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。
