  Drop Down List NOT from datasource

  Jun 19, 2008 08:35 PM|LINK

  How do I create a New SelectList from a list of values and have a selected value from my database chosen.  For instance a list of states, I don't want that in the database, but i want my users to chose from the list?

  MVC DropDownList

   The data does not have to come from a database. You can use any enumerable type like a list or an array.

  <%=Html.DropDownList("States",new SelectList(new List<string>{"NSW", "Vic", "Tas"},"Vic")) %>

  Thanks Paul, that would work for me in a way but I guess I should have been a bit clearer.  Say I want to display the full state name and have the value be the abbreviation, any ideas on how to do that?

  The easiest way is to just code the html tags

  <select name="states">
     <option value="NSW">New South Wales</option>
     <option value="Qld" selected="selected">Queensland</option>
     <option value="Vic">Victoria</option>
  </select>

   the alternative could be something like

  <% var states = new[]{
         new {abbrev="Vic", full="Victoria"},
         new {abbrev="NSW", full="New South Wales"},
        new {abbrev="Qld", full="Queensland"}
     }; %>
  <%=Html.DropDownList("States",new SelectList(states, "abbrev", "full", "NSW")) %>

   Hope that helps

  If you don't want to write the HTML you can do something like this
  
  Controller:
  Dictionary<string,string> states = new Dictionary<string,string>();
  states.Add("NY", "New York");
  states.Add("PA", "Pennsylvania");
  ....
  ViewData["States"] = new SelectList(states, "Key", "Value", "NY");
  return View("Index");
  
  ////
  
  Page.aspx
  <%= Html.DropDownList("States") %>
