how to arrange values in descending order in asp.net?

hi,

check this:

 str = "select Sum(FEELERS) as FEELERS ,sum(INTUITORS) as INTUITORS,sum(THINKERS) as THINKERS,sum(SENSORS) as SENSORS from GivenAns where UserID =1";
        dt = ObjConn.GetDataTable(str);
        if (dt != null && dt.Rows.Count > 0)
        {
            dt.DefaultView.Sort = "FEELERS desc";// sort applied to 1st column
            dt = dt.DefaultView.ToTable();         
        }

it's not working i am using datatable

try like this

ds.Tables[0].DefaultView.Sort = "columnname desc";
ds.Tables[0] = ds.Tables[0].DefaultView.ToTable();
