Bad Request when POST/Updating Sharepoint List Item

[Christian]

Hi,

 

I am trying to update Kendo Grid row inline, but getting a bad request when doing so. 

Reading from the list work just fine, but I am not able to update.

 

Any ideas?

var dataSource = new kendo.data.DataSource({
                transport: {
                    read: {
                        url: crudServiceBaseUrl + "?$top=2000",
                        type: "GET",
                        dataType: "json",
                        contentType: "application/json;odata=verbose",
                        headers: {
                            "accept": "application/json;odata=verbose"
                        }
                    },
                    // ...
                    update: {
                        url: function (data) {
                            return crudServiceBaseUrl + "(" + data.ID + ")";
                        },
                        type: "POST",
                        dataType: "json",
                        data: JSON.stringify({
                            "__metadata": { type: "SP.Data.MasterListItem" }
                        }),
                        contentType: "application/json;odata=verbose",
                        headers: {
                            "accept": "application/json;odata=verbose",
                            "X-RequestDigest": $("#__REQUESTDIGEST").val(),
                            "X-HTTP-Method": "MERGE"
                        },
                    },
                    //...
                    parameterMap: function (data, type) {
                        if (type == "update") {
                            for (var property in data) {
                                if (property != "__metadata")
                                    delete data[property];
                            }
                        }
                        return JSON.stringify(data);
                    }
                },
                error: function (e, data) {
                    console.log("Status: " + e.status + "; Error message: " + e.errorThrown );
                },
                pageSize: 15,
                schema: {
                    data: function (data) {
                        return data.d && data.d.results;
                    },
                    total: function (data) {
                        return data.d.results.length;
                    },
                    model: {
                        id: "Id",
                        fields: {
                            Id: { type: "number", editable: false, nullable: false },
                            Title: { type: "string", validation: { required: true } },
                            OWNER: { type: "string", validation: { required: false } }
                        }
                    }
                },
                //batch: false,
                //serverPaging: true,
                sort: { field: "OWNER", dir: "desc" }
            });

Hello,

Could you please share what is the exact response of the update request and specifically the error stored in the response? This will help us determine what might be problem. Also if possible share the signature of the Update method in the controller.
