Kendo UI网格数据绑定

Question

我很遗憾将网格重新绑定到从AJAX调用收到的数据。日期会丢失格式。

@{
    ViewBag.Title = "Index";
}

@section Scripts {
    <script type="text/javascript">
        var viewModel;

        $(function () {
            // Load Data
            $.ajax({
                async: false,
                url: "/Kendo/Home/GetData"
            }).success(function (result) {
                viewModel = new kendo.observable(result);
            });

            // Create Grid
            $("#grid").kendoGrid({
                dataSource: {
                    data: viewModel.People,
                    schema: {
                        model: {
                            fields: {
                                DOB: { type: "date" }
                            }
                        }
                    }
                },
                columns: [
                    { field: "FirstName", title: "First Name" },
                    { field: "LastName", title: "Last Name" },
                    { field: "DOB", title: "Date of Birth", format: "{0:MM/dd/yyyy}" }
                ],
                editable: true
            });

            $(document).on("click", "#btn-save", function (e) {
                $.ajax({
                    url: "/Kendo/Home/Save",
                    type: "POST",
                    data: JSON.stringify(viewModel),
                    contentType: "application/json"
                }).success(function (result) {
                    var g = $("#grid").data("kendoGrid");
                    viewModel = new kendo.observable(result);
                    g.dataSource.data(viewModel.People);

                });
            });
        });
    </script>
}

<div id="grid"></div>
<div id="view">
    <input data-bind="value: firstName" />
    <input data-bind="value: lastName" />
    <button id="btn-save">Save</button>
</div>

加载的初始数据是：

{"People":[{"FirstName":"Sam","LastName":"Striano","DOB":"\/Date(215420400000)\/"},{"FirstName":"Karson","LastName":"Striano","DOB":"\/Date(321609600000)\/"}]}

从AJAX调用返回的数据（通过“保存”按钮）是：

{"People":[{"FirstName":"Sam 1234","LastName":"Striano","DOB":"\/Date(216288000000)\/"},{"FirstName":"Karson 1234","LastName":"Striano","DOB":"\/Date(322473600000)\/"}]}
