For MVC v5.1 use Html.EnumDropDownListFor
@Html.EnumDropDownListFor(
x => x.YourEnumField,
"Select My Type",
new { @class = "form-control" })
For MVC v5 use EnumHelper
@Html.DropDownList("MyType",
EnumHelper.GetSelectList(typeof(MyType)) ,
"Select My Type",
new { @class = "form-control" })
For MVC 5 and lower
I rolled Rune's answer into an extension method:
namespace MyApp.Common
{
public static class MyExtensions{
public static SelectList ToSelectList<TEnum>(this TEnum enumObj)
where TEnum : struct, IComparable, IFormattable, IConvertible
{
var values = from TEnum e in Enum.GetValues(typeof(TEnum))
select new { Id = e, Name = e.ToString() };
return new SelectList(values, "Id", "Name", enumObj);
}
}
}
This allows you to write:
ViewData["taskStatus"] = task.Status.ToSelectList();
by using MyApp.Common
Here's what I came up with, and it's working for me. I added the following method(s) to my controller base class. (You can always make these static methods somewhere else that accept a controller as a parameter I suppose)
MVC2 .ascx style
protected string RenderViewToString<T>(string viewPath, T model) {
ViewData.Model = model;
using (var writer = new StringWriter()) {
var view = new WebFormView(ControllerContext, viewPath);
var vdd = new ViewDataDictionary<T>(model);
var viewCxt = new ViewContext(ControllerContext, view, vdd,
new TempDataDictionary(), writer);
viewCxt.View.Render(viewCxt, writer);
return writer.ToString();
}
}
Razor .cshtml style
public string RenderRazorViewToString(string viewName, object model)
{
ViewData.Model = model;
using (var sw = new StringWriter())
{
var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
viewName);
var viewContext = new ViewContext(ControllerContext, viewResult.View,
ViewData, TempData, sw);
viewResult.View.Render(viewContext, sw);
viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
return sw.GetStringBuilder().ToString();
}
}
Edit: added Razor code.

I know this is an old post, but I have a good blog post on how to impliment a custom provider for Validation in MVC 2.0. http://www.bitsinmyhead.com/2010/09/asp-net-mvc-2-0-and-its-validation%E2%80%A6-using-a-custom-provider/
