HellO!
I have some ajax on client side. It looks like


  $.ajax({
                                        cache: false,
                                        type: "POST",
                                        url: "@(Url.Action("AddShipmentRestriction", "ShipmentRestrictions"))",
                                        data: postData,
                                        success: function(data) {
                                            var grid = $("#newsletter-subscriptions-grid").data('kendoGrid');
                                            grid.dataSource.read();
                                        },
                                        error: function(xhr, ajaxOptions, thrownError) {
                                            alert('Failed to add record.');
                                        }
                                    });

And on a method on controller i have


f (r != null)
            {
                return Json(new { Result = false }, JsonRequestBehavior.AllowGet);
            }
            else
            {
                    var shipmentRestrictionRecord = new ShipmentRestrictionsRecord()
                    {
                        ShipmentMethodId = shippingMethod.Id,
                        StateProvinceId = stateproviceId
                    };

                    _shipmentRestrictionsService.Add(shipmentRestrictionRecord);
                }

                return Json(new { Result = true }, JsonRequestBehavior.AllowGet);
            }

So true result reread my grid and its fine. But on false i want to see this notification from ajax but I don't!
Could u please tell me why?

You should handle it on success function


  $.ajax({
                                        cache: false,
                                        type: "POST",
                                        url: "@(Url.Action("AddShipmentRestriction", "ShipmentRestrictions"))",
                                        data: postData,
                                        success: function(data) {
                                             
                                            // do something here depending on true or false

                                            var grid = $("#newsletter-subscriptions-grid").data('kendoGrid');
                                            grid.dataSource.read();
                                        },
                                        error: function(xhr, ajaxOptions, thrownError) {
                                            alert('Failed to add record.');
                                        }
                                    });
