What is an event?

As you are aware in real life an event is when something notable occurs such an earthquake or somebody walking on the moon, even you getting out of bed this morning could be considered an event! Within an ASP.NET page events are just the same, they mark something notable happening during the pages execution lifecycle and let you know about it when it happens. A prime example of this is Page_Load, this is raised early in the pages lifecycle and you can place your own code into the Page_Load event procedure.
