ASP.Net page events when master page included

When using master pages, the normal page event lifecycle is a little different. Here is the actual order:

Page: OnPreInit
MasterPageControl: OnInit
Control: OnInit
MasterPage: OnInit
Page: OnInit
Page: OnInitComplete
Page: LoadPageStateFromPersistenceMedium
Page: LoadViewState
MasterPage: LoadViewState
Page: OnPreLoad
Page: OnLoad
MasterPage: OnLoad
MasterPageControl: OnLoad
Control: OnLoad
OnXXX
MasterPage: OnBubbleEvent
Page: OnBubbleEvent
Page: OnLoadComplete
Page: OnPreRender
MasterPage: OnPreRender
MasterPageControl: OnPreRender
Control: OnPreRender
Page: OnPreRenderComplete
MasterPageControl: SaveControlState
Control: SaveControlState
Page: SaveViewState
MasterPage: SaveViewState
Page: SavePageStateToPersistenceMedium
Page: OnSaveStateComplete
MasterPageControl: OnUnload
Control: OnUnload
MasterPage: OnUnload
Page: OnUnload



Complete Flow Of Application,Control and Page Events

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...
