我正在使用免費的Kendo web控件。我之前在幾個地方使用了網格視圖，並決定使用彈出式樣式編輯來處理當前項目。Kendo.Web Grid Popup使用組合框創建
我大部分工作。我有三個組合框用於分類，銀行賬戶和收款人，當我編輯現有項目時，傳回我的MVC操作的模型對象具有正確的值。但是，當我單擊創建按鈕時，三個組合框值將作爲null返回給控制器。
下面是對這一觀點的CSHTML代碼：
@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({
height: 350,
toolbar: [{ name: "create", text: "Create New Transaction" }],
columns:
[
{ field: "Date", width: "100px", template: '#= kendo.toString(Date,"MM/dd/yyyy") #' },

{ field: "Category", width: "80px", editor: categoryDropDownEditor, template: "#=Category.Name#" },
{ field: "BankAccount", title: "Account", width: "80px", editor: bankAccountDropDownEditor, template: "#=BankAccount.Name#" },

}
});
function categoryDropDownEditor(container, options)
{
$('<input required data-text-field="Name" data-value-field="Id" data-bind="value:' + options.field + '"/>')
.appendTo(container)
.kendoDropDownList(

結合到劍道組合框必須正常工作，否則編輯也會失敗。我能想到的是該對象沒有正確創建。此外，它默認選擇組合框中的第一項，但即便如此，也不會綁定該值。
以下是我的創造和更新操作的代碼：
[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));
}
我還沒有發現使用彈出自定義編輯一個很好的例子。 Kendo網站上的示例以內聯方式工作，但如果將示例更改爲彈出式窗口，則不起作用。
我沒有注意到。謝謝，我今晚會嘗試一下，看看有沒有什麼不同。我的猜測可能不是，因爲編輯工作在相同的連接，但誰知道。 – 2013-03-13 18:27:16
上週我一直忙於其他項目。希望在這個週末看看這個。 – 2013-03-23 02:00:43
