Whil Hentzen said years ago, "If it's easy for the user, it's hard for the developer". You can set a data annotation for the minimum date, but it won't affect the data picker AT ALL. If you want to limit the selectable dates in the date picker, you need to code it into the javascript. Go with what works.

As for the CDN issue, perhaps it's a different version than what you have locally. It's going to make it faster for the user, but probably not significantly.

>date seems to work Ok even in IE9 now and also the Ajax style seems to be working for my Index.chtml. If I comment the first one out and try to use the one from CDN, the Ajax style stops working, although date seems to still work in IE9, which is good.
