无法在GridMVC.html中实现分页成功？

Question

我正在使用GridMvc来填充文档详细信息。下面是视图中的GridMvc代码：

 <div style="width:5000px;">

        @Html.Grid(Model.allDocs).Columns(columns => 
                    {
                        columns.Add(c => c.SourceFileName).Titled("SourceFileName").Filterable(true).Sanitized(false).Encoded(false)
                            .RenderValueAs(o => Html.ActionLink(o.SourceFileName, "Download", "FormAdmin", new { Id = o.DataFileID }, new { target = "_blank" }).ToHtmlString());
                        columns.Add(c => c.ID).Titled("ID");
                        //columns.Add(c => c.SourceFileName).Titled("SourceFileName").Filterable(true);
                        columns.Add(c => c.Createdate).Titled("CreateDate");
                        columns.Add(c => c.customerName).Titled("customerName");
                        columns.Add(c => c.CompanyName).Titled("CompanyName");


                    }).WithPaging(3).Sortable(true)
    </div>

以下是我在控制器中的代码：

public ActionResult DocDetails()
        {
            DocViewModel obj = new DocViewModel();


            obj.allDocs = new DocumentDetailsModel().GetDocumentViewModel();

            obj.ClientCodeLst = new DocumentDetailsModel().GetClientViewModel().ClientCodeLst;

            // obj.allSearch = new SearchParameters();
            obj.searchParam = new SearchParameters();

            return View(obj);
        }

     [HttpPost]
        public ActionResult DocDetails(DocViewModel b)
        {
            DocViewModel obj2 = new DocViewModel();




            //if (ModelState.IsValid)
            //{

                obj2.allDocs = new DocumentDetailsModel().GetDocumentbySearch(b.searchParam.ID);

                obj2.ClientCodeLst = new DocumentDetailsModel().GetClientViewModel().ClientCodeLst;

                obj2.searchParam = new SearchParameters();

            //}
            return View(obj2);
        }

用户选择特定值并使用特定于这些值的记录填充网格。 获取值并使用这些数据填充网格后，当用户单击分页以获取下一个记录数据集时，网格将填充所有默认数据，但不会导航到具有特定值的下一组数据。

有人能让我知道我在哪里理解概念吗？

更新：

 public List<GetDocumentsParam> GetDocumentViewModel()
        {
            var fnResult1 = new List<GetDocumentsParam>();

            var edmx = new RepositoryEntities1();
            var getDocs = new GetDocumentsParam();



            return fnResult1 ;
        }

        public GetClientCodes GetClientViewModel()
        {
            var fnResult = new GetClientCodes();
            var edmx = new RepositoryEntities1();
            fnResult.ClientCodeLst = edmx.Clients
                                  .Select(s => s.ClientCode)
                                  .Distinct()
                                  .Select(s => new SelectListItem { Text = s, Value = s }).ToList();

            return fnResult;

        }

        public List<GetDocumentsParam> GetDocumentbySearch(DateTime date)
        {

            fnResult = new List<GetDocumentsParam>();
            //GetDocumentsParam objDoc = new GetDocumentsParam();
            var objDoc1 = (from c in db.DFiles
                               join b in db.BDatas
                               on c.ID equals b.ID
                               join d in db.Documents
                               on c.ID equals d.ID
                               where d.CreateDate == date
                               select new GetDocumentsParam
                               {
                                   ID = c.ID,
                                   SourceFileName = c.SourceFileName,
                                   Createdate = c.CreateDate,
CompanyName = c.CompanyName,
CustomerName = c.CustomerName,
                                                                      ClientCode = c.ClientCode


                               });
            fnResult = objDoc1.ToList();
           // fnResult = queryResults;
            return fnResult;
        }

public class DocViewModel
    {

        public List<GetDocumentsParam> allDocs { get; set; }
        public List<SelectListItem> ClientCodeLst { get; set; }

        public SearchParameters searchParam { get; set; }
    }
