请教:有谁知道Reportviewer 制作子报表的.在下遇到困难了.
Dim adapter As New System.Data.SqlClient.SqlDataAdapter
Dim cmd As New System.Data.SqlClient.SqlCommand
Dim cmdstr As String = _
"select * from SendSubTicket where mainID in (select intID from SendMainTicket) "
cmd.Connection = GlobalBase.current.connection
cmd.CommandText = cmdstr
adapter.SelectCommand = cmd
adapter.Fill(Me.DsSendTicket1, "SendSubTicket ")
cmd.CommandText = "select * from SendMainTicket "
adapter.SelectCommand = cmd
adapter.Fill(Me.DsSendTicket1, "SendMainTicket ")

Me.SendSubTicketBindingSource.DataSource = Me.DsSendTicket1
Me.SendSubTicketBindingSource.DataMember = "SendSubTicket "

'主报表数据源
Me.SendMainTicketBindingSource.DataSource = Me.DsSendTicket1
Me.SendMainTicketBindingSource.DataMember = "SendMainTicket "

Dim streamRder As New System.IO.StreamReader( "E:\Soms.Net\Soms.Manager\Reports\SendsubTicket.rdlc ")
streamRder.ReadToEnd()
System.Diagnostics.Debug.Write(streamRder.ToString())

ReportViewer1.LocalReport.LoadSubreportDefinition( "SendsubTicket.rdlc ", streamRder)
Dim myReportDataSource1 As Microsoft.Reporting.WinForms.ReportDataSource = _
New Microsoft.Reporting.WinForms.ReportDataSource( _
"SendSubTicket ", Me.DsSendTicket1.Tables( "SendSubTicket "))

Me.ReportViewer1.LocalReport.DataSources.Add(myReportDataSource1)


Me.ReportViewer1.RefreshReport()


子报表就是不能显示出来...不知道是我做错了..还是..怎么的
有谁做过吗..

[解决办法]
了报表没有数据还是什么情况?
[解决办法]


CrystalReport1 Cr1 = new CrystalReport1();
Cr1.SetDataSource(ds.Tables[ "XXX "]);
Cr1.Subreports[0].SetDataSource(ds.Tables[ "X1 "]);//这是子报表1,填充的是数据表X1
Cr1.Subreports[1].SetDataSource(ds.Tables[ "X2 "]);//这是子报表2,填充的是数据表X2
...
this.crystalReportViewer1.ReportSource = Cr1;
