  1. <div id="pageNav" class="pageinator">
  2.   @Html.ShowPageNavigate((int)ViewData["pageindex"], (int)ViewBag.pageSize, (int)ViewBag.totalCount);

控制器

  1. shopEntities shop = new shopEntities();
  2.   public ActionResult Index()
  3.   {
  4.    //IQueryable<tbl_order> order = (from a in shop.tbl_order select a).OrderBy(a=>a.id).Skip(10).Take(10);

  8.    int pageSize = Request["pageSize"] == null ? 10 : int.Parse(Request["pageSize"]);
  9.    int totalCount = 0;
  10.    //给前台传递 分页的参数数据
  11.    ViewData["pageIndex"] = pageIndex;
  12.    //ViewData["pageSize"] = pageSize;
  13.    ViewBag.pageSize = pageSize;
  14.    //总条数
  15.    totalCount = shop.tbl_order.Count();
