  enum args in controller action methods?

  Jun 26, 2009 03:08 PM|LINK

  Is it possible use an enum argument in a controller action method?   How would javascript represent an enum arg value when calling a controller action?

  
  

  
  

  thanks!

   I've done it as a member property of an object that is getting model bound, so the DMB can definitely do it that way (in that case, I represented the enum as a dropdownlist).  NOt sure if it would work on its own.  going from JS might be more complex; I'll have to think about it.

  Yes, it is possible. You can submit either the integer value or the string name of the enum value. A quick experiment verifies this. For example, in HomeController.cs write this.

  public class HomeController : Controller {
          public ActionResult Index() {
              return View();
          }
  
  
          [AcceptVerbs(HttpVerbs.Post)]
          public ActionResult Index(MyEnum value) {
              ViewData["Message"] = value.ToString();
  
  
              return View();
          }
      }
  
  
      public enum MyEnum {
          Foo,
          Bar,
          Baz
      }

  
  Then in Index.aspx include the form:

      <% using (Html.BeginForm()) { %>
          <%= Html.TextBox("value") %>
          <input type="submit" />
      <% } %>

  And try submitting the value 0 then try submitting Bar and you'll see they both work.
