It appeared to me that they added a few things here and there to the Application, Page and Control lifecycle in ASP.NET v2.0. Curious, I whipped up some derived classes to output to a text file every time one of these events fired in the grand scheme of a request. I wired in the basic events then did overrides for everything that appeared to fire at some point. I think it's mostly complete, but the data binding events don't appear to fire unless you've got some data binding to do...
Edit 7/4: I added the postback events in there, as well as data binding for the control. However, keep in mind that the data binding for the control is, in this case, called from the page's Load handler. Naturally it's common to do this in PreRender as well, so it could also appear there.
Anyone have something to add?
