各位大虾,请帮个忙,我做了一个GridView显示一个表1中的数据,通过表1中的关键字GCRCLMLH,作为选择,通过水晶报表显示出表2和表3中的部门数据.其中表2和表3和表1都是通过关键字GCRCLMLH作为主外键的.可是现在我点选择,总是提示我水晶报表生成失败,不知是什么原因.

sqlAdapt = new SqlDataAdapter(sqlStr, conn);
DataSet1 dt1 = new DataSet1();
sqlAdapt.Fill(dt1, "myTable");
myReport = new ReportDocument();
myReport.Load(Server.MapPath("../CG.rpt"));
myReport.SetDataSource(dt1);
CrystalReportViewer1.ReportSource = myReport;}
