title: @Html.DropDownListFor does not set default selected value
body: <p>Can´t figure out why can´t set a default value here to be displayed:</p>
  
  <pre><code>@Html.DropDownListFor(m =&gt; m.storeLocations, new SelectList(Model.storeLocations, "id",
  "caminhoRepositorio", Model.idArmazenamento), new { @class = "largeField" })
  </code></pre>
  
  <p>The dropdown had the folowing configuration:</p>
  
  <pre><code> &lt;select class="largeField" id="storeLocations" name="storeLocations"&gt;
        &lt;option value="2"&gt;c:/item1&lt;/option&gt;
        &lt;option value="3"&gt;d:/item2&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>as a object "Model.idArmazenamento" I´ve already tried with int and string ("2" ou 2).
  Can´t get a default value selected </p>
