MouseEvents not working in PDFNet SDK latest version

Hello, I need some help. I am usinng PDFtron pdfnet sdk for one of my projects. I have a requirement where I need to implement all of the MouseEvents, like Mouse over, Mouse click, mouse double click, etc.,
When I use an old version of the PDFNet sdk, version 4.something, I have no issues, but when I use the newer version, these events do not work at all..
I have tried everything. But to disappointments. Can you help me with this problem?

Are you using PDFViewCtrl for C++, or are you using WinForms .Net?
