If you want to do it via a post back you can place the calendar control inside a panel and set visibility to false. Setup a button with on its click event to set the visibility to true and on the selection changed for the calendar event have it populate the box you want it to followed by the command to hide the panel again.
If you want it do it dynamically then you will need to look into AJAX. That will require some in depth Java or Atlas with the Atlas Toolkit.
