What is the ‘page lifecycle’ of an ASP.NET WebForm?

I’m looking to get a more thorough understanding of the ASP.NET page lifecycle. I’m in the process of building custom form controls and have found my knowledge in this area to be lacking.

  • Are there any resources, tutorials, etc. that you’ve used to better understand this area?
  • Are there any tools you’ve used to improve your knowledge in this area?

    Method 3

    This is the “original” MSDN overview. Pretty good:

    Honestly, you shouldn’t need our help to find these things. Try Google.

    Method 4

    This diagram is specifically helpful in determining the order of events, but doesn’t elaborate on them in any detail.

    Method 5

    This doesn’t directly answer the Page lifecycle question but this covers the Global event lifecycle with events like BeginRequest and EndRequest. It’s good to understand how those work in relation to Pages.
