The grid can be exported to Excel, PDF, etc. and also you can print it - please check our demos for more info.
As for PDF viewer control, we are planning to include such a tool in our suite of controls. However, due to the many pressing tasks in our to-do list, we cannot bind to a specific timeline for now, but by rough estimations, it should be available with the Q1 2012 release.
