10 Operation of built-in ASP.NET handlers associated with* GET /somefile.ext somefile.ext gen d code user code HTTP/ OK... produces* compiled into.net Class Instance instantiate & call to produce response

Operation of built-in ASP.NET handlers somefile.ext GET /somefile.ext.net Class HTTP/1.

14 ASP.NET Web Pages Control-based framework for productive means of generating HTML Author a.aspx file Use designer/text-editor to add controls, HTML and set properties Write Page class in code-behind

15 From text file to compiled code

16 From.ASPX file to compiled code GET test.aspx System.Web.UI.Control controls collection System.Web.UI.Page ProcessRequest() test.aspx generates & compiles test_aspx void FrameworkInitialize() { controls.add( new LiteralControl( <html><body>... )); }

17 A page is a tree of controls render (HtmlWriter) Page Render() Control Control Control Control Render() Render() Control Render() Render() <html> <body> <ul> <li> <li> </ul> <input/> <a/> </body> </html> Render()

18 A page contains a form

19 Pages (generally) post to themselves GET /default.aspx Page Control Control Con HTTP/ OK... Control Control IsPostback = True POST /default.aspx Page Post Data Control Control Con HTTP/ OK... Control Control

20 At post-back, controls fire events

21 Controls appear to maintain state GET /default.aspx POST /default.aspx Post Data POST /default.aspx Post Data (incl VIEWSTATE) Apply VIEWSTATE

22 Pages go through a life-cycle

23 Lifecycle of a Page (simplified) Init CreateChildControls, ViewState loaded (for post-backs) Unload CreateChildControls (for non-post-backs) Load ViewState saved Render Pre- Render Server-Side events fired (for post-backs)

24 Page Feature Areas Data Binding Caching Login Features Session Profile Validation Navigation
