本文實(shí)例講述了水晶報(bào)表asp.net的webform下基本用法。分享給大家供大家參考。

具體實(shí)現(xiàn)方法如下：

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;
}
