public partial class Form1 : RibbonForm
{
    Cursor currentCursor = null;

    //This property checks whether the cursor is located within the document's borders
    bool CursorIsOverPage { get { return pdfViewer.IsDocumentOpened && pdfViewer.GetDocumentPosition(pdfViewer.PointToClient(MousePosition), false) != null; } }

    public Form1()
    {
        InitializeComponent();
        pdfViewer.CursorMode = PdfCursorMode.Custom;
        pdfViewer.MouseMove += PdfViewer_MouseMove;
        currentCursor = pdfViewer.Cursor;

    }


    private void PdfViewer_MouseMove(object sender, MouseEventArgs e)
    {
        //Show the No cursor when it hovers over the document
        pdfViewer.Cursor = currentCursor != null && CursorIsOverPage ? Cursors.No : currentCursor;
    }
}
