title: MVC Dropdown list value not being set
body: <p>I'm sure I am missing something obvious, but this is driving me nuts!  If I specify html options, the value of my dropdownlist doesn't set.</p>
  
  <p>In my controller, I retrieve the options for my dropdownlist with:</p>
  
  <pre>ViewData["Coordinator"] = new SelectList(userRepository.GetIdUserList(1), 
                            "ID",    "Signature",edCenter.Coordinator);</pre>
  
  <p>In my view I populate the dropdownlist with:</p>
  
  <pre>
  Html.DropDownList("Coordinator",(IEnumerable) ViewData["Coordinator"],
                     new {style="width:175px"})</pre>
  
  <p>The dropdown values are populated perfectly, but the value of the list isn't selected.</p>
  
  <p>However, if I just use:</p>
  
  <pre>Html.DropDownList("Coordinator");</pre>
  
  <p>Everything works fine.  </p>
  
  <p>What is going wrong??</p>
