我已经从 ASP.NET MVC 的 Telerik Extensions ( Telerik Sample ) 中的编辑批处理示例中实现了 MVC3/Razor 网格控件，并且在大多数情况下，我认为它正在工作，但是我注意到虽然更新似乎是在客户端上工作，基础数据库表不会更新。
我认为我可能错过了执行此操作的某些步骤，但是在我使用 Northwind 数据库下载的 Telerik 示例中的产品名称的批量编辑示例中进行更新后，基础数据表也没有更改。
看法：
@model IEnumerable<MarketingWebsiteTools.Models.EditableCallout>
@using MarketingWebsiteTools.Extensions;
@using MarketingWebsiteTools.Models;
@{
ViewBag.Title = "Index";
Layout = "~/Views/Shared/_Layout.cshtml";
}
<h2>Marketing Messages</h2>
@(Html.Telerik().Grid<MarketingWebsiteTools.Models.EditableCallout>()
.Name("Grid")
.DataKeys(keys =>
{
keys.Add(p => p.id);
})
.ToolBar(commands =>
{
commands.Insert();
commands.SubmitChanges();
})
.Columns(columns =>
{
columns.Bound(o => o.ProductIdentifier).Width(125);
columns.Bound(o => o.DateStart).Width(75);
columns.Bound(o => o.DateEnd).Width(75);
columns.Bound(o => o.Value).Width(75);
columns.Bound(o => o.IsActive).Width(75);
columns.Command(commands => commands.Delete()).Width(125).Title("Delete");
})
.ClientEvents(events => events.OnDataBinding("Grid_onDataBinding").OnError("Grid_onError"))
.Editable(editing => editing.Mode(GridEditMode.InCell).DefaultDataItem(new EditableCallout
{
DateStart = DateTime.Today
}))
.DataBinding(dataBinding => dataBinding.Ajax()
.Select("_Index", "Callouts")
.Update("_SaveBatchEditing", "Callouts")
)
.Pageable()
.Scrollable()
.Sortable()
.Groupable()
.Filterable()
)
<script type="text/javascript">
function Grid_onError(args) {
if (args.textStatus == "modelstateerror" && args.modelState) {
var message = "Errors:\n";
$.each(args.modelState, function (key, value) {
if ('errors' in value) {
$.each(value.errors, function () {
message += this + "\n";
});
}
});
args.preventDefault();
alert(message);
}
}
function Grid_onDataBinding(e) {
var grid = $(this).data('tGrid');
if (grid.hasChanges()) {

e.preventDefault();
