Question

Good Morning,

I am using the editing scaffold. Here is the two bits of code:
Controller Code:

        public ActionResult Edit(int id)
        {
            var viewModel = new ListingManagerViewModel
            {
                Listing = AfvClassifiedsDB.Listings.Single(l => l.ListingID == id),
                Categories = AfvClassifiedsDB.Categories.ToList(),
            };

            return View(viewModel);
        }

        //
        // POST: /ListingManager/Edit/5

        [HttpPost]
        public ActionResult Edit(int id, FormCollection collection)
        {
            var listing = AfvClassifiedsDB.Listings.Single(l => l.ListingID == id);
            try
            {
                // Save the changes to Listing.

                UpdateModel(listing, "Listings");
                AfvClassifiedsDB.SaveChanges();

                return RedirectToAction("Index");
            }
            catch
            {
                // An error has occured so redisplay the form instead.

                var viewModel = new ListingManagerViewModel
                {
                    Listing = listing,
                    Categories = AfvClassifiedsDB.Categories.ToList(),
                };

                return View(viewModel);
            }
        }

View Code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<AfvClassifieds.ViewModels.ListingManagerViewModel>" %>
<asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server">
    Edit
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server">

    <h2>Edit</h2>

    <% using (Html.BeginForm()) {%>
        <%: Html.ValidationSummary(true) %>

        <fieldset>
            <legend>Fields</legend>

            <%: Html.EditorFor(model => Model.Listing, new { Categories = Model.Categories })%>

            <p>
                <input type="submit" value="Save" />
            </p>
        </fieldset>

    <% } %>

    <div>
        <%: Html.ActionLink("Back to List", "Index") %>
    </div>

</asp:Content>

This seems to work, but when you submit the form, the values aren’t changed. This has been created using the MVC Music Store as a guide. No errors, but the form values I create aren’t submitted.

Answer 1

Can you post the UpdateModel method?

However, it is clearly that you don’t update anything there. You didn’t do anything to the form collection FormCollection collection. the FormCollection is the actual form data that is inserted by user, so you should take all the values from it and save it in db.
