asp.net MVC1.0 分页问题

[luyanvv]

我在Controller文件里面建一个FirstControler:

--这是我新建的ADO.NET 实体
NorthwindEntities1 db = new NorthwindEntities1();

public ActionResult f(int? page)
{
const int pageSize = 10;
var upcomingOrders = FindUpcomingOrders();
var paginatedOrders = new PaginatedList<Orders>(upcomingOrders, page ?? 0, pageSize);
return View(paginatedOrders);
}

public IQueryable<Orders> FindUpcomingOrders()
{
return from order in db.Orders
where order.OrderDate < DateTime.Now
orderby order.OrderDate
select order;
}

接着又建了一个类,是在同一个命名空间的:
public class PaginatedList<T> : List<T>
{
public int PageIndex { get; private set; }
public int PageSize { get; private set; }
public int TotalCount { get; private set; }
public int TotalPages { get; private set; }

public PaginatedList(IQueryable<T> source, int pageIndex, int pageSize)
{
PageIndex = PageIndex;
PageIndex = pageSize;
TotalCount = source.Count();
TotalPages = (int)Math.Ceiling(TotalCount / (double)PageSize);
this.AddRange(source.Skip(PageIndex * PageSize).Take(PageSize));
}

public bool HasPreviousPage
{
get { return (PageIndex > 0); }
}

public bool HasNextPage
{
get { return (PageIndex + 1 < TotalPages); }
}
}

接着,我又在View文件里面新建了一个f.aspx
把继承改为
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<MVC_First.Controllers.PaginatedList<Orders>>%>"
<table style="border:solid 1px #cccccc" width="100%">
<%
foreach (var m in ViewData.Model)
{
%>
<tr><td><%=m.OrderID %></td></tr>
<%
}
%>
</table>
<% if (Model.HasPreviousPage)//这个是PaginatedList的属性
{ %>
<%= Html.RouteLink("上一页","UpcomingDinners",new { page=(Model.PageIndex-1) }) %>
<% } %>
<% if (Model.HasNextPage)
{ %>
<%= Html.RouteLink("下一页","UpcomingDinners",new { page = (Model.PageIndex + 1) })%>
<% } %>

运行的时候,它就报要Orders没有using.
然后,我就把System.Web.Mvc.ViewPage<MVC_First.Controllers.PaginatedList<Orders>>%>换成
System.Web.Mvc.ViewPage<List<MVC_First.Models.Orders>>
它又报认不到HasPreviousPage属性,也是没有using
天啊.该怎么弄呀

[desegou]

把该用到得引用加上去

牛啊，MVC都搞上了。。。。。。。。。。。。。学习了.....

[Dream_Hunter_]

顶！学习！虽然还没接触过MVC...

[bjs007]

貌似楼主的代码是参照Scott的pdf版MVC教程写的！

[winner2050]

好端端的三层结构的ASP.net不用。

MVC 都写成了 ASP+ 了，何苦呢！

[luyanvv]

我前天才可以看MVC,就做几个例子,头都大了.

我不知道怎么给它加引用呀.天啊.该怎么办呀.

[bjs007]

Inherits="System.Web.Mvc.ViewPage <MVC_First.Controllers.PaginatedList <Orders>>
换成：Inherits="System.Web.Mvc.ViewPage <MVC_First.Controllers.PaginatedList <MVC_First.Models.Orders>>试试

[luyanvv]

[Quote=引用 10 楼 bjs007 的回复:]
Inherits="System.Web.Mvc.ViewPage <MVC_First.Controllers.PaginatedList <Orders>>
换成：Inherits="System.Web.Mvc.ViewPage <MVC_First.Controllers.PaginatedList <MVC_First.Models.Orders>>试试

那样是可以了,但是为什么没有数据显示呢.

[bjs007]

建议你在MOdels文件夹下新建个PaginatedList类，里面的代码
public class PaginatedList <T> : List <T>
{
public int PageIndex { get; private set; }
public int PageSize { get; private set; }
public int TotalCount { get; private set; }
public int TotalPages { get; private set; }

public PaginatedList(IQueryable <T> source, int pageIndex, int pageSize)
{
PageIndex = PageIndex;
PageIndex = pageSize;
TotalCount = source.Count();
TotalPages = (int)Math.Ceiling(TotalCount / (double)PageSize);
this.AddRange(source.Skip(PageIndex * PageSize).Take(PageSize));
}

public bool HasPreviousPage
{
get { return (PageIndex > 0); }
}

public bool HasNextPage
{
get { return (PageIndex + 1 < TotalPages); }
}
}

然后在FirstControler:这样写
public ActionResult f(int? page)
{
const int pageSize = 10;
var upcomingOrders = FindUpcomingOrders();
var paginatedOrders = new PaginatedList <Orders>(upcomingOrders, page ?? 0, pageSize);
//导入命名空间：using MVC_First.Models
return View(paginatedOrders);
}

Inherits="System.Web.Mvc.ViewPage <MVC_First.Controllers.PaginatedList <Orders>>
换成：Inherits="System.Web.Mvc.ViewPage <MVC_First.Models.PaginatedList <MVC_First.Models.Orders>>

看到太多的代码就晕呼呼~~~

up,,

[li_dao_hang_1989]

楼主厉害都搞mvc啦……
呵呵……
我也学习！

[sforiz]

学习、、、UP

[使我做你和平之子]

把Orders所在的命名空间加上：
<%@ Import Namespace = "。。。" %>

我试过了,这个是不行的.
改成这样就没问题
Inherits="System.Web.Mvc.ViewPage <MVC_First.Models.PaginatedList <MVC_First.Models.Orders>>

但是数据就是显示不出来呀.天啊.

[luyanvv]

谢谢各位,现在没有出现那个认不到命名空间的问题啦.

可能是我写的SQL语句的问题吧,我检查下,如果真的不行,我再另外开贴.
