}


var result = new DataSourceResult()
{
Data = productViewModels,
Total = allcount,
AggregateResults = null,
Errors = null,
};
return Json(result, JsonRequestBehavior.AllowGet);
}

这是我的代码。当我从动作服务器返回数据时，分页不起作用。我想做服务器分页kendo ui组网格，但响应数据类型未定义。我需要组网格的工作示例。它在基本网格中工作，但不适用于组网格。

您应该只需要更新控制器方法。由于您正在进行的排序似乎非常基本，您可以使用提供的Kendo方法ToDataSourceResult(DataSourceRequest request)。

将以下内容添加到Controller中的使用部分：

using Kendo.Mvc.Extensions;

然后简单地返回：

 return Json(productViewModels 
     .ToDataSourceResult(request, JsonRequestBehavior.AllowGet));

这应该为您处理任何过滤，排序，分组和分页。

您可能还想查看AutoMapper，以便更轻松地将对象从Product映射到ProductViewModel。
