on selected row in Gridview show more specific data in different Gridview

Question

I do have a database containing 10 columns, and in the first Gridview I m showing only couple of records with limited data. And what I want to do is selecting that record (gridview1) and show all data in a different Gridview below (Gridview2). The gridview2 will pop up after selecting row on gridview1.

Anyone knows how to make it right? I appreciate any help!
Thanks!
