本文實(shí)例講述了水晶報(bào)表asp.net的webform下基本用法。。

具體實(shí)現(xiàn)方法如下：

代碼如下: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;
}

使用方法.先建了一個(gè)數(shù)據(jù)集做為數(shù)據(jù)源,作為水晶報(bào)表的數(shù)據(jù)架構(gòu).

代碼里面調(diào)用一個(gè)存儲(chǔ)過(guò)程,返回?fù)碛卸鄰埍淼腄ataSet.

希望本文所述對(duì)大家的asp.net程序設(shè)計(jì)有所幫助。
