Hi Patrick,
Postback is a mechanism to provide that you can do server-side actions. Some
actions can be handled on the client side, meaning they don't require
anything to be processed on the server side. (For example showing a mouseover
image effect.) On the other hand, sometimes you need to do more complex
things which you cannot do on the client side. (For example, changing a data
source on the server side.) Because of this need, there's the postback
mechanism. The page "posts" back the page to the server. (As the name
implies, this is a POST, not a GET). I recommend that you use the following
link as a starting point to get more insight how pages are processed and the
event model;

Hope this helps,
