title: DropDownList mvc3 selected value doesn't work
body: <p>I got a question concerning a DropDownList with a selected value.</p>
  
  <pre><code>    @Html.DropDownListFor(m =&gt; m.weekForEachDayService[6].serviceId, new SelectList    (ViewBag.DayService, "Value", "Text"))
  </code></pre>
  
  <p>As you can see I have a service that is related to a week with a table weekForEachService.</p>
  
  <p>When I run this it never uses the serviceId inside the SelectList.</p>
  
  <pre><code>    @Html.DropDownListFor(m =&gt; m.weekForEachDayService[6].serviceId, new SelectList    (ViewBag.DayService, "Value", "Text",m =&gt; m.weekForEachDayService[6].serviceId))
  </code></pre>
  
  <p>I also tried something like this but then I get the Error message cannot convert type lambda to object. Usually when I use a DropDownList it automatically selects the correct value, but with this related table I think it's necessary to put the selected value in the list.</p>
  
  <p>Thanks you for helping</p>
