A recent job interview with a very, very interesting company in Marina Del Rey, gave me the opportunity to review my way of approaching ASP.NET Web Forms. My way of approaching ASP.NET Web Forms in a professional conversation is deliberately disruptive and easily offensive. I want to offend “thought leaders” in Microsoft IT shops that may claim to appreciate jQuery and ASP.NET MVC but they actually do not and would actually prefer to work within the theory behind ASP.NET Web Forms. I don’t want to have a bait-and-switch kind of work-day-hell situation where I’m hired for an ASP.NET MVC/jQuery future but stuck in an ASP.NET Web Forms present. Simultaneously, I am willing to work with ASP.NET Web Forms as long as it is clear to me that no religious affections for Web Forms coming from the culture of the shop.

One red flag signifying such 1990s-based religious fervor is a request from an interviewer asking me to recite, from memory, the ASP.NET Page lifecycle and/or the IIS application lifecycle. Too many Microsoft shops use these rote memorization stunts as intelligence tests—and I have always been disgusted with such mis-measurements. But my disgust has prevented me from really thinking about an authentic response to this question that is respectful of my principles/theories and not ‘easily’ offensive to my inquisitors.

Instead of memorizing this from ASP.NET 2.0:

Application: PreAuthenticateRequest
Application: AuthenticateRequest
Application: PostAuthenticateRequest

Application: ReleaseRequestState
Application: PostReleaseRequestState
Application: PreUpdateRequestCache
Application: UpdateRequestCache
Application: PostUpdateRequestCache
Application: EndRequest
Application: PreSendRequestHeaders
Application: PreSendRequestContent

My “over-idealistic” principles lead me to know these points:

  • The ASP.NET Web Forms Page lifecycle consists of events that primarily allow granular control over Server Controls.
  • The ASP.NET Web Forms Application lifecycle consists of events that primarily allow control over security Authentication and Authorization.

It follows that any ignorance I might have about these lifecycles implies that:

  • I am inexperienced with using Server Controls—especially implementing custom controls.
  • I am inexperienced with using View State.
  • I am inexperienced with using advanced security scenarios with ASP.NET—especially implementing ASP.NET Membership/Roles/Profiles.

What too many Web Forms people sitting across from me in an interview don’t care to respect is that my inexperience with Server Controls and View State is by design. However, my lack of experience with ASP.NET Membership/Roles/Profiles is a sad consequence of my deliberate de-prioritizing Server Controls and View State. My career-level decision to essentially defer learning about these features of ASP.NET in order to go into ASP.NET MVC is the right future-focused strategy—no amount of sophomoric snickering will change that—but to get a job in the present I need to know a little more about the older, more proprietary features of ASP.NET.

Joe Stagner Actually Talks about ASP.NET Page Lifecycle

Instead of listing a bunch of events or showing a colorful poster of events, Joe Stagner of Microsoft actually talks about the ASP.NET Page lifecycle. When one is “forced” to talk about this subject, it becomes more human—therefore more relevant. Here are some points gleaned from Joe’s talk:

  • It may be best to classify Page events into three groups: Init, Load and Render.
  • The Init and Load event ‘groupings’ are divided into three logical granules PreEvent, Event and EventComplete. For example the Init grouping is PreInit, Init and InitComplete.
  • One important Application-level stage in ASP.NET is getting Request state (AcquireRequestState) where the Page.Request (and, according to Joe, the Page.Response) object is instantiated. Also, according to Joe, the Page.IsPostBack property is set here.
  • During PreInit, there is no View State set yet.
  • During PreInit, any dynamic server controls or master pages can be instantiated here. Any profile/theme properties can be set here.
  • Joe makes a point to mention that during the Init event, the Control.Init event fires for each child Control of the Page.
  • The InitComplete event is a granular opportunity to handle any View State issues. From the documentation: “Use this event to make changes to view state that you want to make sure are persisted after the next postback.”
  • The PreLoad event represents the time when View State is reconstituted (so it has a logical relationship with SaveStateComplete which fires at the end of the Page lifecycle).
  • The LoadComplete event is a granular opportunity to handle any communication among child controls.
  • The PreRender event calls EnsureChildControls for the Page and child controls.
  • The PreRenderComplete event is a granular opportunity to handle any data binding issues.
  • The Render event is the obvious one.
  • The Unload event is not so obvious to me—but it should be: this is when the page is just about to be returned to the client so it’s a time for cleanup.

What should be authentically memorable to me is that these lifecycle events are where developers interact with all of the features of ASP.NET. So a developer that has memorized the lifecycle is one who has used almost all of the features of ASP.NET extensively (repeatedly, maybe violating DRY principles)—or just some dude with great memorization skills.

Mike Ormond’s Blog: “Yes indeed. Now you can have your cake and eat it—almost. We give you control over the ClientIDs generated by server controls. ASP.NET does an excellent job of avoiding naming conflicts in the HTML document through the use of naming containers that guarantee uniqueness for a certain context. The result though, can be lengthy, complex and (importantly) difficult to predict ClientIDs. …This can make life a misery if you’re doing DOM manipulation in Javascript as you typically revert to some inline code to extract the ClientID. You’ll find littered all over the place. Given the surge in popularity of AJAX and client frameworks like jQuery, the pain caused by this “guarantee of safety” is becoming more acute.”

Random Screenshot: A “Blank” SharePoint Site in a GNOME Folder

So let’s take a peek at what Windows SharePoint Services (WSS) generates for a “Blank” Collaboration Site. What jumps out at my inexperience with the inelegant innards of SharePoint is the absence of .ASPX files. There’s locale resources, some FrontPage-looking (WebDAV) stuff, some kind of browser capability database (see “Add Blackberry support to Forms Server 2007 or SharePoint 2007”), a *.DLL file for SOAP, a *.DLL file for ‘application pages,’ two different web.config files and the global.asax file that is probably doing most of the heavy lifting.

I assume the rest of the site is in the Content Database. And, oh, by the way, I had some kind of disk catastrophe yesterday and lost a 300meg WSS Content Database! Because the log had some open transactions I could not recover the database. I got almost everything back as disk files (not in SharePoint) from a backup.

In the second month of 2008 came “Mono Uninstalled (for the moment)” and I tried again egged on by these links:

The bottom line is this: I am unable to locate any documentation about the lower limit of GTK support for MonoDevelop. And I write ‘GTK’ with the very real possibility that I am blurring GTK into GTK#. My strong suspicion is that my current version of Ubuntu (6.0.6) has a hard Gnome GTK limit (without serious mods) (which is why I cannot run Firefox 3.x)—and that the current 1.0 version (and future versions) of MonoDevelop will simply not run on it.

This implies upgrading Ubuntu. Sounds “easy” but it should be known that, according to VMware “Supported Guest Operating Systems,” the latest version of Ubuntu is not supported by VMware Workstation 6.x—and I’m using Workstation 5.x!
