ModelState.IsValid is false

I have an auto scaffold view

<h2>Create</h2>


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

    <div class="form-horizontal">
        <h4>Event</h4>
        <hr />
        @Html.ValidationSummary(true)

And the controller is 

   [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create(EventCreateViewModel eventVM)
    {
        if (ModelState.IsValid) // Always false
        {
            var @event = new Event
            {
                EventName = eventVM.EventName,
                ......
                CreateTime = DateTime.Now,
                CreatedBy = User.Identity.Name,
            };
            AddOrUpdateCategories(@event, eventVM.Categories);
            db.Events.Add(@event);
            db.SaveChanges();

            return RedirectToAction("Index");
        }

        return View(eventVM);
    }

It doesn't save the data. And the ModelState.IsValid is always false. There is no message show in the html page @Html.ValidationSummary(true). How to get the reason of the failure?

Add breakpoint to the line with "if (ModelState.IsValid)" Look into ModelState... there are 2 arrays - I think "Keys" and "Values". In Values array you can find what is wrong (is set to false) and in Keys you will find source of problem (look at the same index).

If you want to see all validation errors in validation summary, you should use it with false flag:

@Html.ValidationSummary(false)

@Html.ValidationSummary(true) means that all model property errors are suppressed from the summary. In order to see those errors, you have to add the individual validation messages:

@Html.ValidationMessageFor(m => m.YourModelProperty)
