When notified by this method, the UserControl must perform any initialization steps that are required to create and set up an instance. This method confirms site information associated with the UserControl instance and ensures that the class is initialized correctly as a UserControl object.
In this stage of the user control's lifecycle, the control's view state has yet to be populated. Additionally, you cannot access other server controls when this method is called, 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.
