Hello,

My Creating View is not saving record to database, don't know what is the error, bcoz its showing no error but only invalidate Modelstate.

Controller code is below:

HTML
// GET: Discounts/Create
       public ActionResult Create()
       {
           ViewBag.InstitutionID = new SelectList(db.tblInstitutes, "InstitutionID", "Institution");
           ViewBag.FeeTypeID = new SelectList(db.tblFeeTypes, "FeeTypeID", "FeeType");
           return View();
       }

       // POST: Discounts/Create
       // To protect from overposting attacks, please enable the specific properties you want to bind to, for
       // more details see http://go.microsoft.com/fwlink/?LinkId=317598.
       [HttpPost]
       [ValidateAntiForgeryToken]
       public ActionResult Create(Discount discount)
       {
           if (ModelState.IsValid)
           {
               db.Discounts.Add(discount);
               db.SaveChanges();
               return RedirectToAction("Index");
           }
           ViewBag.InstitutionID = new SelectList(db.tblInstitutes, "InstitutionID", "Institution");
           ViewBag.FeeTypeID = new SelectList(db.tblFeeTypes, "FeeTypeID", "FeeType");
           return View(discount);
       }


What I have tried:

View is here:

HTML
@model SchoolMVC.Models.Database.Discount

@{
    ViewBag.Title = "Create";
}

<h2>Create</h2>

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">

If your model state is invalid, the values posted to the server do not pass the validation rules you have defined on your model.

Add a validation summary to the top of your form to view the list of validation errors:
Razor
@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    @Html.ValidationSummary()
    ...
