This is scheduled for future versions of Sitefinity, and it's on the web site by mistake. We have removed it. There is a way this to be achieved though - since the RadControls come with Sitefinity, you should use the RadScheduler control and bind it to the list of events. The events can be taken with the API.
Let us know if you need help on this, so that we can assist with a code sample.
I hope this helps.
