水晶报表中不显示数据源里数据怎么办

[lanniaofeixiang]

这是我代码
Dataset2 ds = new Dataset2();

string sql = "server=.;uid=sa;pwd=hykj;database=Northwind";
SqlConnection conn = new SqlConnection(sql);
conn.Open();

string sqlNew = "select * from Orders";
SqlDataAdapter da = new SqlDataAdapter(sqlNew, conn);
da.Fill(ds, "Orders");

CrystalReport1 cr = new CrystalReport1();
cr.SetDataSource(ds);

this.crystalReportViewer1.ReportSource = cr;
this.crystalReportViewer1.RefreshReport();

conn.Close();
望解答,谢谢

最后的一句
conn.close 先注释掉，然后最后加一句
this.crystalReportViewer1.showdialog
