CrystalReportViewer中未显示数据

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，

Hi Experts,

I have created .xsd file and data is showing in the preview.I took all the fields in .rpt file and passing two parameters. When I run my below code Reportviewer showing only Parameter values. How can I get data?

Please help me to this helpless!

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();

Thanks,
