Asp.net MVC格式后和分页

问题描述

我有一个动作方法搜索，当窗体发布被调用。可能有数以千计的搜索resulst基于形式公布值。我想说明逐页搜索查看的页面，但我怎么能知道什么形式值被张贴第一次？这样我可以通过传递页面参数调用搜索查看。

I have an action method Search, which is called when a form is posted. There could be thousands of search resulst based on posted values of form. I want to show Search View page by page, but how can I know what form values was posted first time? so that I can call Search View by passing page parameters.

推荐答案

在我的应用程序，为电网提供数据的所有操作方法都作为参数，这个类的一个实例：

In my app all the action methods that provide data to grids take as a parameter an instance of this class:

    public class QuerySettings
    {
        private int page;

        public QuerySettings()
            : this(true)
        { 
        }

        public QuerySettings(bool pagingEnabled)
        {
            this.Page = 1;
            this.Rows = 10;
            this.PagingEnabled = pagingEnabled;
        }

        public int Rows { get; set; }
        public string SortColumn { get; set; }
        public string SortOrder { get; set; }
        public string Search { get; set; }
        public bool PagingEnabled { get; set; }

        public int Page
        {
            get { return page; }
            set { page = Math.Max(1, value); }
        }
    }

此目的是通过它可以使用通过采取适当的排序/过滤信息业务层传递给服务方法英寸然后，他们返回包裹在数据：

This object is passed to service methods in by Business Layer which can use the information passed to apply appropriate sorting / filtering. They then return the data wrapped in:

public class QueryResult<T>
{
        public QueryResult()
        { 
        }

        public QueryResult(QuerySettings settings, IList<T> items, int currentPage, int totalPages, int totalItems)
        {
            Settings = settings;
            Items = items;
            CurrentPage = currentPage;
            TotalPages = totalPages;
            TotalItems = totalItems;
        }

        public QuerySettings Settings { get; private set; }
        public int CurrentPage { get; private set; }
        public int TotalPages { get; private set; }
        public int TotalItems { get; private set; }
        public IList<T> Items { get; private set; }

        public IEnumerable<T> AsEnumerable()
        {
            return this.Items;
        }
    }
