SqlCommand query = new SqlCommand("SELECT lastname, firstname, middlename  FROM tblStudent WHERE fldID='" + txtSearch.Text + "'", amicassaCon);
          SqlDataReader dr = query.ExecuteReader();
          while (dr.Read())
          {
              string a = dr[1].ToString();
            string b = dr[2].ToString();
             string c= dr[3].ToString();
              txtName.Text = a + ',' + b + ' ' + c;
          dr.Close();
