推荐答案

您还需要为子报告设置数据源。在这里，阅读子报告部分：在.Net中使用Crystal Reports [ ^ ]

You need to set up datasource for the sub report too. Here it is, read the "Sub report" section: Working with Crystal Reports in .Net[^]

dim CrReport as New CRmain
 
CrReport.SetDataSource(DTable)
 
RptViewr1.Reportsource = CrReport
 
RptViewr1.refresh()

这种方式...

this way...

   Dim orpt As New ReportDocument
...
   orpt.Subreports("HeaderRpt.rpt").SetDataSource(HeaderDT)
