        @(Html.Kendo().Grid<TelerikAspNetCoreApp7.Models.OrderViewModel>()
                .Name("grid")
                .Columns(columns =>
                {
                    columns.Bound(p => p.OrderID).Filterable(false);
                    columns.Bound(p => p.Freight);
                    columns.Bound(p => p.OrderDate).Format("{0:MM/dd/yyyy}");
                    columns.Bound(p => p.ShipName);
                    columns.Bound(p => p.ShipCity);
                    columns.Command(command =>
                    {
                        command.Custom("Destroy")

@(Html.Kendo()
