I just got the 05 upgrade and I'm a little unclear on some things.  I understand the basic concept of partial classes, but I haven't seen any examples of implementation where the logic for 1 page is split among many files.  Would it be that if I had default.aspx I'd have a default.aspx.cs file and then I could create a default_extras.cs and both of the cs files were marked as partial class default? 

Also, what happened to all of the page control declarations.  It used to be at the top above the page load that all variables and controls were declared, but I don't see that anymore.  Is there another file that this info is stored in?  If so, can I still declare controls above the page load method which might not actually be on the page yet but would be dynamically created later?  Thanks.
