Mandatory selection for dropdown list in asp.net MVC 2

I have a strongly typed view populated from viewmodel that has dropdown list.

 <%= Html.DropDownList("ID", Model.custList, "--select--")%>
  <%= Html.ValidationMessage("ID")%>

Which passes id to controller

public ActionResult Submit((int? ID)



I want to make dropdown mandatory so user must select an option
<%= Html.DropDownList("ID", Model.customereList, "--select--")%>

Open in new window

If it's mandatory you could just take out the "--select--" option and default to the first option in the list instead.

Hi

No I need the select option as this is a request from the client
