网格视图分页-ASP.net mvc和linq

我正在使用nop commercer2.6 所以我想打包自定义报告，我想为该报告进行分页。网格视图分页-ASP.net mvc和linq

这是我的功能

public virtual IPagedList<HireItemReportLine> HireItemReport(int ceremony_id, string Fname, string Mname, string Lnmae, string emailAdd, int sesson_id, int pageIndex, int pageSize) 
     { 

      var query1 = from opv in _opvRepository.Table 
         join o in _orderRepository.Table on opv.OrderId equals o.Id 
         join gr in _graduandRepository.Table on opv.graduand_id equals gr.Id 
         join pv in _productVariantRepository.Table on opv.ProductVariantId equals pv.Id 
         join p in _productRepository.Table on pv.ProductId equals p.Id 
         join c in _ceremonyRepository.Table on gr.ceremony_id equals c.Id 
         join s in _seasonRepository.Table on c.season_id equals s.Id 
         where (!o.Deleted) && (opv.IsHireItem == true) && 
         (!p.Deleted) && 
         (!pv.Deleted) 
         select new 
         { 
          opvTable = opv, 
          grTable = gr, 
          seaTable = s, 

         }; 

      if (!(sesson_id == 0)) 
       query1 = query1.Where(item => item.seaTable.Id == sesson_id); 

      if (!(ceremony_id == 0))     
       query1 = query1.Where(item => item.opvTable.ceremony_id == ceremony_id); 

      if (!String.IsNullOrEmpty(Fname)) 
       query1 = query1.Where(item => item.grTable.first_name == Fname); 

      if (!String.IsNullOrEmpty(Mname)) 
       query1 = query1.Where(item => item.grTable.middle_name == Mname); 

      if (!String.IsNullOrEmpty(Lnmae)) 
       query1 = query1.Where(item => item.grTable.last_name == Lnmae); 

      if (!String.IsNullOrEmpty(emailAdd)) 
       query1 = query1.Where(item => item.grTable.email == emailAdd); 


      var query2 = from opv in query1 
          group opv by opv.opvTable.OrderId into g 
          select new 
          { 
           OrderId = g.Key, 
           TotalAmount = g.Sum(x => x.opvTable.PriceInclTax), 


          }; 
int totalCount = query2.Count(); 
      query2 = query2.OrderByDescending(x => x.OrderId); 

      var result = query2.ToList().Select(x => 
      { 
       return new HireItemReportLine() 
       { 
        OrderId = x.OrderId,     
        Amount= x.TotalAmount, 

       }; 
      }); 

      var orders_1 = result.ToList();  


      return new PagedList<HireItemReportLine>(orders_1, pageIndex, pageSize,totalCount); 
     }

这是PagedLis（）函数

public PagedList(IEnumerable<T> source, int pageIndex, int pageSize, int totalCount) 
    { 
     TotalCount = totalCount; 
     TotalPages = TotalCount/pageSize; 

     if (TotalCount % pageSize > 0) 
      TotalPages++; 

     this.PageSize = pageSize; 
     this.PageIndex = pageIndex; 
     this.AddRange(source); 

    }

我想这个数据网格视图结合并具有分页。我可以绑定，它显示的页码。但我的问题是，当我点击页面号的网格视图时，它总是只显示第一页。你有什么想法吗？

我认为使用第三方工具时，这些分页/排序/分组会变得更容易。但是，请查看下面的链接，在LINQ中使用c＃进行分页/排序。
