Question

I’m using Scaffolding in ASP.Net, I’ve a Model called “Page” which has attributes as follows

public class Page
{
    private DateTime _Created_at = DateTime.Now;
    private bool _IsActive = true;

    public int ID { get; set; }

    public string Code { get; set; }

    [Required]
    [DisplayName("Parent Code")]
    public string ParentCode { get; set; }

    [Required]
    public string Title { get; set; }

    ************
} 

Here, During Create Method, I’m updating Code attributes as follows

        public ActionResult Create(Page page)
        {
            if (ModelState.IsValid)
            {
                page.Code = page.Url.Replace(" ", string.Empty);
                page.IsActive = true;
                db.Pages.Add(page);

                db.SaveChanges();

                return RedirectToAction("Details", new { id = page.ID });
            }

            return View(page);
        }

Now, Problem is, I don’t want this Code value change during Update method, I’m not included it in Edit form. But still it’s updating ‘NULL’ value if I update.

I tried [Bind(Exclude = "Code")] for Page class, But no use.

You need a hidden field for code in your edit view. Use @Html.HiddenFor(model => model.Code).
