Programming ASP.NET

I'm still on my little side trip from R2 into Programming ASP.NET, which is a great walkthrough of all the controls... I'm making one massive page with all my controls on it: AWESOME. Today, besides the book exercises, I learned...

• use the StringBuilder instead of just concatenating, in order to save memory.
• if you want onchange for radio or checkbox lists to change something (without AJAX) you must set AutoPostBack to true.
• There's no "NotSet" value for BulletedListDisplayMode even though the book example says there is - you just use Text. See MSDN
