Remember, the web is inherently stateless. That means every page view is
like a brand new occurance of the page. The variables and data is generally
not kept. You have to store the variable somewhere to handle this sort of
thing. Luckily, ASP.Net has the Viewstate. You can store the variable in the
viewstate after you perform some work on it in button one, then retrieve it
in button 2 (and do some work with it again and store it, etc..). Whenever
you access a Viewstate item you'll need to check if it is null first, just
to make sure because if you haven't saved the variable to the viewstate then
it will come back as null and possibly mess up your code.
Hope this helps,
