sub report is not working for RDLC VS2010 report using VB.NET 2010

Hi,

I'm working on VS2010 rdlc report. my work is to convert all crystal reports into VS2010 rdlc report.

I have completed all the possibility of report conversion. now i am confusing and has problem in sub report concept of rdlc.

Actually there is one main report and i have 26 sub reports available for this main report. I am using add hander in VB.NET 2010

AddHandler objRPTVWR.ReportViewer1.LocalReport.SubreportProcessing, AddressOf CD01SubreportProcessingEvent

for every 26 subreport.

In every CD01SubreportProcessingEvent procedure i'm executing select query using dataset and assign to e.datasource like,

 e.DataSources.Add(New ReportDataSource("dsSoxInpDtlAuditCD01", l_dsRptCD01.Tables(0)))

So, I need complete set of coding help for sub report calling in VB.NET 2010..

Thanks,
