    var cropBox = pageInfo.CropBox;

    PdfPoint stickyNotePoint = new PdfPoint(cropBox.Right - 20, cropBox.Top - 20);

    var points = new[] { new PointF((float)stickyNotePoint.X, (float)stickyNotePoint.Y) };

    PdfDocumentPosition stickyNotePosition = new PdfDocumentPosition(1, new PdfPoint(points[0].X, points[0].Y));
    var stickyNoteColor = System.Windows.Media.Color.FromRgb(214, 222, 4);
    pdfViewer.AddStickyNote(stickyNotePosition, "Note", stickyNoteColor);
}

Private Sub pdfViewer_DocumentLoaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs)
  Dim pageInfo = pdfViewer.GetPageInfo(1)
