The PdfViewerBookmarkExtensions.FindBookmark method allows you to find a bookmark that meets the specified criteria. This method can be useful if you need to find a bookmark in a document with a complex bookmark tree.

C#
VB.NET

csharp

using DevExpress.Pdf;

private void PdfViewer_DocumentLoaded(object sender, RoutedEventArgs e) {
    var bookmark = pdfViewer.Bookmarks.FindBookmark(x => x.Title == "4 Notation");
    if (bookmark != null) {
        pdfViewer.GoToBookmark(bookmark);
    }

}

Imports DevExpress.Pdf

Private Sub PdfViewer_DocumentLoaded(ByVal sender As Object, ByVal e As RoutedEventArgs)
    Dim bookmark = pdfViewer.Bookmarks.FindBookmark(Function(x) x.Title = "4 Notation")
    If bookmark IsNot Nothing Then
        pdfViewer.GoToBookmark(bookmark)
    End If
End Sub
