A popup calendar control would be a nice addition.
Some examples could have functionality like the
following:
1. ComponentArt Popup Calendar (ASP.NET)

2. RJS Popup Calendar (Free)

3. Dynarch DHTML/Javascript Calendar (Free)

4. The Atlas approach would also work. With Panel and
Extender controls embeds a Calendar control. The
panel extender attaches to a textbox.
