Hello Hanna,
DynamicPDF Viewer control itself does not have a tabbed or split interface that would allow you to open multiple PDFs at the same time. However, you can place multiple DynamicPDF Viewer controls onto a Winform with the help of SplitContainer or TabControl form controls available in System.Windows.Forms namespace.
Thanks,
