水晶报表asp.net的webform下基本用法实例


            本文实例讲述了水晶报表asp.net的webform下基本用法。分享给大家供大家参考。

具体实现方法如下：

复制代码 代码如下: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.

希望本文所述对大家的asp.net程序设计有所帮助。
