DataSet1TableAdapters.dataProductTableAdapter dt = new DataSet1TableAdapters.dataProductTableAdapter();
                dt.Fill(ds.dataProduct);
                DataTable dt1 = new DataTable();
                dt1 = ds.dataProduct;

                ReportViewer1.Reset();
                ReportViewer1.LocalReport.DataSources.Clear();
ReportDataSource rds = new ReportDataSource("DataSet1", dt1); 
                ReportViewer1.LocalReport.DataSources.Add(rds);  //添加数据源
                ReportViewer1.ZoomMode = ZoomMode.Percent;
