用ajax如何绑定KendoUI Grid  传送数据

这是我前台代码

$(function () {
            $("#grid").kendoGrid({
                dataSource: {
                    transport: {
                        dataType: "json",
                        read: "/KendoUI/Index"
                    },
                    pageSize: 5,
                },
                pageable: {
                    refresh: true,
                    pageSizes: true,
                    buttonCount: 5
                },
                columns: [{
                    field: "Stu_Id",
                    title: "学生编号",
                    width: 200
                }, {
                    field: "Stu_Name",
                    title: "学生姓名"
                }, {
                    field: "Stu_Age",
                    title: "学生年龄"
                }, {
                    field: "Stu_Class",
                    title: "所属班级"
                }]
            });
        });

后台动作方法就这样

public ActionResult Index([DataSourceRequest]DataSourceRequest request)
        {
            return Json(manager.getAll(),JsonRequestBehavior.AllowGet);   　　　　                 //manager.getall()是调用的业务层的方法
        }
