Question

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，但是在我的代码中，似乎没有使用'DataSource'的'Read'功能：

。阅读（读取=＆gt; read.Action（“阅读”，“事件”））

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。

感谢任何帮助。

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;
    }
}

Answer 1

原来它与我的web.config有关。我在创建的每个Kendo对象中都遇到了错误。将以下代码添加到顶级web.config似乎可以解决所有问题。

<runtime>
  <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
    <dependentAssembly>
      <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
      <bindingRedirect oldVersion="1.0.0.0-4.0.0.0" newVersion="4.0.0.0" />
    </dependentAssembly>
  </assemblyBinding>
</runtime>

通过在解决方案中包含部分，web.config文件可以帮助您。

<runtime>
    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>

Answer 3

我推测错误正在发生，因为Read操作未返回有效的结果集。

通常，在Ajax模式下读取时，Kendo网格需要返回JsonResult。如果你返回一个空的DataTable格式正确的json结果，那么我怀疑它会修复它。

  public ActionResult Read([DataSourceRequest] DataSourceRequest request)
  {
     return this.Json(new DataTable().ToDataSourceResult(request));
  }

显然，您应该将DataTable替换为您的真实结果集。
