Dim ckllbrptsql As String = "select * from ckllb where 年份='" & nstr & "' and 月份='" & ystr & "' "
Label2.Text = ckllbrptsql
Dim bbclcmd As New OracleCommand(ckllbrptsql, llbrptconn)
bbclcmd.CommandType = CommandType.Text
bbcla.SelectCommand = bbclcmd
bbcla.Fill(bbcls, "ckllb")
DataGrid1.DataSource = bbcls.Tables("ckllb")
Dim llbRpt As New pjckllqkb
llbRpt.SetDataSource(bbcls.Tables("ckllb"))‘设定报表数据源。已经设好pjckllqkb格式和相应公式
Me.CrystalReportViewer1.ReportSource = llbRpt
llbrptconn.Close()
执行后， DataGrid1显示正常，而CrystalReportViewer1却显示为空，请问为什么？？？
怎样解决？
