Adding Multiple Static options to a Drop-Down in ASP.NETMVC

Question

Hi,

I want to add two default options to my dropdowns in asp.net MVC using the html helper class, they are "--Please Select--" and "--Other--".

I can add one static option using

<%= Html.DropDownList("ddlserviceGroup",
    (IEnumerable<SelectListItem>)ViewData["ServiceGroups"], "--Select Item--")%>

But i need to add two options and can't seem to figure it using the HTML helper class

The existing helper doesn't allow this. I'd suggest adding the options in the controller or perhaps writing your own extension method.

 var serviceGroups = db.Groups
                       .Select( g => new SelectListItem
                                     {
                                          Text = g.Name,
                                          Value = g.ID
                                     })
                       .ToList();
// prepend to list
serviceGroups.Insert( 0, new SelectListItem
                         {
                             Text = "--Select Item --",
                             Value = string.Empty
                         } );
// add at end
serviceGroups.Add( new SelectListItem
                   {
                       Text = "-- Other -- ",
                       Value = ????
                   });

ViewData["ServiceGroups"] = serviceGroups;

In View

<%=
    Html.DropDownList("ddlserviceGroup",
                      (IEnumerable<SelectListItem>)ViewData["ServiceGroups"]
 %>
