Hello,

Spent hours trying to get this simple update sample to work. Firefox shows that my model is being sent to my controller on an update but my controller receives a null model. I must be missing something basic. Thank you in advance. VS2012.

Firefox debug info:

Parametersapplication/x-www-form-urlencoded

models
[{"OnTimeID":123,"Description":"Altamed staging issue","Status":"closed"}]

View:

<!doctype html>

<html>

@{

ViewBag.Title = "OnTime Sample";

}

<head>

<title>Kendo UI Web</title>

<link href="~/styles/kendo.common.min.css" rel="stylesheet" />

<link href="~/styles/kendo.default.min.css" rel="stylesheet" />

<script src="~/js/jquery.min.js"></script>

<script src="~/js/kendo.web.min.js"></script>

<body>

<div class="form">

<div class="selector">

Edit Product:

<input type="text" id="onTimeIDs" />

</div>

<div id="container" class="container">

<ul>

<li>

<label>

OnTime ID</label>

<span data-bind="text:OnTimeID"></span></li>

var crudServiceBaseUrl = "/Services",

dataSource = new kendo.data.DataSource({

transport: {

read: {

url: crudServiceBaseUrl + "/OnTimeIDs_Get",

dataType: "json"

},

url: crudServiceBaseUrl + "/OnTimeIDs_Update",

type: "POST",

parameterMap: function (options, operation) {

if (operation !== "read" && options.models) {

return {

models: kendo.stringify(options.models)

};

}

},

batch: true,

schema: {

model: {

id: "OnTimeID",

fields: {

OnTimeID: {

editable: false,

nullable: true

},

Description: { type: "string" },

Status: { type: "string" }

}

);

$("#onTimeIDs").kendoDropDownList({

dataSource: dataSource,

dataTextField: "Description",

dataValueField: "OnTimeID",

change: function () {

var model = dataSource.get(this.value());

kendo.bind($("#container"), model);

}

}).data("kendoDropDownList")

.one("dataBound", function () {

kendo.bind($("#container"), dataSource.view()[0]);

});

$("button").click(function () {

dataSource.sync();

});

</script>

</body>

Controller:

Why does OnTimeIDs_Update() receive a null parameter?

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.Mvc;

using MVCTimeCard.Models;

namespace MVCTimeCard.Controllers

{

public class ServicesController : Controller

{

public ActionResult OnTimeIDs_Get()

{

List<OnTimeItem> otiList = new List<OnTimeItem>() {

new OnTimeItem {OnTimeID = 123, Description = "Altamed staging issue", Status = "Open"},

new OnTimeItem {OnTimeID = 456, Description = "HILL staging issue", Status = "Open"},

new OnTimeItem {OnTimeID = 789, Description = "PPMSI staging issue", Status = "Open"}

};

return Json(otiList, JsonRequestBehavior.AllowGet);

}

[HttpPost]

public ActionResult OnTimeIDs_Update( IEnumerable< OnTimeItem> otis)

{

return Json(otis, JsonRequestBehavior.AllowGet);

}
