BookmarkNodeCollection Class

Represents a document map which contains a collection of all the bookmarks in a document.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v23.2.Core.dll

NuGet Package: DevExpress.Printing.Core

Declaration

C#

public class BookmarkNodeCollection :
    Collection<BookmarkNode>,
    IBookmarkNodeCollection,
    IList,
    ICollection,
    IEnumerable

VB.NET

Public Class BookmarkNodeCollection
    Inherits Collection(Of BookmarkNode)
    Implements IBookmarkNodeCollection,
               IList,
               ICollection,
               IEnumerable

Remarks

Each bookmark in the BookmarkNodeCollection collection is represented by an BookmarkNode object and can be added to the collection by calling the collection’s Add method. Note that if a brick to which the bookmark refers is split across two or more pages, then the bookmark will reference the part which is printed on the page returned via the BookmarkNode.Page property.

Example

This example illustrates how to make Print Preview display a Document Map listing all bookmarks assigned to a Document‘s elements.

The following code adds five bricks to the Detail section of a document and then assigns bookmarks to each brick.

Note that the Document Map button is automatically enabled in Print Preview when a displayed document has any bookmarks.
