title: send custom parameters to user control ascx
body: <p>I need to use user controls (.ascx) on a page, it's a related post user control based in 2 parameters:</p>
  
  <pre><code> 1. Current post
   2. Relation type
  </code></pre>
  
  <p>the page needs to have 3 different instances of this control, each having the same Current post parameter, but different relation type (title, author, genre).</p>
  
  <p>The 1st parameter I can get it through url, but what about the second parameter?</p>
  
  <p>I've been googling for a while but i haven't found an answer yet. How can I pass the second parameter so the control can load the information based on these parameters? 
  I'd rather not to create a control for each parameter, else would be better to build no user control but direct into code :(
  Thanks!</p>
