event models
my partner-in-crime Mike Palermo and i are currently developing some new courseware. this course, Advanced ASP.NET, will provide students a more in-depth look at the underpinnings of the ASP.NET development paradigm. one of the things we're going to cover in this class is an advanced, deep view of the event model. explicitly, we're going to carefully go over the order of priority with the application, page, and control events that automatically fire during every page load. during demo-code development, i created a series overridden functions in a simple control, a page containing that control, and the global.asax file's codebehind that lives within the web application where the form is executing.
for the sake of brevity, here's the output of the code. it shows you - with pretty much no room for confusion - the order in which all of the events fire. thought some would consider this helpful. remember - this text was generated in the order the overrides are processed on the server. to put it in a non-techy way, this is about as “straight from the horse's mouth“ as you can get:
