经常会有这样的问题存在，纠结中。。。。。。。。。
[最优解释]
OutOfMemoryException
内存溢出了，是不是你的数据量太大了
[其他解释]
如1楼所说，在报错的时候，检查下你的SQL语句返回的数据集的数据条数看看。
[其他解释]
在设计报表的时候，我用的是子报表。。。。用的原因也是为了解决数据量太大。结果成功显示了，在后台cs文件里面，我的代码
SqlConnection cn = CommonClass.getConnection();
cn.Open();
DataSet ds = new DataSet();
string sql;
sql = "select ID,SIZE from B_Size where isdel=0";
SqlDataAdapter da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "B_Size");
sql = "select ID,Tool from B_Tool where isdel=0";
da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "B_Tool");
sql = "select ID, ProType from B_ProductionType where ISDEL=0";
da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "B_ProductionType");
sql = "select ID, step from B_Step where ISDEL=0 order by orderid ";
da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "B_Step");
sql = "select ID, PanelType from B_PanelType where ISDEL=0";
da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "B_PanelType");
sql = "select ID,panelid,protypeid,paneltypeid,stepid,offlinetime,panelsizeid,toolid,processingtime,redo,scrap,startloadtime,trackintime,trackouttime,warningtime from D_RunTracking where convert(varchar(10),trackouttime-8.5/24,120)='"+DTdate+"'";
da = new SqlDataAdapter(sql, cn);
da.Fill(ds, "D_RunTracking");
ReportDocument report = new ReportDocument();
string reportPath = Server.MapPath("J_RunTracking.rpt");
report.Load(reportPath);
report.SetDataSource(ds);
CrystalReportViewer1.ReportSource = report;
CrystalReportViewer1.DataBind();
tag = "first";
cn.Close();
它并不是一开始就有这个错误，有时候有有时候没有，ds里面有多张表，他们在后台不是也是笛卡尔积相乘吧，那怎么办呢？？？？

还要回复才能看啊
