How to create nested bookmarks by Essential PDF

[Jason Li]

I am trying to add bookmarks on different levels to pdf document.But no idea how to do it?

I want to add bookmarks like:

-Chapter 1
--Section 1
----Page 1
----Page 2
------Paragraph 3
----Page 3
-Chapter 2
-Index

Thanks.

Another question is what the difference between Essential PDF ASP.NET and Essential PDF Windows is? Can't I use Essential PDF in both web app and windows app?

Hi Jason,

Thanks for using Syncfusion products.

Please find below the answer for your queries

I. PDF Nested Bookmarks

Please go through the following steps to add nested bookmarks to a PDF document.

1. Create a PDF document object either by loading a PDF file.

PdfLoadedDocument docMain = new PdfLoadedDocument(filePath);

2. Set Bookmark panel visible and create root book mark.

//To have the Bookmark panel visible by default.
docMain.ViewerPreferences.PageMode = PdfPageMode.UseOutlines;

//To initiate the Root Bookmark, so that bookmarks can be added henceforth.
docMain.CreateBookmarkRoot();

3. Add book mark to the PDF document and assign to a PdfBookMark object.

//Assigning display name for the bookmark
PdfBookmark pdfBookMark = docMain.Bookmarks.Add("Top Book Mark");

4. Assign the page to be navigated when clicking this Book mark.

//Setting the target page to be displayed after clicking the bookmark link.
pdfBookMark.Destination = new PdfDestination(docMain.Pages[0]);

5. Add Level 2 Sub Book mark for the root book mark and its destination page.

PdfBookmark pageBookMark1 = pdfBookMark.Add("Page 1");

pdfBookMark[0].Destination = new PdfDestination(docMain.Pages[0]);

6. Add Level 3 Sub Book mark for the Level 2 Book mark and its destination pages.

pageBookMark1.Add("Quarter 1");

pageBookMark1[0].Destination = new PdfDestination(docMain.Pages[0], new PointF(10, 200));

pageBookMark1.Add("Quarter 2");

pageBookMark1[1].Destination = new PdfDestination(docMain.Pages[0], new PointF(10, 400));

pageBookMark1.Add("Quarter 3");

pageBookMark1[2].Destination = new PdfDestination(docMain.Pages[0], new PointF(10, 600));

NOTE: N number of hierarchy level Bookmarks can be set.
