DropDown List problem?

[Maximus]

Hi Everybody,

I have a dropdwonlist on a .aspx page when I select an item it fires the
OnSelectedIndexChanged Event and where I redirect myself to a different
page. Now I click the back button of the browser and select another item
from the dropdownlist, but now the OnSelectedIndexChanged Event is not
fired. I am confused why it would'nt do it. Should it ideally do it if
yes then why doesnt it happen in my case. If not is there another way I
can fire the event.

Any help will be greatly appreciated.

Thanks.
