title: Loading user controls dynamically
body: <p>How to load a user control dynamically in a page?<br>
  I have a page that contains radioButtons. Each click on a radio button loads a user control (.ascx) in the page.<br>
  What I am doing is loading all controls at the same time, but set their visibility to false. When a user clicks a radiobutton I set the visibility of the specific user control to true.<br>
  As a result I am loading all the user controls on each postback.<br>
  Is there any other possible way of doing this?</p>
