Cannot load new pdf in RadPdfViewer after using UnloadDocument

I am working on a Windows Forms Application that load and print PDF document then unload that document  and load new one, but when i call unloadDocument() no new document was loaded :

                   RadPdfViewer rViewer = new RadPdfViewer();
                    rViewer.DocumentLoaded += RViewer_DocumentLoaded;
                    rViewer.LoadDocument(Filepath);
                    rViewer.LoadElementTree();
                    Application.DoEvents();
                    rViewer.PdfViewerElement.StopWaiting();
                    if (rViewer.IsLoaded)
                    { rViewer.UnloadDocument(); }

after unloadde the document i cannot load new PDF doccument?

Hello, luai, 

Following the provided information, I was unable to reproduce the issue you are facing. Please refer to the attached gif file illustrating the behavior on my end with the latest version. I used PrimoPDF to simulate the printer.

I have attached my sample project. Could you please specify the exact steps how to reproduce the problem? Feel free to modify it in a way to reproduce the experienced issue and get back to me with it so I can investigate the precise case. Thank you in advance. 

I am looking forward to your reply.
