I was struggling with a similar problem yesterday so if you are still getting the same result there is one more thing to consider. The DropDownList sometimes ignores the selected value of your SelectList, it's annoying but what it does is try to get the selected value from the ModelState, ViewData and Model by using the field name as a key. In your case you are storing the list in ViewData["Coordinator"], the key has the same name as the DropDown. Try this:

ViewData["CoordinatorList"] = new SelectList(userRepository.GetIdUserList(1), 
                          "ID",    "Signature",edCenter.Coordinator);

ViewData["Coordinator"] = dCenter.Coordinator;

Then in the view:

    <%=Html.DropDownList("Coordinator",((SelectList)ViewData["CoordinatorList"]).AsEnumerable(),
 new {style="width:175px"}) %>

If you want to see what's going on behind the curtains open reflector (or get the MVC source) and browse this method: System.Web.Mvc.Html.SelectExtensions.SelectInternal()
