Problem with Report viewer control

Question

I have a report viewer control,from which i need to generate mutiple reports for all the records that i am getting from my store procedure.For this,i tried 3 options.
1.Place the main report in a table detail(which will be in another report) ,and pass the Uid(unique identifier)
  to that table.
  Result--> giving an exception which says "exception unhandled by user code"
2.Tried the same thing as 1st with a list instead of table.
  Result--> giving the same kind of exception.
3.Placed the main report in another report making this main report as subreport.
  Result-->Only one report is being displayed for the last record that i get from my store procedure.
Please let me know if you have any solution, or
please advise any other option.I will give a try.
