User controls are reusable controls that can be defined
once and used whenever we need them, in any of the .aspx
pages of our application. We do have skins,themes and
css to give a standard look to our website. User
controls help to achieve that as well because since we
define them once and use many times, thus making sure we
do not have same controls on pages looking differently.
When we make changes to a user control all these changes
will be reflected to all instances of the control.
