问题描述

RptSuperannuationReport RptSuperannuationReport = new RptSuperannuationReport（）;

RptSuperannuationReport.SetDataSource（PVDT）;

// ReportDocument myDataReport = new CrystalDecisions.CrystalReports.Engine.ReportDocument（）;

//myDataReport.Load(@\"C:\Layouts\Report.rpt）;







ReportDocument reportDocument = new ReportDocument（）;

ParameterField paramField = new ParameterField（）;

ParameterFields paramFields = new ParameterFields（） ;

ParameterDiscreteValue paramDiscreteValue = new ParameterDiscreteValue（）;

Crv_RptView.Refresh（）;

//设置输入参数1的实例 - FromDate

paramField.Name =FromDate;
//下面的变量可以设置为任何数据

//存在于SalseData表中，Department列

paramDiscreteValue.Value = FromDate;

paramField.CurrentValues.Add（paramDiscreteValue）;



paramFields.Add（paramField）;



paramField = new ParameterField（）;

paramField.Name =ToDate;

paramDiscreteValue = new ParameterDiscreteValue（）;

paramDiscreteValue.Value = ToDate;

paramField.CurrentValues.Add（paramDiscreteValue）;



//将paramField添加到paramFields

paramFields.Add（paramField）;



Crv_RptView.Pa rameterFieldInfo = paramFields;







Crv_RptView.ReportSource = RptSuperannuationReport;

//Below variable can be set to any data
//present in SalseData table, Department column
