See my second reply. I think in your case you can not use QueryParameter, ControlParameter, FormParameter or ProfileParameter. That leaves you only to generic parameter and setting its value in code behind. In my blog in the very end I gave a link to the parameter's definition. Check, if any of parameter's types may be applied in your case...
