Should override OnLoad() and call base.Load() before Load event or after in UserControl?

In OnLoad override method. there's base.OnLoad()

Should it called first or call it last after all custom code goes there?

    protected override void OnLoad(EventArgs e)      {          // COde here?          base.OnLoad(e);          // or Code Here?      }  

Also many questions asking about Constructor vs Load event for User Controls in WinForms. Problem here that ParentForm not accessible in Constructor. and also all custom properties not accessible in constructor it all return null. but after Form_Load it readed. So why many suppose to use constructor? and other suppose to be it must all inside Load event. But as we know that Load event maybe manipulating any form variables makes a Refresh control multiple-times. which mean more slowly. Is there any overcome to that so constructor can forcibly access all properties and ParentForm property.
