分页列表的示例-ASP.NETMVC

本文关键字:-ASP NETMVC 列表 分页 | 更新日期: 2023-09-27 18:29:48

对包含列表的模型进行分页的最佳方式是什么?

根据下面的模型,我希望浏览我的公司模型上的"电子邮件"。我目前正在尝试使用PagedListMVC来实现这一点。

型号示例

public class EmailModel
{
    public Guid Id { get; set; }
    public string EmailMessage { get; set; }
    public Guid CompanyId { get; set; }
}
public class CompanyModel
{
    public Guid Id { get; set; }
    public string CompanyName { get; set; }
    public IPagedList<Email> Emails { get; set; }
}

我的页面有一个显示电子邮件的部分视图

@Html.Partial("_CompanyEmails.cshtml", Model.Emails);

有人能给我举一个控制器的例子来处理这个问题吗?

您查看过文档吗?

页面下方大约三分之二的标题是:

为索引方法添加分页功能


控制器


给出的样本(在其上下文中)是:

using PagedList;
...
...
public ViewResult Index(string sortOrder, string currentFilter, string searchString, int? page)
{
   ViewBag.CurrentSort = sortOrder;
   ViewBag.NameSortParm = String.IsNullOrEmpty(sortOrder) ? "name_desc" : "";
   ViewBag.DateSortParm = sortOrder == "Date" ? "date_desc" : "Date";
   if (searchString != null)
   {
      page = 1;
   }
   else
   {
      searchString = currentFilter;
   }
   ViewBag.CurrentFilter = searchString;
   var students = from s in db.Students
                  select s;
   if (!String.IsNullOrEmpty(searchString))
   {
      students = students.Where(s => s.LastName.ToUpper().Contains(searchString.ToUpper())
                             || s.FirstMidName.ToUpper().Contains(searchString.ToUpper()));
   }
   switch (sortOrder)
   {
      case "name_desc":
         students = students.OrderByDescending(s => s.LastName);
         break;
      case "Date":
         students = students.OrderBy(s => s.EnrollmentDate);
         break;
      case "date_desc":
         students = students.OrderByDescending(s => s.EnrollmentDate);
         break;
      default:  // Name ascending 
         students = students.OrderBy(s => s.LastName);
         break;
   }
   int pageSize = 3;
   int pageNumber = (page ?? 1);
   return View(students.ToPagedList(pageNumber, pageSize));
}

查看


如果没有要显示的页面;第0页,共0页";显示。(在这种情况下,页码大于页数,因为Model.PageNumber为1,Model.PageCount为0。)

页面按钮由PagedListPager助手显示:

@Html.PagedListPager( Model, page => Url.Action("Index", new { page }) )
