            ParameterValues crParameterValues = new ParameterValues();
            ParameterDiscreteValue crParameterDiscreteValue = new ParameterDiscreteValue();

            crParameterDiscreteValue.Value = txtNfrmNo.Text;
            crParameterFieldDefinitions = cryRpt.DataDefinition.ParameterFields;
            crParameterFieldDefinition = crParameterFieldDefinitions["FormNo"];
            crParameterValues = crParameterFieldDefinition.CurrentValues;

            crParameterValues.Clear();
            crParameterValues.Add(crParameterDiscreteValue);
            crParameterFieldDefinition.ApplyCurrentValues(crParameterValues);

                //Family Photo           

            CRVPage1.ReportSource = cryRpt;
            CRVPage1.RefreshReport();
          }
          catch (Exception ex)
          {

推荐答案

ReportDocument rptDoc = new ReportDocument();
   dsSample ds = new dsSample(); // .xsd file name
   DataTable dt = new DataTable();

   // Just set the name of data table
   dt.TableName = "Crystal Report Example";
   dt = getAllOrders(); //This function is located below this function
   ds.Tables[0].Merge(dt);

   // Your .rpt file path will be below
   rptDoc.Load(Server.MapPath("../Reports/SimpleReports.rpt"));

   //set dataset to the report viewer.
   rptDoc.SetDataSource(ds);
   CrystalReportViewer1.ReportSource = rptDoc;
