我正在尝试使用带有C＃的ASP MVC 5创建一个页面，其中我有一些控件来输入搜索参数和一个显示结果的表。
问题是应该允许用户编辑表格中两个字段的文本并保存更改。
为了实现这一点，我的视图接收一个模型，其中有两个对象作为属性，一个用于搜索参数，一个用于结果列表，如下所示：
public class SEARCH_PAGE
{
public List<VIEW_DATA_APR> table{ get; set; }
public SEARCH parameters{ get; set; }
}
然后我的控制器是这样的：
public class CargaAPRController : Controller
{
private datasource db = new datasource();
// GET: CargaAPR
public ActionResult Index()
{
try
{
List<SelectListItem> items = new SelectList(db.COMPANY, "IDCOMPANY", "COMPANYNAME").ToList();
items.Insert(0, (new SelectListItem { Text = "ALL", Value = "0" }));
ViewData["IDCOMPANY"] = items;
var letters = (from c in db.LETTERS
select new VIEW_DATA_APR
{
company = c.COMPANY.COMPANYNAME,
idLetter = c.IDLETTER,
nic = "not found",
client = "not found",
energy = 0,
money = 0,
period = "",
letterCode = c.LETTERCODE
});
SEARCH_PAGE sp = new SEARCH_PAGE();
sp.table= letters.ToList();
sp.parameters= new SEARCH();
return View(sp);
}
catch (Exception ex)
{
return RedirectToAction("Error", new RouteValueDictionary(new { controller = "Users", action = "Error", mensaje = "Error: " + ex.Message }));
}
}
[HttpPost]
public ActionResult Index(SEARCH_PAGE model)
{
try
{
List<SelectListItem> items = new SelectList(db.COMPANY, "IDCOMPANY", "COMPANYNAME").ToList();
items.Insert(0, (new SelectListItem { Text = "ALL", Value = "0" }));
ViewData["IDCOMPANY"] = items;
decimal company = Decimal.Parse(model.parameters.company);
var letters= (from c in db.LETTERS
where (company== 0 ? c.IDCOMPANY: company) == c.IDCOMPANY
select new VIEW_DATA_APR
{
company= c.COMPANY.COMPANYNAME,
idLetter= c.IDLETTER,
nic = "not found",
client = "not found",
energy = 0,
money = 0,
period = "",
letterCode = c.LETTERCODE
});
SEARCH_PAGE sp = new SEARCH_PAGE();
sp.table= letters.ToList();
sp.parameters = model.parameters;
return View(sp);
}
catch (Exception ex)
{
return RedirectToAction("Error", new RouteValueDictionary(new { controller = "Users", action = "Error", mensaje = "Error: " + ex.Message }));
}
}
[HttpPost]
public ActionResult Save(SEARCH_PAGE model_search_page )
{
return View();
}
}
我的观点是：
@using datasource.Models
@model SEARCH_PAGE
@{
ViewBag.Title = "Load APR";
Layout = "~/Views/Shared/_Layout.cshtml";
}
@Styles.Render("~/Content/energetica.css")
<meta name="viewport" content="width=device-width" />
<title>Letters</title>
<link href="@Url.Content("~/Content/Site.css")" rel="stylesheet" type="text/css" />
<div class="container-fluid">
<div class="col-md-1">
</div>
<div class="col-md-10">
<div class="panel panel-default">
<!-- Default panel contents -->
<div class="panel-heading">
<div class="row">
<div class="col-md-1">
<a href="@Url.Action("Index", "LoadFiles")" class="elements">
<img class="img img-responsive" style="width:25px; height:26px;padding:1px" src="~/img/BackIcon.png">
</a>
</div>
<div class="col-md-11 text-left" style="padding:1px;">
LOAD APR
</div>
</div>
</div>
</div>
@using (Html.BeginForm("Index","LoadAPR", FormMethod.Post, null))
{
<table style="width:100%">
<tr>
<td style="width:10%">
<b>COMPANY: </b>
</td>
<td style="width:20%">
@Html.DropDownListFor(m => m.parameters.company, (IEnumerable<SelectListItem>)ViewData["IDCOMPANY"], new { htmlAttributes = new { @class = "form-control" } })
</td>
<td style="width:10%">
<b>PERIOD: </b>
</td>
<td style="width:20%">
@Html.EditorFor(m => m.parameters.period)
</td>
<td style="width:20%; text-align:right">
<input type="submit" name="SEARCH" value="SEARCH" />
</td>
</tr>
<tr>
<td style="width:10%">
<b>CLIENT: </b>
</td>
<td style="width:20%">
@Html.EditorFor(m => m.parameters.client)
</td>
<td style="width:10%">
<b>NIC: </b>
</td>
<td style="width:20%">
@Html.EditorFor(m => m.parameters.nic)
</td>
</tr>
</table>
}
<br />
@using (Html.BeginForm("Save", "LoadAPR", FormMethod.Post, null))
{
<div style="overflow-y: scroll; max-height: 300px">
<table style="width:100%">
<tr>
<th>
@Html.Label("LBDIS", "Company")
</th>
<th>
@Html.Label("LBNLETTER", "Letter Code")
</th>
<th>
@Html.Label("LBNIC", "NIC")
</th>
<th>
@Html.Label("LBCLIENT", "Client")
</th>
<th>
@Html.Label("LBENERGY", "Energy")
</th>
<th>
@Html.Label("LBMONEY", "Money")
</th>
</tr>
@foreach (var item in Model.table)
{
<tr>
<td>
@Html.DisplayFor(modelItem => item.company)
</td>
<td>
@Html.DisplayFor(modelItem => item.letterCode)
</td>
<td>
@Html.DisplayFor(modelItem => item.nic)
</td>
<td>
@Html.DisplayFor(modelItem => item.client)
</td>
<td>
@Html.EditorFor(modelItem => item.energy)
</td>
<td>
@Html.EditorFor(modelItem => item.money)
</td>
</tr>
}
</table>
</div>
<br />
<div style="width:100%; text-align:right;">
<input class="btn-addUser" type="submit" value="Save" />
</div>
}
</div>
所以当我运行它并单击我的第一个按钮时，POST Index参数只接收对象的参数部分，表部分为空
当我点击第二个按钮时，POST Save参数在两个属性中都为空。
我尝试了很多不同的方式将模型作为参数进行查找，但没有任何工作。你能告诉我什么是错的吗？我是否以正确的方式使用BeginForm？
提前谢谢。
