Can I update ModelState.IsValid?

In my controller I have the following code:

    [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(AdEntry adentry)
    {

            adentry.adDate = DateTime.Now;
            adentry.adExpirationDate = DateTime.Now.AddDays(32);
            adentry.adConfirmationID = rKeyGen(8);

            if (ModelState.IsValid)
            {
                db.Items.Add(adentry);
                db.SaveChanges();
                TempData["Summary"] = adentry;
                return RedirectToAction("Index");
            }

        return View(adentry);
    }

In my Model I have this property:

   [Required(ErrorMessage = "Confirmation Id is Required.")]
    [StringLength(8, ErrorMessage = "{0} is too long.")]
    public virtual String adConfirmationID { get; set; }

When I try to create a new Item ModelState.IsValid = false. The error I get is that Confiramtion Id is Required. I am setting the adConfirmationID = to a value right above the check. How can I get this check to pass?

There are Two ways to handle this issue one is you remove the updated/invalid field from ModelState by this

ModelState.Remove("foo");

or you have to pass the value to controller from View by using the hidden field

 <input type="hidden" asp-for="foo"/>

Try this instead:

ModelState.Remove("adConfirmationID")

Place this code before checking ModelState.IsValid

This will fix your issue.
