Passing multiple value for parameter

[hariomhari]

I am using ASP.Net 2005 and CR XI Release 2 version.

I have written a separate module in .Net for report execution and display. Then, I am using a URL to display report :

Response.Redirect"/FINModule/Reports/Report_Launcher.aspx?ReportID=" & ReportID & "&PortfolioID=" & PortfolioID & "&Strategy=" & Strategy & "&Custody=" & Custody & "&OutputFormat=pdf")

The PortfolioID, Strategy and Custody are the parameters in report.

I want to pass multiple values for a parameter say for Strategy and want to allow user to filter the data.

How can I pass the multiple values for a parameter. Please suggest with example.

Thanks,
