ii have  added a dataset called st_DS and ,make a datatable with 6 cloumns

 

also i'v add a report 

then i added a web form with report viewer control

as 

<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
      <rsweb:ReportViewer ID="ReportViewer1" runat="server"></rsweb:ReportViewer>

 then there is a button wich must do all the work

this is the code behind

string xml_resp = objCmd.Parameters["p_out"].Value.ToString();
            XmlTextReader reader = new XmlTextReader(new System.IO.StringReader(xml_resp));
            st_DS stt = new st_DS();
            stt.ReadXml(new XmlTextReader(new System.IO.StringReader(xml_resp)));


            ReportViewer1.ProcessingMode = ProcessingMode.Local;
            ReportViewer1.LocalReport.ReportPath = Server.MapPath("st.rdlc");
            ReportViewer1.LocalReport.DataSources.Clear();
            ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("st_DS", stt.Tables["1"]));
//also tried//  ReportViewer1.LocalReport.DataSources.Add(new ReportDataSource("st_DS", stt.Tables["0"]));
            ReportViewer1.LocalReport.Refresh();
