问题描述
型号:
Model:
public class Cedim
{
public float PEGID { get; set; }
public float PIGID { get; set; }
public float Type { get; set; }
}
查看:
View:
@model PagedList.IPagedList<AvibuyerExcelUpload.Models.Cegedim>
@using PagedList.Mvc;
<link href="~/Content/PagedList.css" rel="stylesheet" />
<h2>Upload File</h2>
@using (Html.BeginForm("Index", "Upload", null, FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.AntiForgeryToken()
@Html.ValidationSummary()
<div class="form-group">
<input type="file" id="dataFile" name="upload" />
</div>
<div class="form-group">
<input type="submit" name="Command" value="Upload Cegedim" class="btn btn-default" />
</div>
if (Model != null)
{
<table>
<thead>
<tr>
<th>PIGID</th>
<th>Type</th>
</tr>
</thead>
<tbody>
@foreach (var item in Model)
{
<tr>
<td>@Html.DisplayFor(x => item.PIGID)</td>
<td>@Html.DisplayFor(x => item.Type)</td>
</tr>
}
</tbody>
</table>
}
if (Model.PageCount > 1)
{
<div class="pager">
@Html.PagedListPager(Model, page => Url.Action("Index", new { page,currentFilter=ViewBag.CurrentFilter, sortOrder = ViewBag.CurrentFilter}))
Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount
</div>
}
}
控制器:
Controller:
public ActionResult Index(int page=1)
{
if (Session["Final"] == null)
{
List<Cegedim> listCegedim = new List<Cegedim>();
listCegedim = new List<Models.Cegedim>();
return View(listCegedim.ToPagedList(1,50));
}
else
{
DataTable dtCegedim = (DataTable)Session["Final"];
int SkipRows = (page-1) * 50;
DataTable newDtCegedim = new DataTable();
newDtCegedim = dtCegedim.AsEnumerable().Skip(SkipRows).Take(50).CopyToDataTable();
List<Cegedim> myList = new List<Cegedim>();
myList = (from rw in newDtCegedim.AsEnumerable()
select new Cegedim()
{
PIGID = Convert.ToInt32(rw["PIGID"]),
Type = Convert.ToInt32(rw["Type"])
}).ToList();
return View(myList.ToPagedList(page,50));
}
}
我的尝试:
当我点击第二页时,模型在Controller中填充并传递给View但在View上变为空。
What I have tried:
When i click 2nd Page , the model is filled in Controller and passed to View but it becomes empty on View.
