Try to use after the changes

public ActionResult Index()
        {
ViewBag.Products = new SelectList(storeDb.Products, "ProductId", "Name","Put your selected value here");
 return View();
        }

Replace your value instead of this "Put your selected value here"
In view

@Html.DropDownList("Products", ViewBag.Products as SelectList, "Select Products", new { style = "width:200px" })

something this way

For the dropdown selection see the following code

<script type="text/javascript">
    $(document).ready(function () {
        $("#Products").change(function () {
            var url = "/ControlerName/GetProductDetails";
            var Products = $("#Products").val();
            $.ajax({
                url: url,
                type: 'post',
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                data: { id: Products },
                success: function (data) {
                    debugger;
                    $('#txtPrice').text(data.d);
                    //It's hope so data.d if not putt debugger and see where is the value 
                },
                error: function () { alert('something bad happened'); } 
            }); 
        });
    });

</script>

Change Url controller name as per your given name
and see It's hope so data.d if not putt debugger and see where is the value
