title: Use inline Request.QueryString to build url
body: <p>Not sure if I'm asking this right, but I have this:</p>
  
  <pre><code>&lt;a href="mypage.aspx?id=&lt;% Request.QueryString["id"].ToString(); %&gt;&amp;sec=map"&gt;
      Map
  &lt;/a&gt;
  </code></pre>
  
  <p>But it doesn't add the ID to the url query string. Not sure what to do cause I really don't want to have to make a bunch of literals to build this on code side.</p>
  
  <p>The url I get is:</p>
  
  <pre><code>mypage.aspx?id=&amp;sec=map
  </code></pre>
