c# – 更新Telerik Kendo Grid(MVC)后刷新

我有一个带有一些环境数据的Kendo Grid.网格的一个字段是“isDefault”,它接收1或0(对于真或假).在数据库中,我有一个触发器,当某个记录设置为isDefault = 1时,任何其他记录都更新为isDefault = 0,只是为了确保只有一个默认环境.

Kendo网格工作正常,它绑定数据并更新记录就好了但是在更新之后,网格没有刷新所有记录,如果有,比方说,记录1,isDefault = 1,我更新记录4到isDefault = 1触发器被触发并将所有其他记录更新为isDefault = 0但网格仍然显示记录1,现在记录4,isDefault = 1

这是我视图中的代码：

Html.Kendo().Grid<Models.Environment>()
                   .Name("environmentGrid")
                   .Sortable()
                   .ToolBar(tb =>  tb.Create())
                   .Editable(editable => editable.Mode(GridEditMode.PopUp))
                   .Columns(cols =>
                   {
                       cols.Bound(c => c.Name).Width(150).Sortable(true);
                       cols.Bound(c => c.ConnectionString).Width(150).Sortable(true);
                       cols.Bound(c => c.Template).Width(150).Sortable(true);
                       cols.Bound(c => c.isDefault).Width(150).Sortable(true);
                       cols.Bound(c => c.StatusID).Width(150).Sortable(true);
                       cols.Command(command => { command.Edit();}).Width(60);
                   })
                   .DataSource(ds => ds
                       .Ajax()
                       .Model(model => 
                       { 
                           model.Id(m => m.EnvironmentID);
                       })
                       .Read(r => r.Action("GetEnvironments","Admin"))
                       .Update(update => update.Action("UpdateEnvironments","Admin"))
                       .Create(update => update.Action("UpdateEnvironments","Admin"))                           
                   )

这是我的控制器上的代码：

[AcceptVerbs(HttpVerbs.Post)]
    public ActionResult UpdateEnvironments([DataSourceRequest] DataSourceRequest dsRequest,Environment environment)
    {
        environment.ModifiedBy = userName;

        if (environment != null && ModelState.IsValid)
        {
            if (environment.EnvironmentID != 0)
            {
                var toUpdate = xgr.EnviromentRepository.ListAll().FirstOrDefault(p => p.EnvironmentID == environment.EnvironmentID);
                TryUpdateModel(toUpdate);
            }
            xgr.EnviromentRepository.Save(environment);
        }
        return Json(ModelState.ToDataSourceResult());
    }

提前感谢您的回答.
