XNA Game State Management

Question

I'm trying to develop an app using XNA and for state management I'm using the sample provided by the XNA Creators Club here - http://creators.xna.com/en-US/samples/gamestatemanagement

My app will be something like this:

IntroScreen --> Menu --> AppScreen
                     | 
                     |-> SomeOtherScreen
                     |
                     |-> CreditsScreen
                     |
                     |-> Exit

The AppScreen will show more info about a item that was selected from a listbox in Menu So in Menu i have a list whit lots of items(about 1000) and the users selects one and when he clicks a button the AppScreen will come showing that item and additional info about it.
Now my question is how can i pass a parameter(the item id) to the AppScreen from the Menu?

Anybody having experience with XNA that can point me into the right direction?
Thanks.

The same way you would with any other object. If you have a single copy to the app screen then have the Selected event also set up item number. If you create a new app screen then have the ctor take the item number.
