To add to previous answers; the automatic hooks are applied from TemplateControl.HookUpAutomaticHandlers. This method calls into TemplateControl.GetDelegateInformationWithNoAssert which contains which methods are considered as event handlers.

These are, in System.Web, version 2.0:

• On all classes deriving from Page: Page_PreInit, Page_PreLoad, Page_LoadComplete, Page_PreRenderComplete, Page_InitComplete, Page_SaveStateComplete.

• On all classes deriving from TemplateControl: Page_Init, Page_Load, Page_DataBind, Page_PreRender, Page_UnLoad, Page_Error.`

• Transaction support for all classes deriving from TemplateControl:

  • Page_AbortTransaction, or if it does not exist, OnTransactionAbort
  • Page_CommitTransaction, or if it does not exist, OnTransactionCommit

System.Web, version 4.0, introduced a Page_PreRenderCompleteAsync for all classes derived from Page. That method, if present, will be registered using Page.RegisterAsyncTask and executed automatically "just before the PreRenderComplete event" (source: Page.ExecuteRegisteredAsyncTasks). This method seems very undocumented which suggest that it would be prefered to just call Page.RegisterAsyncTask with your own method instead.
