               // string constr = ConfigurationManager.ConnectionStrings["conString"].ConnectionString;
                using (SqlConnection conn = new SqlConnection(SQLDAL.ConnectionString))
                {
                    using (SqlCommand cmd = new SqlCommand("CheckUserAvailability", conn))
                    {
                        cmd.CommandType = CommandType.StoredProcedure;
                        cmd.Parameters.AddWithValue("@UserName", username.Trim());
                        conn.Open();
                        status = Convert.ToBoolean(cmd.ExecuteScalar());
                        conn.Close();
