Ders oluştur 函数必须像我在插入后忘记刷新网格 

 [AcceptVerbs(HttpVerbs.Post)]
    public JsonResult DersOlustur([DataSourceRequest] DataSourceRequest request, Ders model)
    {
        if (model != null && ModelState.IsValid)
        {
           Helper.Islemci.DersTanimla(model);
        }
        return Json(new[] { model }.ToDataSourceResult(request, ModelState));
    }

将此添加到您的列中，它将起作用：

columns.Bound(p => p.Id); // ID is the ID of the view model of course; i.e.,  your ID (primary key col.)

发生的情况是，当您单击更新时，它不知道应该使用哪个 ID 进行更新，结果就是将整个视图模型带入更新操作方法，这当然是所有你的行..

您不必显示 id 列，但它必须存在。

所以上面可以做成这样：

columns.Bound(p => p.Id).Visible(false);

这对我有用。
