Do you have an identity column? If so, you can simply get the last row by selecting MAX(FieldName).

int i=dt.rows.count;
lbllogin.Content=dt.Rows[i-1]["login"].ToString();
lbllogout.Content = dt.Rows[i-1]["logout"].ToString();

EXCEPTION :

The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect.

Solution 2

select top(1)  *   from logindetails where [lusername]='" + loginusername + "'"  order by ID desc

N.B.where ID is your PK. Select last record as top 1 with descending order

            conn.Open();
            cmdd.ExecuteNonQuery();
            OleDbDataAdapter da = new OleDbDataAdapter(cmdd);
            da.Fill(dt);
            da.Fill(ds);
            int i;
            
                for ( i = 0; i <= dt.Rows.Count-2;i++ )
                {
                    lbllogin.Content = dt.Rows[i]["login"].ToString();
                    lbllogout.Content = dt.Rows[i]["logout"].ToString();
