A:
When using the back button the browser displays a cached version of your page. It does not send a new request to your server. This is why your Page_Load is not firing.
You may want to take a look at HttpCachePolicy.SetCacheability that allows you to control caching.

I add this Line Response.Cache.SetCacheability(HttpCacheability.NoCache);and tha back works correctly between pages but when I raise event in the same page and then click back it give me message " expired web page"

You will get the "expired web page" because the browser cannot do a HTTP POST when pressing back.

A:
I suspect you need to ensure the page is not cached in the brower.
An HTTP header such as
Cache-Control: private, max-age=0
should achieve that.
Although different web browsers may implement this differently, and it is possible a user's settings may override the HTTP header directives.
(This is speculation, I have not tested this)
Coding your app in such a way as to not rely on the page load event would be much better.
