My problem I am binding the data to the Dropdownlist from the database and it works fine up to that point. When i am submitting the form it automatically returning null value and finally ModelState.IsValid is also returning false.

While searching from the internet I have given the code:

var errors = ModelState.Values.SelectMany(x => x.Errors);

I will briefly describe my problem

Please help me to solve this problem

What I have tried:

My Controller:

[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public ActionResult EmployeeLeave(EmployeeLeaveViewModel objLeave)
{
    string typeOfLeaveText = Request.Form["HiddenText"].ToString();
    if (string.IsNullOrEmpty(objLeave.HiddenText))
    {
        ModelState.AddModelError("Error", "Leave type cannot be default value");
    }
}

My View:

<div class="form-group">
    @Html.DropDownListFor(m => m.HiddenText, Model.Nature, "-Please Select-")
    @Html.HiddenFor(m => m.HiddenText)
    @Html.ValidationMessageFor(m => m.Nature, "", new { @style = "color:red" })
</div>

My Model:

public string HiddenText { get; set; }

[Required(ErrorMessage = "Type of Leave field is required")]
[Display(Name = "Type of Leave")]
public List<SelectListItem> NatureofLeave { get; set; }

Is that your full view? Where is the code to send it to the Controller? Is it with a 'form' tag and a button? JavaScript?

Your drop-down list is posting to the HiddenText field. It should presumably be posting to the NatureOfLeave field instead:

@Html.DropDownListFor(m => m.NatureOfLeave, Model.Nature, "-Please Select-")

Also, your model seems to be confusing the list of options with the selected option:

// The value selected in the list:
[Required(ErrorMessage = "Type of Leave field is required")]
[Display(Name = "Type of Leave")]
public string NatureOfLeave { get; set; }

// The list of options to pick from:
public List<SelectListItem> Nature { get; set; }
