    <p>I have a class that build the content for my table of contents and that works, fine and dandy. Here's the code:</p> <pre><code>public void Build(string center,IDictionary&lt;string,iTextSharp.text.Image&gt; images) { iTextSharp.text.Image image = null; XPathDocument rapportTekst = new XPathDocument(Application.StartupPath + @"..\..\..\RapportTemplates\RapportTekst.xml"); XPathNavigator nav = rapportTekst.CreateNavigator(); XPathNodeIterator iter; iter = nav.Select("//dokument/brevhoved"); iter.MoveNext(); var logo = iTextSharp.text.Image.GetInstance(iter.Current.GetAttribute("url", "")); iter = nav.Select("//dokument/gem_som"); iter.MoveNext(); string outputPath = iter.Current.GetAttribute("url", "")+center+".pdf"; iter = nav.Select("//dokument/titel"); iter.MoveNext(); this.titel = center; Document document = new Document(PageSize.A4, 30, 30, 100, 30); var outputStream = new FileStream(outputPath, FileMode.Create); var pdfWriter = PdfWriter.GetInstance(document, outputStream); pdfWriter.SetLinearPageMode(); var pageEventHandler = new PageEventHandler(); pageEventHandler.ImageHeader = logo; pdfWriter.PageEvent = pageEventHandler; DateTime timeOfReport = DateTime.Now.AddMonths(-1); pageWidth = document.PageSize.Width - (document.LeftMargin + document.RightMargin); pageHight = document.PageSize.Height - (document.TopMargin + document.BottomMargin); document.Open(); var title = new Paragraph(titel, titleFont); title.Alignment = Element.ALIGN_CENTER; document.Add(title); List&lt;TableOfContentsEntry&gt; _contentsTable = new List&lt;TableOfContentsEntry&gt;(); nav.MoveToRoot(); iter = nav.Select("//dokument/indhold/*"); Chapter chapter = null; int chapterCount = 1; while (iter.MoveNext()) { _contentsTable.Add(new TableOfContentsEntry("Test", pdfWriter.CurrentPageNumber.ToString())); XPathNodeIterator innerIter = iter.Current.SelectChildren(XPathNodeType.All); chapter = new Chapter("test", chapterCount); while(innerIter.MoveNext()) { if (innerIter.Current.Name.ToString().ToLower().Equals("billede")) { image = images[innerIter.Current.GetAttribute("navn", "")]; image.Alignment = Image.ALIGN_CENTER; image.ScaleToFit(pageWidth, pageHight); chapter.Add(image); } if (innerIter.Current.Name.ToString().ToLower().Equals("sektion")) { string line = ""; var afsnit = new Paragraph(); line += (innerIter.Current.GetAttribute("id", "") + " "); innerIter.Current.MoveToFirstChild(); line += innerIter.Current.Value; afsnit.Add(line); innerIter.Current.MoveToNext(); afsnit.Add(innerIter.Current.Value); chapter.Add(afsnit); } } chapterCount++; document.Add(chapter); } document = CreateTableOfContents(document, pdfWriter, _contentsTable); document.Close(); } </code></pre> <p>I'm then calling the method <code>CreateTableOfContents()</code>, and as such it is doing what it is supposed to do. Here's the code for the method:</p> <pre><code>public Document CreateTableOfContents(Document _doc, PdfWriter _pdfWriter, List&lt;TableOfContentsEntry&gt; _contentsTable) { _doc.NewPage(); _doc.Add(new Paragraph("Table of Contents", FontFactory.GetFont("Arial", 18, Font.BOLD))); _doc.Add(new Chunk(Environment.NewLine)); PdfPTable _pdfContentsTable = new PdfPTable(2); foreach (TableOfContentsEntry content in _contentsTable) { PdfPCell nameCell = new PdfPCell(_pdfContentsTable); nameCell.Border = Rectangle.NO_BORDER; nameCell.Padding = 6f; nameCell.Phrase = new Phrase(content.Title); _pdfContentsTable.AddCell(nameCell); PdfPCell pageCell = new PdfPCell(_pdfContentsTable); pageCell.Border = Rectangle.NO_BORDER; pageCell.Padding = 6f; pageCell.Phrase = new Phrase(content.Page); _pdfContentsTable.AddCell(pageCell); } _doc.Add(_pdfContentsTable); _doc.Add(new Chunk(Environment.NewLine)); /** Reorder pages so that TOC will will be the second page in the doc * right after the title page**/ int toc = _pdfWriter.PageNumber - 1; int total = _pdfWriter.ReorderPages(null); int[] order = new int[total]; for (int i = 0; i &lt; total; i++) { if (i == 0) { order[i] = 1; } else if (i == 1) { order[i] = toc; } else { order[i] = i; } } _pdfWriter.ReorderPages(order); return _doc; } </code></pre> <p>The problem is however. I want to insert a page break before the table of contents, for the sake of reordering the pages, so that the table of contents is the first page, naturally. But the output of the pdf-file is not right.</p> <p>Here's a picture of what it looks like: <img src="https://i.stack.imgur.com/PUARt.jpg" alt="Picture"></p> <p>It seems like the <code>_doc.NewPage()</code> in the <code>CreateTableOfContents()</code> method does not execute correctly. Meaning that the image and the table of contents is still on the same page when the method starts the reordering of pages.</p> <p>EDIT: To clarify the above, the <code>_doc.NewPage()</code> gets executed, but the blank page is added after the picture and the table of contents.</p> <p>I've read a couple of places that this could be because one is trying to insert a new page after an already blank page. But this is not the case.</p> <p>I'll just link to the pdf files aswell, to better illustrate the problem.</p> <p>The pdf with table of contents: <a href="http://freepdfhosting.com/326fe4967c.pdf" rel="nofollow noreferrer">with table of contents</a></p> <p>The pdf without table of contents: <a href="http://freepdfhosting.com/e4d8601349.pdf" rel="nofollow noreferrer">without table of contents</a></p> <p>Thank you in advance for your help :)</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
