Easiest way?
Use an ORDER BY clause on your SQL:

using (SqlCommand sqlcomm = new SqlCommand("SELECT * FROM remaining WHERE username=@username ORDER BY MySortColumn DESC", sqlconn))

But ... tw things.
1) Don't use SELECT * FROM - always name the columns you want to retrieve in the order you want to retrieve them. That way your code or display doesn't get messed up by a future change to the DB, and you don't waste memory or bandwidth fetching data you aren't going to use.
2) Why would you have more than one user with a same username? Normally, the username uniquely identifies a user and having two with the same name complicates matters...
