Hi

sorry for my bad english ...

I have a few days working with version 2011.2 reports, these reports are generated with data I get from a webservice. for this I have a method that returns a DataTable via an IEnumerable generated the report (is rendered on the server side).
the code I use to generate the report is as follows:
  and the error I get is:
"Can not Establish Connection with report server" and the error in detail is:

"Infragistics.Controls.Reports.ReportServerException: Cannot establish a connection with the report server. ---> System.ServiceModel.ProtocolException: Content Type application/soap+msbin1 was not supported by service http://localhost:1517/ReportService1.svc.  The client and service bindings may be mismatched. ---> System.Net.WebException: The remote server returned an error: (415) Unsupported Media Type.

the IEnumerable I use to generate the report is as follows :

        public IEnumerable<Reporte2> getReporte2()
        {
            DataTable ds_resultado = new DataTable();
            string Fdesde = "08/02/2012";
            string Fhasta = "10/16/2012";
            ds_resultado = ws_foxpro.VerBitacora(Fdesde, Fhasta);
            //VerBitacora(Fdesde, Fhasta);
            List<Reporte2> rep = new List<Reporte2>();
            foreach (DataRow row in ds_resultado.Rows)
            {
                rep.Add(new Reporte2()
                {
                    supervisor = row["SUPER"].ToString(),
                    cod_cajero = row["CAJERO"].ToString(),
                    tipo_mov = row["TIP_MOV"].ToString(),
                    fecha = DateTime.Parse(row["FECHA"].ToString()),
                    nombre = row["desc"].ToString(),
                    hora = row["HORA"].ToString(),
                    mtoefeso = double.Parse(row["MTO_EFE"].ToString()),
                    desde = Fdesde,
                    hasta = Fhasta,
                    numReg = ds_resultado.Rows.Count,
                    fechaact = DateTime.Parse(row["fechaact"].ToString())

                });

            }
            return rep;
        }

Any Idea
