title: Add value to dynamically populated list c#
body: <p>I'm constructing a web page based on ASN.NET MVC3 with Razor templates and Entity. The task is to populate a @Html.DropDownList from the database, so far so good but now I want to insert a static value in the DropDownList.</p>
  
  <p>The code looks as follows</p>
  
  <p>The create method</p>
  
  <pre><code>public ActionResult Create()
  {
      var parents = db.Organizations.OrderBy(o =&gt; o.Title).ToList();
      var organization = new Organization();
      return View(organization);
  } 
  </code></pre>
  
  <p>Extract from the Razor template</p>
  
  <pre><code>&lt;div class="editor-field"&gt;
      @Html.DropDownList("ParentGuid",
      new SelectList(ViewBag.Organizations as System.Collections.IEnumerable,
      "ParentGuid", "Title", Model.ParentGuid))
  &lt;/div&gt;
  </code></pre>
  
  <p>So, the above code works but Im stuck in figuring out how to insert an empty row in the dropdown.</p>
