============
my method which i was design but it assign last value of sql query to all records in crystal report
----------------------------------------
  public void Sum_spay()
    {
        //// -------feetype
        ////        [1] senior ='S'
        ////        [2] multy ='M'

    ////----------------------------------------------------------------

     ParameterFields pfields = new ParameterFields();
         ParameterField pField = new ParameterField();
         ParameterDiscreteValue disVal = new ParameterDiscreteValue();
         ParameterRangeValue rVal = new ParameterRangeValue();
         sql = "SELECT  COUNT(srno)  FROM License WHERE animaltype = 'D' AND feetype = 'S'   

GROUP BY MONTH(pay_date)";
         cmd = new SqlCommand(sql, con);
         pField.ParameterFieldName = "mul";

         try
         {
             con.Open();
             dr = cmd.ExecuteReader();
             while (dr.Read())
             {
                 disVal.Value = dr[0];
                 pField.CurrentValues.Add(disVal);
                 pfields.Add(pField);
                 dc.SetParameterValue("mul", dr[0]);
                 // Response.Write("<br/>" + dr[0]);
             }
          
             CrystalReportViewer1.ParameterFieldInfo = pfields;
         }
         catch (Exception ex)
         {
             Response.Write(ex.Message);
         }
         finally
         {
             con.Close();
         }

    }
