ASP.NET MVC分页，保留当前查询参数 [英] ASP.NET MVC Paging, Preserving Current Query Parameters

问题描述

我有一个包含联系信息的网格，我需要能够对其进行分页.

I have a grid with contact information which I need to be able to page through.

所有管道均已安装到位，最后一个细节.分页是通过简单的p Querystring参数完成的，例如www.myurl.com/grid?p=3将是第三页；资源库将自动获取正确的数据以及项目总数.每个页面的大小在其他地方定义，我不必担心查询字符串中的大小.

All the plumbing is already in place, with one last detail. Paging is done through a simple p Querystring parameter, e.g. www.myurl.com/grid?p=3 would be the third page; the repository is automatically fetching the right data, and also the total count of items. The size of each page is defined somewhere else and I don't need to worry about that in the query string.

但是，我也支持搜索等.在我的查询字符串中以q表示的搜索词.因此，现在我可以使用一个组合:www.myurl.com/grid?q=tom&p=2，它搜索"tom"并拉出第二页结果.

However, I support searching etc. as well. The search term searched for in denoted as q in my Querystring. So now I can have a combination: www.myurl.com/grid?q=tom&p=2 which searches for "tom" and pulls the second page of results.

我现在面临的问题，因为查询字符串中可能存在q(或其他)参数 ，我如何为此创建寻呼机(需要保持原始参数，因此，如果我单击第2页"，则需要从

The problem I face now, since the q (or other) parameters may be present in the query string, how do I create a pager for this (which would need to keep the original parameters, so if I click on "page 2" it needs to go from

• www.myurl.com/grid?a=1&b=xyz&q=tom

• www.myurl.com/grid?a=1&b=xyz&q=tom

到

www.myurl.com/grid?a=1&b=xyz&q=tom&p=2

www.myurl.com/grid?a=1&b=xyz&q=tom&p=2

我该怎么做?

以下是从史蒂夫·桑德森(Steve Sanderson)的书

following is the code copied from Steve Sanderson's book

public static class PagingHelpers
{
    public static string PageLinks(this HtmlHelper html, int currentPage,
    int totalPages, Func<int, string> pageUrl)
    {
        StringBuilder result = new StringBuilder();
        for (int i = 1; i <= totalPages; i++)
        {
            TagBuilder tag = new TagBuilder("a"); // Construct an <a> tag

            tag.MergeAttribute("href", pageUrl(i));
            tag.InnerHtml = i.ToString();
            if (i == currentPage)
                tag.AddCssClass("selected");


            result.AppendLine(tag.ToString());
        }
        return result.ToString();
    }
}
