Question: In what order do the events of an ASPX page execute. As a developer is it important to understand these events?

Answer: if you try to access it in Page_Load that is way earlier than Control's own
Render method. See ther Page/control lifecycle goes like this for the Page
and controls (being already in the controls collection, dynamic ones play
catchup)

1. Instantiate
2. Initialize
3. TrackViewState
4. LoadViewState (postback)
5. Load postback data (postback, IPostBackDatahandler.LoadPostdata)
6. Load
7. Load postback data for dynamical controls added on Page_Load (postback)
8. Raise Changed Events (postback,
IPostBackDatahandler.RaisePostDataChanged)
9. Raise postback event (postback, IPostBackEventHandler.RaisePostBackEvent)
10.PreRender
11. SaveViewState
12. Render
13. Unload
14. Dispose
null
