Get data from control state on the INIT event

What should we do to get the data in a control state of a page on the Init event after a postback is done?

You must keep in mind that the method(LoadControlState) that gets the data is automatically called when that method finishes and before the Load event starts similar to what happens with the viewstate and attributes.

Any ideas?
