BookmarkNode Class

Represents a bookmark shown in the report’s document map.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v20.2.Core.dll

NuGet Packages: DevExpress.Printing.Core, DevExpress.WindowsDesktop.Printing.Core

Declaration

C#

public class BookmarkNode :
    StorableObjectBase,
    IBookmarkNode,
    IXtraPartlyDeserializable,
    IXtraSupportShouldSerializeCollectionItem,
    IXtraSupportDeserializeCollectionItem

VB.NET

Public Class BookmarkNode
    Inherits StorableObjectBase
    Implements IBookmarkNode,
               IXtraPartlyDeserializable,
               IXtraSupportShouldSerializeCollectionItem,
               IXtraSupportDeserializeCollectionItem

Remarks

Note that all the options of a bookmark can be set only when it’s created via the BookmarkNode object’s constructor. After a bookmark has been created, it can be added to the collection of bookmarks by calling the collection’s Add method. Use the BookmarkDuplicateSuppress property to remove duplicate bookmarks.

Note

BookmarkDuplicateSuppress removes only the bookmarks that are duplicated consecutively in the same group section.

Populate the BookmarkNodes collection with your bookmark nodes manually to remove duplicates throughout the report document.

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.
