-//notes: view state only tracks changes after OnInit method is executed for the page request. You can read from it at any time, but cant write to it during rendering.
-//even more notes: view state info in trackviewstate method description. read later.
-//Ok, enough notes: what the heck is different between enable view state, and track view state.
-//Well, maybe not. How does the ViewState know when to track changes? Does it look at the property
-//on the owning control, or does it have a method/property of its own that gets called?
-// I think this last question is solved in the Interface for it. Look into this.
-
-//cycle:
-//init is called when control is first created.
-//load view state ic called right after init to populate the view state.
-//loadpostdata is called if ipostbackdatahandler is implemented.
-//load is called when control is loaded into a page
-//raisepostdatachangedevent if ipostbackdatahandler is implemented.
-//raisepostbackevent if ipostbackeventhandler is implemented.
-//prerender is called when the server is about to render its page object
-//SaveViewState is called.
-//Unload then dispose it apears. :)
-
-//Naming Container MUST have some methods. What are they? No clue. Help?
