CRUD Kendo，批量更新网格返回数据为空

Question

我有这个架构，

  schema: {
                    data: "d.Data", // web methods return JSON in the following format { "d": <result> }. Specify how to get the result.
                    total: "d.Total",
                    model: {

在运输中：

update: {
                            url: "VisorEuroProv.aspx/Update", //specify the URL which should create new records. This is the Create method of the Products.asmx service.
                            contentType: "application/json; charset=utf-8", // tells the web method to serialize JSON
                            type: "POST" //use HTTP POST request as the default GET is not allowed for web methods
                            //complete: function(e) {  $("#grid").data("kendoGrid").dataSource.read()} 

                        },

和WebMethod

 [WebMethod]
    public static void Update(IEnumerable<dtoVisorEuroProveedores> dtoVisorEuroProveedores)
    {...}

更新正常，但没有关闭BatchEdit，显示javascript错误：未捕获TypeError：无法读取属性'Data'为null

Answer 1

最后，我返回IEnumerable< myObject >变量的List（）。
