Form_Load() 'event' or Override OnLoad()

Question

I would like someone to try and explain the difference between these. More specifically, example usage scenario\'s.

I am refactoring some Windows Form

Answer 1

When overriding OnLoad, the call to base.OnLoad invokes the Load-event of the Form.

protected override void OnLoad(EventArgs e)
{
  // do stuff before Load-event is raised
  base.OnLoad(e);
  // do stuff after Load-event was raised
}

If you don't specifically need to perform stuff before the Load-event is raised, placing the code in OnLoad after base.OnLoad(e) gives the same runtime behaviour as placing it in the Form_Load event handler.

I would recommend overriding the method rather than subscribing to the event.
