title: ASP.NET MVC Select Option Value of SelectList
body: <p>I am rendering a dropdown list. </p>
  
  <pre><code>ViewBag.Categories = new SelectList(db.HelpCategories, "ID", "Name");
  </code></pre>
  
  <p>In my view I call it like this:</p>
  
  <pre><code>Categories: @Html.DropDownList("Categories", (SelectList)ViewBag.Categories, "All")
  </code></pre>
  
  <p>For which I get select values like this.</p>
  
  <pre><code>&lt;select id="Categories" name="Categories"&gt;
     &lt;option value=""&gt;All&lt;/option&gt;
     &lt;option value="1"&gt;Dėl Krepšelių&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>I really need to set the value of "All" to 0. Can't figure out a way to do it. Found a tutorial that it's done with SelectListItem, but that doesn't fit my code. 
  Any help is really appreciated, thank you.</p>
