Answer 1

+1 A:

<%= Html.DropDownList() %> has about 8 overloads that you can use. You'll need to map your enumeration into an IEnumerable<SelectListItem> to pass to it though. Something like this:

var names = Enum.GetNames(typeof(MyEnum));
List<SelectListItem> items = new List<SelectListItem>();
foreach (var s in names)
{
   items.Add(new SelectListItem() { Text = s, 
                                    Value = s,
                                    Selected = (s == "SelectedValue") };
}

Personally, if I were doing it this way I'd use LINQ rather than creating a list and then populating it. Transforming a sequence of one thing into a sequence of something else is exactly what LINQ is good at. var items = Enum.GetNames(typeof(MyEnum)).Select(n => new SelectListItem() { Text=n, Value=n, Selected = (n == "SelectedValue") });

Answer 2

+1 A:

The FluentHtml library from MVC Contrib has built-in support for generating select boxes from enumerations.

<%= this.Select("example")
        .Options<System.IO.FileOptions>()
        .Selected(System.IO.FileOptions.Asynchronous) %>

This outputs:

<select id="example" name="example">
    <option value="0">None</option>
    <option value="16384">Encrypted</option>
    <option value="67108864">DeleteOnClose</option>
    <option value="134217728">SequentialScan</option>
    <option value="268435456">RandomAccess</option>
    <option selected="selected" value="1073741824">Asynchronous</option>
    <option value="-2147483648">WriteThrough</option>
</select>
