and table spliting needed { for (int i = 0; i &lt; ds.Tables[0].Rows.Count; i++) { for (int j = 0; j &lt; ds.Tables[0].Columns.Count; j++) { datatable.DefaultCell.BackgroundColor = iTextSharp.text.BaseColor.WHITE; datatable.DefaultCell.HorizontalAlignment = iTextSharp.text.Element.ALIGN_LEFT; Phrase phrase = new Phrase(ds.Tables[0].Rows[i][j].ToString(), FontFactory.GetFont("Verdana", 9)); datatable.AddCell(phrase); } } // Write down the table on page 2 PdfContentByte content = pdfStamper.GetUnderContent(2); datatable.WriteSelectedRows(0, -1, 70.0f, 495.0f, content); } else { int newPage = 3; int currentPage = 2; for (int i = 0; i &lt; ds.Tables[0].Rows.Count; i++) { for (int j = 0; j &lt; ds.Tables[0].Columns.Count; j++) { datatable.DefaultCell.BackgroundColor = iTextSharp.text.BaseColor.WHITE; datatable.DefaultCell.HorizontalAlignment = iTextSharp.text.Element.ALIGN_LEFT; Phrase phrase = new Phrase(ds.Tables[0].Rows[i][j].ToString(), FontFactory.GetFont("Verdana", 9)); datatable.AddCell(phrase); } if (i &gt; 0 &amp;&amp; i % 9 == 0) { //How do i print the table ONLY every 9 iterations? (9 iterations = 9 rows) PdfContentByte content = pdfStamper.GetUnderContent(currentPage); // Or how do i make a loop using the rowStart and rowEnd arguments of the // WriteSelectedRows function in order to write only a set of 9 rows for each page? datatable.WriteSelectedRows(0, -1, 70.0f, 495.0f, content); pdfStamper.InsertPage(newPage, pdfReader.GetPageSize(2)); newPage++; currentPage++; } } } </code></pre> <p>The code is well commented with the main issues i'm having at the moment, but the real bigger one, as described on the thread title is to somehow "split" or "control" the loop/iteration through the rows and columns to match the page, jump to the other page, and keep writing the table.</p> <p>Any help will be apreciated.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
