{
ReportDocument rpt = new ReportDocument();
rpt.Load(Server.MapPath("Report.rpt"));
ParameterFieldDefinitions crParameterFieldDefinitions;
ParameterFieldDefinition crParameterFieldDefinition;
ParameterValues crParameterValues = new ParameterValues();
ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();
crParameterDiscreteValue.Value = Session["OrderNo"];
crParameterFieldDefinitions = rpt.DataDefinition.ParameterFields;
crParameterFieldDefinition = crParameterFieldDefinitions["@OrderNo"];
crParameterValues = crParameterFieldDefinition.CurrentValues;
crParameterValues.Clear();
crParameterValues.Add(crParameterDiscreteValue);
crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);
CrystalReportViewer1.Visible = true;
CrystalReportViewer1.ReportSource = rpt;

this example is only for one parameter step 1: go to to Global.asax(add this by right clicking ur solution explorer and select add new item) . in this create a session called session[" OrderNo"] in ur session_start event . void Session_Start( object sender, EventArgs e) {Session[ "OrderNo" ] = "" ;} step 2 : go to ur first page add this code in ur button click event protected void Button1_Click( object sender, EventArgs e) { DropDownList1.SelectedValue= Session[ "OrderNo" ].ToString(); Response.Redirect( "Default2.aspx" ); // Default2.aspx is the second page whr u have ur crystal report } step 3 : add this code in ur page_load event of second page protected void Page_Load( object sender, EventArgs e) { ReportDocument rpt = new ReportDocument (); rpt.Load(Server.MapPath( "CrystalReport.rpt" )); ParameterFieldDefinitions crParameterFieldDefinitions; ParameterFieldDefinition crParameterFieldDefinition; ParameterValues crParameterValues = new ParameterValues (); ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue (); crParameterDiscreteValue.Value = Session[ "OrderNo" ]; crParameterFieldDefinitions = rpt.DataDefinition.ParameterFields; crParameterFieldDefinition = crParameterFieldDefinitions[ "@OrderNo" ]; crParameterValues = crParameterFieldDefinition.CurrentValues; crParameterValues.Clear(); crParameterValues.Add(crParameterDiscreteValue); crParameterFieldDefinition.ApplyCurrentValues(crParameterValues); CrystalReportViewer1.Visible = true ; CrystalReportViewer1.ReportSource = rpt; CrystalReportViewer1.DisplayGroupTree = false ; } this code is working fine for me.. try out once more n let me know..
