RDLC 如何嵌套多级子报表

[kaichhuang]

RDLC 如何实现子报表中嵌套子报表？？

[愚知]

1 显示标头 标尾《传给2参数a》

1 2 数据行 《接收1传的参数a》

1 2 3 数据行《接收2传的参数b》

这样的层级结构明白？

[kaichhuang]

localReport.LoadReportDefinition(_service.GenerateRdlc(Server.MapPath("~/mainReport.rdlc"), false));
localReport.LoadSubreportDefinition("subReport", _service.GenerateRdlc(Server.MapPath("~/subReport.rdlc"), true));

如果 ~/subReport.rdlc 里也嵌套了一个 子报表 如：~/subReport1.rdlc

这个该如果处理呢？？？

代码好多。。看的眼都花了，我这种不太会编程的新手还是默默用finereport吧。。向大神学习学习。
