title: Check if sender is @Html.ActionLink
body: <p>I have this method:</p>
  
  <p>   </p>
  
  <pre><code>void myMethod(object sender, DownloadStringCompletedEventArgs e)
      {...}
  </code></pre>
  
  <p>And I call it sometimes by @Html.ActionLink and sometimes by clicking on a cell in table which has the class 'clickableCell'.
  How to check what was the sender, if it is a link?</p>
  
  <p>It's type in both cases is WebClient.</p>
