Answer 1

It plays the role in the lifecycle of a page request to ensure all controls generated dynamically/via code are in place for binding postback values and rendering out to the page. Also note from the MSDN page :

When you develop a composite or templated server control, you must override this method.

You can check this page for the full list of events, in order, on an ASPX request.
