水晶报表的子报表绑定数据源无数据显示

[xiaobao1981]

大家帮看一下，我在报表中插入了4个子报表，想分别给每个子报表设置数据源。(数据之间不相关)，

我在FormLoad事件中加入以下代码
pregnancyAgeDsFram pads = new pregnancyAgeDsFram();
pads.Load(Application.StartupPath + "\\pregnancyAgeDsFram.rpt");
SubreportObject objFamilyReport;
objFamilyReport = pads.ReportDefinition.ReportObjects["FamilyReport"] as SubreportObject;
ReportDocument familyReportDoc = objFamilyReport.OpenSubreport(objFamilyReport.SubreportName);
familyReportDoc.SetDataSource(ds.Tables["tbManWife"]);

DataSet ds1 = db.RunProcReturn("select * from woman_hy where id=3523","tbhy");
SubreportObject objPregancyReport;
objPregancyReport = pads.ReportDefinition.ReportObjects["PregancyReport"] as SubreportObject;
ReportDocument PregancyReportDoc = objPregancyReport.OpenSubreport(objPregancyReport.SubreportName);
PregancyReportDoc.SetDataSource(ds1.Tables["tbhy"]);

this.crystalReportViewer1.ReportSource = pads;

程序运行后，一点反映都没有？弄了很长时间了，大家帮帮我啊，急。
