Question

我想在网格中显示已过滤的数据，但我不知道在monthYearfilter where子句之后它未显示的原因到底是什么原因。它使用currentmonthyear将数据绑定到kendo网格，但不使用monthYearfilter。我以前在不同的项目中使用了相同的功能，并且运行正常。

我确实在linq where子句之后获取DataSourceResult结果中的数据，但是没有在网格中显示。

//控制器代码

[HttpPost]
    public ActionResult BillingChecklist_Read([DataSourceRequest]DataSourceRequest request,string monthYearfilter)
        {


        using (var preemploymentdata = new AREntities())
        {
            IQueryable<BillingCheckList> preEmploymentWorkflows = preemploymentdata.BillingCheckLists;


            DataSourceResult result;




            if (monthYearfilter != null)
            {

                result = preEmploymentWorkflows.Where(x => x.MonthYear == monthYearfilter).ToDataSourceResult(request);
            }
            else  
            {

                 string currentmonthyear = DateTime.Now.Year + "/0" + DateTime.Now.Month;

                 result = preEmploymentWorkflows.Where(x => x.MonthYear == currentmonthyear).ToDataSourceResult(request);
            }



            return Json(result);


        }
    }

由于您要过滤数据服务器端，请在返回DataSourceResult之前尝试清除过滤器，以防止数据在客户端再次被过滤。

result.Filters.Clear();

return Json(result);

在使用linq的where子句之后在Kendo Grid中显示DataSourceResult
