Kendo UI MVC，Grid使用Data方法查看其他数据无法正常工作

Question

我在razor视图中有以下kendo Grid

@(Html.Kendo().Grid<PO>()
  .Name("manualMatchGrid")
  .Columns(columns =>
      {
          BindFields(columns);
      })
    .Selectable(s => s.Mode(GridSelectionMode.Multiple))
    .Pageable()
    .Sortable()
    .DataSource(dataSource =>
        dataSource.Ajax()
            .Batch(true)
            .PageSize(20)
            .ServerOperation(false)
            .Model(model =>
            {
                model.Id(l => l.Id);
            })
            .Read(read => read.Action("ReadInvoicePOs", "Invoice", new { invoiceID = ViewBag.InvoiceID }).Data("getInvoicePOsFilterData"))
    )
    .Pageable()
    .Navigatable()
)

和getInvoicePOsFilterData javascript函数......

<script>
function getInvoicePOsFilterData() {
    return {
        pONumber: $('#PONumber').val(), vendorId: $('#VendorId').val(), clientId: $('#ClientId').val()
    };
}
</script>

查看chrome网络检查器......

Data InvoiceId，即routeData，没有发送任何内容。我错过了什么。

编辑：

...控制器

[AcceptVerbs(HttpVerbs.Get)]
public JsonResult ReadInvoicePOs([DataSourceRequest]DataSourceRequest request, int invoiceId, string pONumber, int? vendorId, int clientId)
    {
        var pOs = dynamicPOManager.GetPOs(invoiceId, clientId, pONumber);

        DataSourceResult result = pOs.ToDataSourceResult(request);
        return Json(result, JsonRequestBehavior.AllowGet);
    }

我发现了问题。问题是POST是Read方法的默认值。我添加了“Type（HttpVerbs.Get）”，它运行得很好。

.Read(read => read.Action("ReadInvoicePOs", "Invoice", new { invoiceID = ViewBag.InvoiceID }).Data("getInvoicePOsFilterData").Type(HttpVerbs.Get))
