水晶报表asp.netwebform下的基本使用

protected void Page_Init(object sender, EventArgs e)
{
     ConfigureCrystalReport();
 }
protected void Page_Unload(object sender, EventArgs e)
 {
         if (rptDocument == null)
            return;
           rptDocument.Close();
           rptDocument.Dispose();
  }

  private void ConfigureCrystalReport()
        {
            string temp = BusinessObject.Util.Decrypt(Request.QueryString["toid"]);
            TourOrderId = Util.ConvertTo<int>(temp, 0);

            if (ViewState["reportdoc"] == null)
            {
                string report_path = "";
                report_path = Server.MapPath("~/Report/TourNote.rpt");

                DataSet ds = BusinessObject.TourOrders.GetTourNoteDsRpt(TourOrderId);
                if (ViewState["reportdata"] == null)
                {
                    ViewState["reportdata"] = ds;
                }
                else
                {
                    ds = (DataSet)ViewState["reportdata"];
                }
                rptDocument = new ReportDocument();
                rptDocument.Load(report_path);
                rptDocument.SetDataSource(ds);
                rptDocument.PrintOptions.PaperSize = CrystalDecisions.Shared.PaperSize.DefaultPaperSize;
                ViewState["reportdoc"] = rptDocument;
            }
            else
            {
                rptDocument = (ReportDocument)ViewState["reportdoc"];
            }
          
            this.CrystalReportViewer1.ReportSource = rptDocument;
            this.CrystalReportViewer1.HasToggleGroupTreeButton = false;
            this.CrystalReportViewer1.DisplayGroupTree = false;
             
        }
 

使用方法.先建了一个数据集做为数据源,作为水晶报表的数据架构.

代码里面调用一个存储过程,返回拥有多张表的DataSet.
