Contextfilter for DataGrid

Currently I’m working as a database and application developer for a big auditing company in Frankfurt, Germany. At desk my daily doing is based on SQL-Server and .Net-programming, and I admit that in my off-time things can stay the same. But before worrying about my social life let me tell you that I love doing sports with my friends, to travel with my wife, to read ficitional literature and that I desperately try to learn russian as third foreign language.
