title: What is readonly for in a disabled TextBoxFor?
body: <p>I have two different ways to use a <em>DISABLED</em> <code>TextBoxFor</code>, which is:</p>
  
  <pre><code>@Html.TextBoxFor(u =&gt; u.Visibilidade, new { disabled = "disabled", @readonly = "readonly" })
  </code></pre>
  
  <p>and</p>
  
  <pre><code>@Html.TextBoxFor(u =&gt; u.Visibilidade, new { disabled = "disabled" })
  </code></pre>
  
  <p>ie. using or not readonly property</p>
  
  <p>What is the difference, considering that a disabled field will not be changed any way?</p>
  
  <p>Thanks in advance</p>
