Why hidden field value not getting correctly on controller side on form submit in MVC?

Question

I used MVC 5 and MongoDB, I am trying to get Hidden Field value (ObjectId) in controller on form submit but getting default value(000000000000000000000000) instead of actual value (5af58cedf86bc82ab0e0f825).

Here field type is ObjectId(MongoDB.Bson Type)

Please help me I am new in MongoDB. Thanks in Advance

@using (Html.BeginForm()) {
<div class="container ">
  <div class="row">
    @Html.HiddenFor(m => m.Employee._id, new { @Value = ObjectId.Parse(Model.Employee._id.ToString()) });
    <div class="col-md-12">
      <h3 class="text-center" style="margin: 25px 0;">
        Employee Registration Form
      </h3>
      <h4 class="text-center" style="margin: 25px 0">
        <span style="color:red">
                            @if (TempData["ErrorMessage"] != null)
                            {
                                @TempData["ErrorMessage"]
                            }
                        </span>
        <span span style="color:forestgreen">
                            @if (TempData["SuccessMessage"] != null)
                            {

My best guess is that you are messing something up with the Events. You might try to get values too early (before they have been retrieved from the postback). It is rather important that you fully understand the ASP.Net Page Lifecycle: https://msdn.microsoft.com/en-us/library/ms178472.aspx — Christopher, May 14 '18 at 06:33
You will need to create a custom ModelBinder for BSON types (the `DefaultModelBinder` does not know how to convert you value to an `ObjectId` - refer [this answer](https://stackoverflow.com/questions/3143254/how-to-pass-objectid-from-mongodb-in-mvc-net) for examples — , May 14 '18 at 06:36
