title: Setting a default selected value in DropDownList in MVC3
body: <p>In MVC3 I have this code at my controller. It retrieves a List of IDs\Names from Installation table and creates a ViewBag</p>
  
  <pre><code>var vs = dba.Installation.OrderBy(q =&gt; q.InstName).ToList();
  ViewBag.Vessels = new SelectList(vs, "InstId", "InstName");
  </code></pre>
  
  <p>Now, at my view. I want to render the list in a dropdown list. I used the Html helper that works fine...</p>
  
  <pre><code>@Html.DropDownList("InstId",(SelectList)ViewBag.Vessels, "- Select one -")
  </code></pre>
  
  <p>I need to set first item in the ViewBag List as a default selected value, instead of "- Select one -" text. </p>
  
  <p>How can I do it?  </p>
  
  <p>Thanks in advance!</p>
