Answer 1

private void reportViewer1_Drillthrough(object sender, Microsoft.Reporting.WinForms.DrillthroughEventArgs e)
        {            Microsoft.Reporting.WinForms.LocalReport report = e.Report as Microsoft.Reporting.WinForms.LocalReport;            string procedurelistid = report.GetParameters()["ProcedureId"].Values[0].Trim();
           
            string sequenceId = report.GetParameters()["Sequenceid"].Values[0].Trim();            
            DataRow[] rows = this.employeeDt.Select("procedurelistid= '" + procedurelistid + "' and sequenceId=" + sequenceId);
            this.prDs.EmployeeInfo.Clear();
            foreach(DataRow row in rows)
            {
                this.prDs.EmployeeInfo.ImportRow(row);
            }
            report.DataSources.Clear();
            report.DataSources.Add(new Microsoft.Reporting.WinForms.ReportDataSource("ProductControlReportDataSet_EmployeeInfo", this.prDs.EmployeeInfo));        } 表employeeInfo中有数据,但是最后出来的报表显示不出数据!?!?!
