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.
