Looking for datagridview tutorial

I am looking for a tutorial or example of datagridview usage. Here is what I am trying to do. I have a form with 2 datagridviews on it. DGV1 is bound to the employee table in database 1. DGV2 is bound to the time card punches in database 2. Both work separately. What I need though, if that when I select a record from DGV1, I need to fill DGV2 with their time card punches. I am hoping to do it without writing any code. I can do the code, but I am thinking that the proper .NET way has to do with binding somehow. maybe I am wrong on that.
