Ok I am sorry to say, but your question is framented, and a little vague.
The page_load event does not fire when you use the back button. This event only fires on a Refresh or first time to the page. Back button relies on the browser cache.
To retain the CustomerID for what ever purpose, I would just use a session variable.
Session_Start
Session("CustID") = 0
Then in the first query on the DB, you reassign the retrieved value to th Session object.
Not sure whatelse you are asking for?
