How to make upload work in asp mvc 2?

I have used the code provided in this link for the upload-handling:

http://towardsnext.wordpress.com/2009/04/17/file-upload-in-aspnet-mvc/

But this isn't working for me. (when I click the "Upload file" button when I'm running the site nothing happens.) I have edited my view like this

<script type="text/javascript">
    $(function () {
        $("#dialog").dialog({bgiframe: true, height: 140, modal: true, autoOpen: false, resizable: false}) });
</script>

and also

<div id="dialog" title="Upload files">
                    <% using (Html.BeginForm("Upload", "Upload", FormMethod.Post, new { enctype = "multipart/form-data", id = item.OrderId })){%>
                        <p><input type="file" id="fileUpload" name="fileUpload" size="23"/> </p>
                        <p><input type="submit" value="Upload file" /></p>
                    <% } %>
                </div>
                <a href="#" onclick="jQuery('#dialog').dialog('open'); return false">Upload开发者_C百科 File</a>

My Upload-function (defined in UploadController) looks like this:

using System;

using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using System.Web.Mvc.Ajax; using System.IO; using SiteVCM.Models;

namespace SiteVCM.Controllers { public class FileDescription { public string Name { get; set; } public string WebPath { get; set; } public long Size { get; set; } public DateTime DateCreated { get; set; } }

public class UploadController : Controller
{
    StoreEntities storeDB = new StoreEntities();

    //
    // GET: /Upload/

    FileRepository fileRepository = new FileRepository();

    //public ActionResult Index()
    //{
    //    return View(fileRepository.GetAllFileDescription());
    //}

    public ActionResult Upload(int id)
    {
        foreach (string inputTagName in Request.Files)
        {
            HttpPostedFileBase file = Request.Files[inputTagName];
            if (file.ContentLength > 0)
            {
                string filePath = Path.Combine(HttpContext.Server.MapPath("../Samples")
                    , Path.GetFileName(file.FileName));
                file.SaveAs(filePath);

                var order = storeDB.Orders.Single(c => c.OrderId == id);
                order.Url = filePath;
                storeDB.SaveChanges();
            }

        }

        return RedirectToAction("Index", "Status", new { id = 0 });
    }

}

and the FileRepository.cs file is the same except for the namespacing and the place to ut the files in.

The JQuery Dialog box pops up like it should but when I click on the "Upload File" button nothing happens.

The view this code is in belongs to antoher controller then the one my Upload-function is defined in.

Please help me I've been looking for hours to fix this and I freaking me out.

Thanks in advance!!

This works for sure

<% using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
  new { enctype = "multipart/form-data" })){%>
     <input type="file" id="fileUpload" name="fileUpload"/>
     <input type="submit" value="Upload file" />
<% } %>

public ActionResult Upload(HttpPostedFileBase fileUpload)
{
  //fileUpload == posted file
}
