BookmarkNode(String) Constructor

Initializes a new instance of the BookmarkNode class with the specified text.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v18.2.Core.dll

Declaration

C#

public BookmarkNode(
    string text
)

VB.NET

Public Sub New(
    text As String
)

Parameters

Name	Type	Description
text	String	A String specifying the bookmark’s text which will be shown in the document map. This value is assigned to the BookmarkNode.Text 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.
