Gridview VS database

Question

Hi...! I use VS2008 & creating a ASP.NET web site. My question is... I have a gridview & I want to get limited columns(3 or 4) from a data table(suppose it's a 6 column table implemented in SQL)to the gridview. once I get the data columns into my grid view I want to select one row(record) and need to get the full description of selected record(6 columns). I dont know what control I should use to get the full description (gridview/listview/listbox/panel...) and these two things should be happpend in the same page. And also I want to know what is the command that I can use to access any element in a such control(gridview/listbox/listview/dropdownlist......) I need someone's help to do this......!!!! thanks....
