asp.net-mvc – Kendo ASP.NET MVC – 索引超出范围数据绑定

尝试将数据表绑定到Telerik Kendo Grid时,我收到以下错误：

指数超出范围.必须是非负数且小于集合的大小.

我已经关注了Telerik的示例项目,但在我的代码中,它似乎没有在’DataSource’的’Read’函数上失败：

.Read(read => read.Action(“Read”,“Events”))

我有ActionResult Read()当前返回null,只是因为我想看看它是否甚至使它成为该函数.此外,我已经介入,数据表返回正确的列和列名称.

任何帮助表示赞赏.

Events.cshtml

@model System.Data.DataTable

@{
    ViewBag.Title = "Events";
    Layout = "~/Views/_mainLayout.cshtml";
}

<p>Events</p>

@(Html.Kendo().Grid(Model)
    .Name("GridStatic")
    .Columns(columns =>
    {
        columns.Bound("ID");
        columns.Bound("EntryType");
        columns.Bound("EventDate");
        columns.Bound("EventData");
        columns.Bound("Source");
    })
    .Pageable()
    .Sortable()
    .Scrollable()
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()       
        .Model(model =>
            {
                model.Field("ID",typeof(int));
                model.Field("EntryType",typeof(DateTime));
                model.Field("EventDate",typeof(string));
                model.Field("EventData",typeof(string));
                model.Field("Source",typeof(string));
            })
        .Read(read => read.Action("Read","Events"))
    )
)

EventsController.cs

public class EventsController : Controller
{
    //
    // GET: /Events/

    public ActionResult Events(string sName)
    {
        EventReader ereader = new EventReader(sName);
        return View(ereader.ParseIntoTable(ereader.GetListOfEvents()));
    }

    public ActionResult Read([DataSourceRequest] DataSourceRequest request)
    {
        return null;
    }
}

更新::

这是堆栈跟踪,我不确定这是否有帮助.
