When notified by this method, server controls must perform any initialization steps that are required to create and set up an instance. In this stage of the server control's lifecycle, the control's view state has yet to be populated. Additionally, you can not access other server controls when this method is called either, regardless of whether it is a child or parent to this control. Other server controls are not certain to be created and ready for access.
