<pre>@foreach (var item in Model) {
    <tr data-productid="@item.Id">
        <td>
            @Html.DisplayFor(modelItem => item.ProductName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.ProductPrice, new { @id = "check" })

        $('.ddlStatus').change(function () {
            var val = $(this).val();
            var productId = $(this).parent('td').parent('tr').attr('data-productid')
            ChangeDis(val, productId);
        });
        function ChangeDis(val, productId) {
           
            $.ajax({
                url: '/Products/GetDis',

                    discount: val,

If you want to submit the value with your form, then you need to add a hidden field:

<label>Discount: <span id="lblDiscountAmount"></span></label>
<input type="hidden" name="DiscountAmount" id="DiscountAmount" />

JavaScript

success: function (data) {
    $('#lblDiscountAmount').text(data);
    $('#DiscountAmount').val(data);
}

If you want to pass it via an action link, then you'll need to identify those links, and pass the discount amount via the URL:

@Html.ActionLink("Edit", "Edit", new { id = item.Id }, new { @class = "--js-pass-discount" }) |
@Html.ActionLink("Details", "Details", new { id = item.Id }, new { @class = "--js-pass-discount" }) |
@Html.ActionLink("Delete", "Delete", new { id = item.Id })

JavaScript

$(document).on("click", "a.--js-pass-discount", function(e){
    var discountAmount = $('#lblDiscountAmount').text();
    if (!discountAmount) { return; }
    
    var url = this.href;
    var i = url.indexOf('?');
    url = url + (-1 === i ? '?' : '&') + 'discountAmount=' + encodeURIComponent(discountAmount);
    window.location.href = url;

    e.preventDefault();
});
