急MVC3 数据分页

Question

我在model里定义了一个
 public class pageInfo
    {
        public int pageSize { get; set; }
        public int pageCount { get; set; }
    }
controller:
 public ActionResult Index(int? p)
        {
            if (!p.HasValue) p = 1;
            pageInfo page = new pageInfo();
            page.pageSize = 3;
            page.pageCount = BookBll.PageRecodCount();
            DataTable dt = BookBll.dtPage(page.pageSize,p);
            return View(dt);
        }
在view中怎么用model时原pageSize,pageCount呢？
@Html.Pager("p",pageSize,pageCount)

Answer 1

在view中怎么用model时原pageSize,pageCount呢？
这句话怎么就看不懂。

Answer 2

我的意思是写
@Html.Pager("p",Model.pageSize,Model.pageCount)
时点.后面的不出来

Answer 3

MvcPager

@[email protected]("p", 3,11)
这个11为记录的总条数，怎么写让一个变量把11给换掉呢

Answer 6

你要想办法把前台的 分页属性，在后头Controllers里可以赋值。做到这一步，可以开放参数，叫前台调用时设置。

Answer 7

我没有办法把数据的总数从前台给controller啊

Answer 8

我想通过这个取：@ViewBag.size /  
@ViewBag.count
提示错误：静态方法不能用动态参数。

Answer 9

你弄了viewbag了那就往里面填啊，还用建一个什么pageInfo类干什么

Answer 10

viewbag不给力，我就换了pageinfo 类
