过滤 MVC 时分页中断

Question

我正在尝试让分页与多个搜索和排序顺序一起使用。当我进行搜索时，返回的第一页是结果集的正确页面，但是当我使用分页按钮选择下一页时，我的搜索不再考虑，我得到了所有结果。

我的控制器如下所示：

public ActionResult Index(string sortOrder, string searchString, string currentFilter, int? page, string Site, string Name, string Acct, string City, string State, string Address, string Status, string Type)
    {
        ViewBag.CurrentSort = sortOrder;
        ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
        ViewBag.AddressSortParm = sortOrder == "Address" ? "addr_desc" : "Address";
        ViewBag.SiteSortParm = sortOrder == "Site" ? "site_desc" : "Site";
        ViewBag.CitySortParm = sortOrder == "City" ? "city_desc" : "City";
        ViewBag.StateSortParm = sortOrder == "State" ? "state_desc" : "State";

        if (searchString != null || Site != null || Name != null || Acct != null || City != null || State != null || Address != null)
        {
            page = 1;
        }
        else
        {
            searchString = currentFilter;
        }

        ViewBag.CurrentFilter = searchString;

        var geocodes = from s in db.CFN_Geocodes select s;

        if (!String.IsNullOrEmpty(Name))
        {
            geocodes = geocodes.Where(s => s.NAME.Contains(Name));
        }

        if (!String.IsNullOrEmpty(Site))
        {
            geocodes = geocodes.Where(s => s.CFN_SITE.Contains(Site));
        }

        if (!String.IsNullOrEmpty(Address))
        {
            geocodes = geocodes.Where(s => s.STREET1.Contains(Address));
        }

        if (!String.IsNullOrEmpty(City))
        {
            geocodes = geocodes.Where(s => s.CITY.Contains(City));
        }

        if (!String.IsNullOrEmpty(State))
        {
            geocodes = geocodes.Where(s => s.STATE_CODE.Contains(State));
        }

        if (!String.IsNullOrEmpty(Acct))
        {
            geocodes = geocodes.Where(s => s.AccountNumber.Contains(Acct));
        }

        if (!String.IsNullOrEmpty(Status))
        {
            geocodes = geocodes.Where(s => s.Status.ToString().Contains(Status));
        }

        if (!String.IsNullOrEmpty(Type))
        {
            geocodes = geocodes.Where(s => s.SiteType.Contains(Type));
        }

        switch (sortOrder)
        {
            case "name_desc":
                geocodes = geocodes.OrderByDescending(s => s.NAME);
                break;
            case "Address":
                geocodes = geocodes.OrderBy(s => s.STREET1);
                break;
            case "addr_desc":
                geocodes = geocodes.OrderByDescending(s => s.STREET1);
                break;
            case "Site":
                geocodes = geocodes.OrderBy(s => s.CFN_SITE);
                break;
            case "site_desc":
                geocodes = geocodes.OrderByDescending(s => s.CFN_SITE);
                break;
            case "City":
                geocodes = geocodes.OrderBy(s => s.CITY);
                break;
            case "city_desc":
                geocodes = geocodes.OrderByDescending(s => s.CITY);
                break;
            case "State":
                geocodes = geocodes.OrderBy(s => s.STATE_CODE);
                break;
            case "state_desc":
                geocodes = geocodes.OrderByDescending(s => s.STATE_CODE);
                break;

            default:
                geocodes = geocodes.OrderBy(s => s.NAME);
                break;
        }
        int pageSize = 20;
        int pageNumber = (page ?? 1);
        return View(geocodes.ToPagedList(pageNumber, pageSize));
    }

我的观点是这样的：

 @model PagedList.IPagedList<Intranet.Models.CardlockSiteMgr.CFN_Geocodes>
@using PagedList.Mvc

<link href="~/Content/PagedList.css" rel="stylesheet" type="text/css" />

@{
    ViewBag.Title = "Site Manager";
}

<h2>Site Manager</h2>

<h5>@Html.ActionLink("Add New Site", "Create")</h5>

{

关于我在这里做错了什么有什么想法吗？

我最终使用了会话变量，尽管它不是最好的方法。

if (Status != null)
        {
            System.Web.HttpContext.Current.Session["Status"] = Status;
        }

        if (System.Web.HttpContext.Current.Session["Status"] != null)
        {
            Status = System.Web.HttpContext.Current.Session["Status"].ToString();
        }

        if (Type != null)
        {
            System.Web.HttpContext.Current.Session["Type"] = Type;
        }

        if (System.Web.HttpContext.Current.Session["Type"] != null)
        {
            Type = System.Web.HttpContext.Current.Session["Type"].ToString();
        }

        if (Name != null)
        {
            System.Web.HttpContext.Current.Session["Name"] = Name;
        }

        if (System.Web.HttpContext.Current.Session["Name"] != null)
        {
            Name = System.Web.HttpContext.Current.Session["Name"].ToString();
        }

        if (Site != null)
        {
            System.Web.HttpContext.Current.Session["Site"] = Site;
        }

        if (System.Web.HttpContext.Current.Session["Site"] != null)
        {
            Site = System.Web.HttpContext.Current.Session["Site"].ToString();
        }

        if (Acct != null)
        {
            System.Web.HttpContext.Current.Session["Acct"] = Acct;
        }

        if (System.Web.HttpContext.Current.Session["Acct"] != null)
        {
            Acct = System.Web.HttpContext.Current.Session["Acct"].ToString();
        }

        if (City != null)
        {
            System.Web.HttpContext.Current.Session["City"] = City;
        }

        if (System.Web.HttpContext.Current.Session["City"] != null)
        {
            City = System.Web.HttpContext.Current.Session["City"].ToString();
        }

        if (State != null)
        {
            System.Web.HttpContext.Current.Session["State"] = State;
        }

        if (System.Web.HttpContext.Current.Session["State"] != null)
        {
            State = System.Web.HttpContext.Current.Session["State"].ToString();
        }

        if (Address != null)
        {
            System.Web.HttpContext.Current.Session["Address"] = Address;
        }

        if (System.Web.HttpContext.Current.Session["Address"] != null)
        {
            Address = System.Web.HttpContext.Current.Session["Address"].ToString();
        }
