Declaration

C#

public class PdfBookmark :
    IPdfBookmarkParent

VB.NET

Public Class PdfBookmark
    Implements IPdfBookmarkParent

Remarks

An instance of the PdfBookmark class is accessible via the PdfDocument.Bookmarks property.

You can change a bookmark’s attribute (e.g., rename a bookmark using the PdfBookmark.Title property, change the bookmark’s font style using the PdfBookmark.IsBold, PdfBookmark.IsItalic properties, and specify the bookmark destination using the PdfBookmark.Destination property).

Important

The bookmark hierarchy must contain only distinct instances of the PdfBookmark class. The following code snippet shows this prohibited action.

C#

PdfBookmark bookmark = new PdfBookmark();
bookmark.Children.Add(bookmark);

VB.NET

Dim bookmark As PdfBookmark =  New PdfBookmark() 
bookmark.Children.Add(bookmark)

Example

This example shows how to create bookmarks in code.

To do this:

• Create a PdfBookmark object;
• Specify the bookmark title and destination using the PdfBookmark.Title and PdfBookmark.Destination properties. To create a destination, call one of the PdfDocumentProcessor.CreateDestination overloaded methods.
• Add the bookmark to the PdfBookmark collection, which is accessed from the PdfDocument.Bookmarks property.
