Line 255:

The article refers to "clean code" without a link. Quotation marks are around "clean", but not "code". If this is a reference to [[Robert C Martin]]'s concept of clean code, I recommend extending the quotation marks to surround both words, and making that a link, either to an article on clean code, or at least to the one on Martin.

== Information about ViewState incorrect ==

The viewstate does not track form values, it's a source of confusion amongs a lot of ASP.NET programmers.

Form values are already sent with the postback data, so these don't have to be in the viewstate. See:

* http://msdn.microsoft.com/en-us/library/ms972976.aspx

* http://weblogs.asp.net/infinitiesloop/archive/2006/08/03/Truly-Understanding-Viewstate.aspx

Viewstate only has to contain the state which changed from the defaults set in the ASCX files and OnInit() method. That includes:

* modifications by a event handler (e.g. showing an panel after a OnClick event -> the Visibility has to be tracked and restored)

* modifications by the `Page_Load()` event.

As critism to Microsoft, this behaviour is IMHO not communicated clearly.

Programmers fill the default Page_Load() method, and end up with a huge ViewState.

This state is transmitted back and forth with every page request, causing performance issues.
