Hi,
need some help, this code works fine* with Chrome and Firefox, but i doesn't work with ie9.

e.errorThrown = No Transport
e.xhr.responseText = undefined.

* I can add and update items but i can't remove them.

Here is the code.

<div id="grid"></div>
$(document).ready(function () {
                var crudServiceBaseUrl = "http://localhost:11028/IntexService.svc/Zonas",
                 crudServiceOptions = "",
                    dataSource = new kendo.data.DataSource({
                        type: "odata",
                        transport: {
                            read: {
                                url: crudServiceBaseUrl + crudServiceOptions,
                                dataType: "json"
                            },
                            update: {
                                url: function (data) {
                                    return crudServiceBaseUrl + "(" + data.ZonaId + "L)";
                                }
                            },
                            create: {
                                url: crudServiceBaseUrl
                            },
                            destroy: {
                                url: function (data) {
                                    return crudServiceBaseUrl + "(" + data.ZonaId + "L)";
                                }
                            }
                        },
                        batch: false,
                        pageSize: 10,
                        serverPaging: true,
                        serverFiltering: true,
                        schema: {
                            model: {
                                id: "ZonaId",
                                fields: {
                                    ZonaId: { editable: false, nullable: true },
                                    Nombre: { validation: { required: true} }
                                }
                            },
                            errors: "Errors"
                        },
                        error: function (e) {
                            alert("La operaciĆ³n ha fallado: \n" + e.errorThrown + ": " + e.xhr.responseText);
                            this.cancelChanges();
                        }
                    });
 
                $("#grid").kendoGrid({
                    dataSource: dataSource,
                    filterable: true,
                    pageable: true,
                    height: 410,
                    toolbar: ["create"],
                    columns: [
                            { field: "Nombre", width: "150px" },
                            { command: ["edit", "destroy"], title: " ", width: "110px"}],
                    editable: "popup"
                });
            });
Any idea?
Thanks.

Hi Christian,


Basically in current scenario when the errors are contained in the JSON response from the server the xhr object will be empty (it's populated only when the Ajax request fails such as HTTP error). I would suggest to use the e.status and e.errorThrown properties from the event data instead.

Kind Regards,

I can't add 'DELETE' method...i dunno how.
Could u help me?

----------------------

Fixed:

Add DELETE  HttpContext.Current.Response.AddHeader() in Global.asax.

        
protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "*");
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS" )
            {
                //These headers are handling the "pre-flight" OPTIONS call sent by the browser
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods" , "GET, POST, PUT, DELETE" );
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers" , "Content-Type, Accept" );
                HttpContext.Current.Response.AddHeader("Access-Control-Max-Age", "1728000" );
                HttpContext.Current.Response.End();
            }
        }

Thanks
