【问题描述】：
我有一个索引页面，上面有各种过滤选项，都包含在 PagedList 中。除了日期之外，它们似乎都工作正常。
当我第一次按日期过滤时，它们工作正常，但是当我点击底部的页码时，我的日期的搜索条件消失了。
我可以看到我可以在分页列表中传递搜索词，我可以看到这个日期命中了我的控制器并且过滤发生了，但是 ViewBag.filterStartDate 和 ViewBag.filterEndDate 只是没有绑定回我的文本框某种原因。
Index.cshtml：
@using PagedList.Mvc
@model PagedList.IPagedList<Job>
@using (Html.BeginForm("Index", "Jobs", FormMethod.Get, new { @class = "form-inline", role = "form" }))
{
<div class="panel panel-default">
<!-- Default panel contents -->
<div class="panel-heading">Filter Search Results</div>
<div class="panel-body">
<ul class="list-group">
<li class="list-group-item">
@Html.Label("By Id: ", new { @class = "col-md-4 control-label" })
@Html.TextBox("filterId", ViewBag.filterId as string, new { @class = "form-control" })
</li>
<li class="list-group-item">
@Html.Label("By Address Line 1: ", new { @class = "col-md-4 control-label" })
@Html.TextBox("filterAddress1", ViewBag.filterAddress1 as string, new { @class = "form-control" })
</li>
<li class="list-group-item">
@Html.Label("By Username: ", new { @class = "col-md-4 control-label" })
@Html.TextBox("filterUsername", ViewBag.filterUsername as string, new { @class = "form-control" })
</li>
<li class="list-group-item">
@Html.Label("By Contract: ", new { @class = "col-md-4 control-label" })
@Html.DropDownList("filterContract", null, "-- Select One --",

@Html.Label("Date Created Start: ", new { @class = "col-md-4 control-label" })
@Html.TextBox("filterStartDate", ViewBag.filterStartDate as string, new { @class = "form-control date", type = "date" })

<li class="list-group-item">

@Html.TextBox("filterFinishDate", ViewBag.filterFinishDate as string, new { @class = "form-control date", type = "date" })
</li>
<li class="list-group-item">
@Html.Label("By App: ", new { @class = "col-md-4 control-label" })

JobsController.cs：

jobs = jobs.Where(x => x.DateCreated >= filterStartDate);
//ViewBag.filterStartDate = filterStartDate.Value.Year + "-" + filterStartDate.Value.Month + "-" + filterStartDate.Value.Day;
ViewBag.filterStartDate = filterStartDate;
}
if (filterFinishDate != null)
{
//Make sure we're checking to the end of the end date (ie 01/01/2015 23:59:59)
filterFinishDate = filterFinishDate.Value.AddHours(23).AddMinutes(59).AddSeconds(59);
jobs = jobs.Where(x => x.DateCreated <= filterFinishDate);
//ViewBag.filterFinishDate = filterFinishDate.Value.Year + "-" + filterFinishDate.Value.Month + "-" + filterFinishDate.Value.Day;
ViewBag.filterFinishDate = filterFinishDate;
}
int pageSize = int.Parse(ConfigurationManager.AppSettings["MaxPageItemCount"]);
int pageNumber = page ?? 1;
return this.View(jobs.ToPagedList(pageNumber, pageSize));
}
【问题讨论】：
-
从索引操作返回作业时，它们的排序是否正确？
-
目前我实际上并没有使用任何排序。当前未使用 sortOrder。相反，我只是按 DateCreated DESC 对它们进行排序，但我选择省略那行代码，因为我认为这对我遇到的问题并不重要。
