title: Inline script does not resolve in ASP.Net custom control
body: <p>Currently I am working with a <strong>custom</strong> regular expression validator <em>(unfortunately)</em>.</p>
  
  <p>I am trying to set the Regex pattern using a server side inline script like this:</p>
  
  <pre><code>ValidationExpression="&lt;%= RegExStrings.SomePattern %&gt;"
  </code></pre>
  
  <p>However, the script is not resolving to server side code. Instead it is being interpreted literally and I end up with something like this in the rendered markup:</p>
  
  <pre><code>ctl00_DefaultContent_regexValidatorInvitation.validationexpression = "&lt;%= RegExStrings.SomePattern %&gt;";
  </code></pre>
  
  <p>Any clues as to why this is not resolving properly?</p>
