Question

当我选择一个类别时，我收到的这个问题没有显示。没有项目没有分页。

跟随PagedList的Troy Goodes示例但无法使其正常工作。 jQuery加载三个部分视图（类别，项目.descrip），我正在尝试对项目结果进行分页

这是我的控制器

public ActionResult Partial( int id, int? page) 
    {

        var Uid = WebSecurity.GetUserId(User.Identity.Name);
        var pageNumber = page ?? 1;

        var query = from i in db.Items
                    where i.user_id == Uid && i.catId == id
                    select i;
        var results = query;
        var onePageOfProducts = results.ToPagedList(pageNumber, 10);

         return PartialView("_Partial1", onePageOfProducts);

    }

查看

@using IPagedList;
@using PagedList.Mvc;

@*@foreach (var item in Model)
{*@


@foreach(var item in ViewBag.OnePageOfProducts){



    <tr data-id="@item.ID">
        <td data-id="@item.ID">@item.item_name</td>
        <td></td>
    </tr>

 }
 @Html.PagedListPager( (IPagedList)ViewBag.OnePageOfProducts, 
  page => Url.Action("/Item/Partial", new { page }) )

的jQuery

    $('#categories').load("/Category/GetCats", function () {

            $(this).on("click","tr", function () {
                var requestpage = "/Item/Partial?id=" + $(this).data("id");
                //alert(requestpage);   //debug

                $.get(requestpage, function (result) {
                    $("#results").html(result);

                });
            });
        });

        $('#results').load("/Item/Partial", function () {
            var buttons =  
    $("<button class=\"removeBtn\">Remove</button>
    <button class=\"removeBtn\">Edit</button>");

            $(this).on("click", "tr", function () {
                var requestpage = "/Item/FullInfoPartial?id=" + $(this).data("id");
                buttons.appendTo(this);
                //alert(requestpage);  //debug
                $.get(requestpage, function (result) {
                    $("#descrip").html(result);
                });
            });
        });

为了给你一个详细的答案，我应该看到你收到的问题，因为你没有提到到底出了什么问题。无论如何，我已经在你的代码中看到了一些问题。

您正在调用ViewBag.OnePageOfProducts，但您没有在ActionResult中创建此ViewBag。所以修改如下：

public ActionResult Partial( int id, int? page) 
{

    var Uid = WebSecurity.GetUserId(User.Identity.Name);
    var pageNumber = page ?? 1;

    var query = from i in db.Items
                where i.user_id == Uid && i.catId == id
                select i;
    var results = query;
    var onePageOfProducts = results.ToPagedList(pageNumber, 10);

     ViewBag.OnePageOfProducts = onePageOfProducts; //* You've fogotten to add this line

     return PartialView("_Partial1", onePageOfProducts);

}

您正在使用id参数，但您在@Html.PagedListPager助手中已经忘记了它。如果您没有定义它，PagedList将从第二页开始丢失结果。所以修改它：
```
@Html.PagedListPager( (IPagedList)ViewBag.OnePageOfProducts, 
page => Url.Action("/Item/Partial", new { page = page, id = item.ID})
```

PagedList分页不起作用Mvc4
