Sample solution

Demo site

Very simple Controller

    public JsonResult A1(Guid? id)
    {
        var model = new MyModel { Id = g2, Id2 = g2, Name = "A1" };

        return new JsonResult
        {
            Data = new
            {
                html = this.RenderPartialView("A1", model),
            },
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
    }

    public JsonResult A2(Guid? id)
    {
        ModelState.Clear();
        var model = new MyModel { Id = g2, Id2 = g2, Name = "A2" };

        return new JsonResult
        {
            Data = new
            {
                html = this.RenderPartialView("A1", model),
            },
            JsonRequestBehavior = JsonRequestBehavior.AllowGet
        };
    }

Very simple View with two buttons and script

    <p><a class="btn btn-default" href="#" onclick="F1(1)">NO ModelState.Clear()</a></p>
    <p><a class="btn btn-default" href="#" onclick="F1(2)">ModelState.Clear()</a></p>

function F1(a) {
    $.ajax({
        type: 'GET',
        url: '@Url.Content("~/Home/A")' + a,
        data: {
            id: '@ModelBug.Controllers.HomeController.g1'
        },
        dataType: 'json',
        beforeSend: function (xhr) {
        },
        success: function (data) {
            $("#col" + a).append('<div class="row"><div class="col-md-12">' + data.html + '</div></div>');
        },
        error: function () {

        }
    });
}

Very simple rendered View

<div>Model.Id = @Model.Id</div>
<div>TextBoxFor(model => model.Id) = @Html.TextBoxFor(model => model.Id)</div>
<div>TextBoxFor(model => Model.Id) = @Html.TextBoxFor(model => Model.Id)</div>
<div></div>

<div>Model.Id2 = @Model.Id2</div>
<div>TextBoxFor(model => model.Id2) = @Html.TextBoxFor(model => model.Id2)</div>
<div>TextBoxFor(model => Model.Id2) = @Html.TextBoxFor(model => Model.Id2)</div>
<div></div>

<div>Model.Name = @Model.Name</div>
<div>TextBoxFor(model => model.Name) = @Html.TextBoxFor(model => model.Name)</div>
<div>TextBoxFor(model => Model.Name) = @Html.TextBoxFor(model => Model.Name)</div>
<div></div>
<div></div>

In result view in TextBoxFor(model => Model.Id) without ModelState.Clear()

show 4a01aadd-c61a-4524-95f6-e88a665c0745 (from param (Guid? id))

must be d2afb9a8-fb43-4237-9f34-abc7e5b59a41** (from public static Guid g2)

Main problem

Why value in TextBoxFor() from param id not from model.Id ?

P.S. This problem get in big project where model get from DataBase but in view model.Id is different from Database, model.Id = param of query.
