   {

    @Html.AntiForgeryToken()
    @Html.ValidationSummary(true)

    <fieldset>

        <ol>
            <li>
                @Html.LabelFor(m => m.Item2.EmailId)
                @Html.TextBoxFor(m => m.Item2.EmailId, new { @id = "txt_fg_pwd_EmailID" })
                @Html.ValidationMessageFor(m => m.Item2.EmailId)

            </li>
            <li>

                <input type="submit" value="Reset Password" />
            </li>
        </ol>
    </fieldset>
}

my post method is

    [HttpPost]
    public ActionResult Login(LoginModel LoginUser , string returnUrl)
    {   


        if (LoginUser.IsValid)
        {

            SetAuthenticationCookie(LoginUser, LoginUser.RememberMe);

            return RedirectToLocal(returnUrl);

        }
        else
        {
            ModelState.AddModelError("", "Incorrect user name or password .");
            return View(LoginUser);
        }


    }

`

Any changes need to to view or post method

Answer 1

Try like this:

[HttpPost]
public ActionResult Login([Bind(Prefix = "Item1")] LoginModel loginUser, string returnUrl)
{
    ...
}

Since your values are prefixed with Item1 you should indicate that to the model binder. Of course the same stands true for your ForgotPassword action:

[HttpPost]
public ActionResult ForgotPassword([Bind(Prefix = "Item2")] ForgotPassword model)
{
    ...
}
