CrystalReportViewer中未显示数据 [英] Data is not showing in CrystalReportViewer

问题描述

嗨专家，



我创建了.xsd文件，数据显示在预览中。我获取了.rpt文件中的所有字段并传递了两个参数。当我运行我的下面的代码Reportviewer时只显示参数值。我怎样才能获得数据？



请帮助我这个无奈！



ReportDocument reportCaseByAgency = new ReportDocument （）;

reportCaseByAgency.Load（Server.MapPath（@〜/ Reports / RPT_CaseByAgency.rpt））;

reportCaseByAgency.FileName = Server.MapPath（@ 〜/ Reports / RPT_CaseByAgency.rpt）;

reportCaseByAgency.SetParameterValue（@ QTR，num2）;

reportCaseByAgency.SetParameterValue（@ Year，year）;

ReportViewer1.ReportSource = reportCaseByAgency;

//reportCaseByAgency.ReadRecords（）;

//ReportViewer1.RefreshReport（）;

//ReportViewer1.DataBind（）;



谢谢，

推荐答案

您缺少要附加的代码您的数据。



您应该拥有某种类型的数据源，可能是包含报告中所需信息的DataSet。然后像这样添加：

You are missing code to attach your data.

You should have a Data Source of some type, likely a DataSet that contains the information you want in the report. Then add it like this:

reportCaseByAgency.SetDataSource(myDataSet);

$ b设置ReportView1.ReportSource之前$ b

。

before setting the ReportView1.ReportSource.
