Back in the classic ASP days, I had developed an events calendar for a company to allow there customer to view what was happening with them through out the months. Since then, asp.net 1.1 and 2.0 came out allowing developing an asp.net events calendar a lot easier then back in the classic days.
So a while back, I decided to develop one in asp.net 2.0 and AJAX to use for my personal and professional use.
