            SqlCommand com = new SqlCommand(str, con);
            SqlDataAdapter sqlda = new SqlDataAdapter(com);
            DataSet ds = new DataSet();
            sqlda.Fill(ds, "Project");
            con.Close();

            ReportDocument r1 = new ReportDocument();
            //r1.Load("Full Path of Your Report\Employee.rpt");
            //string path = Server.MapPath("Reports/Service Bill.rpt");
