title: Change the content of a Css Class through Code Behind in asp.net
body: <p>I need to change the CONTENTS of a css class through asp.net code behind. The reason why I need to do this is because i have an external user control that uses a property called "stylefolder" instead of the normal cssclass.</p>
  
  <p>I'm really out of ideas, I tried to open the css file and replace text, but then after i also need to save it. So the css file is permantly modified which I don't want.</p>
  
  <p>Please help</p>
