    It's hard to tell from your message WHEN and WHERE you want to re-use these
    variables, and that makes all the difference in terms of how you would
    store/persist them. The Page class is re-instantiated and destroyed with
    each Page request. So, if you don't need the values to survive PostBacks
    (for example, if you want to use them in the Page_Init and Page_Load
    methods), you can store them in the class as fields or properties. If you
    need them across PostBacks, but only within the one Page, you can store them
    in ViewState. ViewState is maintained by using a hidden form field in the
    client, which is posted back to the server and updated with each PostBack.
    Note, however, that, as ViewState is rendered in a hidden form field in the
    Page, it's not a good idea to store anything very large in there. If you
    want to use them across multiple pages, but only for a single user Session,
    then storing them is SessionState makes sense. If you want them to be
    globally available to all Pages and all user Sessions, you can store them in
    ApplicationState.

    There are a few other places as well, but this hits the high points.

    Thanks! Exactly what I need to know! In my case it is postbacks so I
    think I can use viewstate for this.
