title: How to Create an Empty Html.DropDownlistFor & how to disable Html.TextBox
body: <p>I have the following code inside my asp.net mvc view:-</p>
  
  <pre><code>@Html.DropDownListFor(model =&gt; model.FirewallCustomer.CustomerVLANSID,null, null, null)
  @Html.ValidationMessageFor(model =&gt; model.FirewallCustomer.CustomerName)
  &lt;div&gt;&lt;span class="f"&gt;VLAN IP&lt;/span&gt; @Html.TextBox("VLANIP", new { disabled = "disabled"})&lt;/div&gt;
  </code></pre>
  
  <p>but the above code will raise an error on the DropDownListFor:-</p>
  
  <blockquote>
    <p>There is no ViewData item of type 'IEnumerable' that
    has the key 'FirewallCustomer.CustomerVLANSID'.</p>
  </blockquote>
  
  <p>and for the TexBox it will show the <code>disabled = "disabled"</code>  inside the textbox body, instead of disabling it. can anyone adivce on how to solve my dropdownlist &amp; my textbox problems???
  Thanks`</p>
