在返回视图中返回json值时未传递值

Question

我有一个视图，我想以这种方式返回json值，但数据未返回。当删除return视图并且仅传递return json（）时，数据显示在grid中。但格式不正确意味着数据显示不像jqgrid那样正确显示控制台窗口。我正在共享操作结果和json函数以及正在使用的Grid。

请仔细检查一下，然后告诉我什么是解决方案。如何在返回视图中返回json值。

Action

    public ActionResult Ownership_Detail(string MemberShipID)
                {
                    ViewBag.id = MemberShipID;
                    Ownership_D(MemberShipID);
                    return View(Json(ViewBag.objOwnershipDetail, JsonRequestBehavior.AllowGet));


                }



json Function
     public JsonResult Ownership_D(string MemberShipID)
            {
                List<OwnerShip> OwnerShipDetail = new List<OwnerShip>();
