//To retrieve the values from a DataKeyNames collection,
//you can use "Key Names" or "index"
//Get the values with key names
string productId = GridView1.DataKeys[e.RowIndex].Values["ProductID"].ToString();
string orderId = GridView1.DataKeys[e.RowIndex].Values["OrderID"].ToString();
//Or
//Get the values with index
string productId = GridView1.DataKeys[e.RowIndex].Values[0].ToString();
string orderId = GridView1.DataKeys[e.RowIndex].Values[1].ToString();
위와 같이 사용하면 된다. 이걸 몰라서 삽질..ㅡㅡ;;
