Try to set selected option at data source (SelectList) like that :

Dictionary<string, string> list = new Dictionary<string, string>();
list.Add("State 1", "1");
list.Add("State 2", "2");
list.Add("State 3", "3");
var selectList = new SelectList(list,
          "Value", "Key", 
          "2"); // selected item's value "State 2" is selected.
ViewData["States"] = selectList;

<%= Html.DropDownList("ddlStates", (SelectList)ViewData["States"]) %>
