                        alert(result.status + ' : ' + result.statusText);
                    }
                });

        [WebMethod]
        public static List<ProjectManPowerDetails> getData(string projectCode, string date)
        {
            string query = "select  pd.empCode, pd.amount from tbl_ManPowerProject_details pd inner join tbl_ManPowerProject_Master pm on pm.id = pd.project_Id where pm.projectCode = '"+projectCode+"' and pm.assignedDate = '"+date+"'";
            DataTable dt = SqlConn.SqlExce.fillDataTableRet(query);
            List<ProjectManPowerDetails> lst = new List<ProjectManPowerDetails>();
            foreach (DataRow dr in dt.Rows)
            {
                lst.Add(new ProjectManPowerDetails
                {
                    //Id = Convert.ToInt32(dr["Id"]),
                    empName = dr["empCode"].ToString(),
                    amount = Convert.ToDecimal(dr["amount"])                    
                });
            }
            return lst;
        }
