When visitors are navigating through your site and they need to make a selection from a control with fixed values, it is best to have the control automatically post back. This makes navigating your site quicker as the user does not have to click other buttons to see the changes which they have made. It is also important to remember that controls which do not have set values, such as text boxes, should have a "Show" button available to click once the visitor is finished entering their data.
