Have you tried View --> Report Data? Then you should see Parameters in the Report Data window. This is how I get to the parameters in VS2010.

Just a quick remark for people using VS2008: open the RDLC in the designer and a Report main menu item should appear. The first sub-menu item is Report Parameters. You can configure the parameters from there.
