The way I prefer is to use the On method instead, so type override
OnLoad to setup the load event handler, OnPreRender, etc. Each of these
methods essentially calls the respective event handler, as in:
protected override void OnInit(EventArgs e)
base.OnInit(e); //don't remove
I also think you can add an event handler manually:
protected void Page_Init(object sender, EventArgs e)
Without needing to set anything up for this (no explicit listening for the event), but I'm not 100% sure of this.
