Simple TOC with itextsharp

Question

I have a website where I am displaying pdf with itextsharp in telerik radwindow. I am succeeded with displaying pdf on telerik radwindow popup. Now, I have page name and their order and need rearrange to display TOC like below with itextsharp

enter image description here

What you tried so far? Also what exactly is your question? And what do you use to display stuff? Is this on a website, inside a WinForms application, or is it WPF or are you trying to write to a text document... ? — MindSwipe, Mar 27 '19 at 10:02
Same question as https://stackoverflow.com/questions/55372460/text-alignment-issue-with-string-padding-when-generating-pdf — Amedee Van Gasse, Mar 27 '19 at 10:06
This is not a valid question. Showing a picture of something and saying "I want this", is not a question. I recommend reading [ask] and [mcve] in order to get the basic of asking on StackOverflow. — xdtTransform, Mar 27 '19 at 10:10
@AmedeeVanGasse yes it is same question. But here I am asking with itexsharp. and in another question I am trying to do it with padding(padright/padleft) of c#. I am appreciate team if they help me either one way. And if it is not a valid question then don't worry we have lots of resources where anyone can understood this. — Bunty Choudhary, Mar 27 '19 at 10:36

You can do this by creating a chunk separator (cf. this answer) with a tabPosition (to make the page numbers left aligned as you show in your image).

using (FileStream output = new FileStream(@"simpleToc.pdf", FileMode.Create, FileAccess.Write))
using (Document document = new Document(PageSize.A4))
{
    PdfWriter writer = PdfWriter.GetInstance(document, output);
    document.Open();

    Chunk leader = new Chunk(new DottedLineSeparator(), 400);

    Paragraph p = new Paragraph("Terms and Conditions");
    p.Add(leader);
    p.Add("4");
    document.Add(p);

    p = new Paragraph("Dental");
    p.Add(leader);
    p.Add("6");
    document.Add(p);

    p = new Paragraph("Vision");
    p.Add(leader);
    p.Add("7");
    document.Add(p);

    p = new Paragraph("Neighborhood Pharmacy");
    p.Add(leader);
    p.Add("8");
    document.Add(p);

    p = new Paragraph("Teladoc");
    p.Add(leader);
    p.Add("9");
    document.Add(p);

    p = new Paragraph("Retail Health Clinics");
    p.Add(leader);
    p.Add("11");
    document.Add(p);

    p = new Paragraph("Counseling Services");
    p.Add(leader);
    p.Add("12");
    document.Add(p);

    p = new Paragraph("Medical Bill Saver\u2122");
    p.Add(leader);
    p.Add("13");
    document.Add(p);

    p = new Paragraph("Vitamins");
    p.Add(leader);
    p.Add("14");
    document.Add(p);
}

The result looks like this

As you called the library "iTextSharp" and only used the [iText] tag, I assume you are using iText 5.x, not 7.x. The code above has been tested using the current 5.5.14-SNAPSHOT development version.

The Chunk constructor used above is marked Obsolete:

/**
* Creates a tab Chunk.
* Note that separator chunks can't be used in combination with tab chunks!
* @param   separator   the drawInterface to use to draw the tab.
* @param   tabPosition an X coordinate that will be used as start position for the next Chunk.
* @since   2.1.2
*/
[Obsolete]
public Chunk(IDrawInterface separator, float tabPosition) : this(separator, tabPosition, false)

But as the old iText 5.x version as a whole is in maintenance mode, there is no need to fear that it will be dropped from the assembly during further development.
