problem datasource with serverGrouping and grid

[Mathieu]

Hello,

I have a problem to work the serverGrouping in my datasource and the kendo grid (download my project). 

this is my json result request : 

{"data":[{"toto":2,"name":"la valeur de i0"},{"toto":2,"name":"la valeur de i1"}],"count":1,"groups":[{"field":"toto","value":"2","items":[{"toto":2,"name":"la valeur de i0"},{"toto":2,"name":"la valeur de i1"}],"hasSubgroups":false,"aggragates":{}}]}

and this my javascript : 

var source = new kendo.data.DataSource({

            type: "jsonp",

            transport: {

                read: "Home/GetResult"

            },

            schema: {

                groups: "groups",

                total: "count",

                model: {

                    fields: {

                        toto: { type: "number" },

                        name: { type: "string" }

                    }

                },

                data: "result"

            },

            serverGrouping: true

        });

 

        $(document).ready(function () {


            $("#grid").kendoGrid({

                dataSource: source,

                height: 250,

                groupable: true,

                columns: [{

                    field: "toto",

                    title: "toto",

                    width: 100

                },

                {

                    field: "name",

                    title: "name",

                    width: 100

                }

            ]

            });

        });

but I have an error => SCRIPT5007: Unable to get value of the property 'length': object is null or undefined 

what's wrong with my kendo grid or my configuration ?

Thank you

Hello,

yes, in fact, I did not need the jsonp. 

I use the json and it's ok.

I hope that it will be able to help you,
