page load after postback - how does it know?

Looking at the locals I have "ME" and "sender". I've just clicked on a
dropdownlist and it's fired a post back. I'm in the page_load. I know
that after the page_load is complete it will fire the click event
handler for my dropdownlist, which indicates, since I've got several
of these, that it knows which one fired.

The question is: How does it know? Is there something in "Me" or
"sender" that tells it what I clicked on? This seems to me to be a
fairly rudimentary question, yet I'm not having any luck finding an
answer via the usual search mechanisms.
