title: input type file, trigger the popup by a button click only
body: <p>I have this file upload control: </p>
  
  <p><img src="https://i.stack.imgur.com/6K5DK.png" alt="enter image description here"></p>
  
  <p>Which has this markup:</p>
  
  <pre><code>&lt;div class="controls"&gt;
      &lt;input name="attachments[]"  id="attachment_control" runat="server" type="file" /&gt;&lt;br /&gt;     
      &lt;div id="fileuploads" runat="server"&gt;&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to somehow fix this control to have the popup shown only on the <kbd>Browse</kbd> button click. As it is now, anywhere you'll click in the control, the upload popup will be shown, but I want only when the user will click on the button, the popup to be shown. </p>
  
  <p>How can I do this?</p>
