我正在使用免费的Kendo web控件。我之前在几个地方使用了网格视图，并决定使用弹出式样式编辑来处理当前项目。Kendo.Web Grid Popup使用组合框创建
我大部分工作。我有三个组合框用于分类，银行账户和收款人，当我编辑现有项目时，传回我的MVC操作的模型对象具有正确的值。但是，当我单击创建按钮时，三个组合框值将作为null返回给控制器。
下面是对这一观点的CSHTML代码：
@using System
@using System.Linq
@{
ViewBag.Title = "Transactions";
}
@section Head
{
<link href="~/Content/kendo/kendo.common.min.css" rel="stylesheet" />
<link href="~/Content/kendo/kendo.default.min.css" rel="stylesheet" />
<script src="~/Scripts/kendo/kendo.web.min.js"> </script>
}
@section featured
{
<section class="featured">
<div class="content-wrapper">
<hgroup class="title">
<h1>@ViewBag.Title</h1>
</hgroup>
</div>
</section>
}
<div id="grid"></div>
<script>
$(function() {
$("#grid").kendoGrid({

结合到剑道组合框必须正常工作，否则编辑也会失败。我能想到的是该对象没有正确创建。此外，它默认选择组合框中的第一项，但即便如此，也不会绑定该值。
以下是我的创造和更新操作的代码：
[HttpPost]
public ActionResult Create(TransactionModel transactionModel)
{
var transaction = _moneyBO.CreateTransaction();
Mapper.Map(transactionModel, transaction);
_moneyBO.UpdateTransaction(transaction);
return Json(Mapper.Map<TransactionModel>(transaction));
}
public ActionResult Update(TransactionModel transactionModel)
{
var transaction = _moneyBO.Transactions.SingleOrDefault(x => x.Id == transactionModel.Id);
if (transaction == null)
return View("NotFound");
Mapper.Map(transactionModel, transaction);
_moneyBO.UpdateTransaction(transaction);
return Json(Mapper.Map<TransactionModel>(transaction));
}
我还没有发现使用弹出自定义编辑一个很好的例子。 Kendo网站上的示例以内联方式工作，但如果将示例更改为弹出式窗口，则不起作用。
我没有注意到。谢谢，我今晚会尝试一下，看看有没有什么不同。我的猜测可能不是，因为编辑工作在相同的连接，但谁知道。 – 2013-03-13 18:27:16
上周我一直忙于其他项目。希望在这个周末看看这个。 – 2013-03-23 02:00:43
