How to bind a calendar control to a datasource

In my application, user will enter some meeting dates in one page.   In the details page, they need to see those dates to make a selection for one file number. I want to show a calendar in the details page whice will show the dates already entered. To do that I need to bind the calendar to a datasource to get the information from the database. Please guide me to do that.
Thanks in advance,
