With the code that follows, I am able to edit any record, but I cannot add a new record.  The popup window never appears and I get a javascript error "0x800a1391 - JavaScript runtime error: SupplierLocation is undefined".  

(grid code)

@(Html.Kendo().Grid<FastTrack.MVC.Models.ContractorLoadTicketModel>().Name("gridUnreconciledContractor").Columns(c =>
        {
            c.Bound(m => m.SupplierLocation).ClientTemplate("#= SupplierLocation.SupplierName #").Title("Supplier");
            c.Bound(m => m.SupplierLocation.LocationName).Title("Origin");
            c.Bound(m => m.TicketNumber).Title("Ticket #");
            c.Bound(m => m.ReceivedDate).Title("Date").Format("{0:MM/dd/yy}").HtmlAttributes(new { style = "text-align:right" });
            c.Bound(m => m.ProjectMaterial.MaterialName).Title("Material");
            c.Bound(m => m.Hauler.HaulerName).Title("Hauler");
            c.Bound(m => m.TruckNum).Title("Truck #").Width(75)
                .ClientFooterTemplate("Loads: #=count#")
                .FooterHtmlAttributes(new { style = "text-align:right" });
            c.Bound(m => m.Quantity).Title("Quantity").Format("{0:n2}").HtmlAttributes(new { style = "text-align:right" })
                .ClientFooterTemplate("Total: #=kendo.toString(sum, 'n2') #")
                .FooterHtmlAttributes(new { style = "text-align:right" });
        })
        .DataSource(d => d
            .Ajax()
            .ServerOperation(false)
            .Read(read => read.Action("GetUnreconciledContractorTickets", "TicketReconcile").Data("paramProjectKey"))
            .Create(update => update.Action("SaveTicket", "TicketReconcile"))
            .Update(update => update.Action("SaveTicket", "TicketReconcile"))
            .Destroy(update => update.Action("DeleteTicket", "TicketReconcile"))
            .Events(events => events.Sync("contractorTicketSaved"))
            .Aggregates(a =>
                {
                    a.Add(m => m.TruckNum).Count();
                    a.Add(m => m.Quantity).Sum();
                })
            .Model(model => model.Id(m => m.TicketKey))
        )
        .ToolBar(toolbar =>
        {
            toolbar.Create();
        }

(model)

public class ContractorLoadTicketModel
    {
        public int TicketKey { get; set; }
        public int ProjectKey { get; set; }

Hi,

The error would be thrown because of this column template:
c.Bound(m => m.SupplierLocation).ClientTemplate("#= SupplierLocation.SupplierName #").Title("Supplier");
The SupplierLocation object will be null by default for new items so you should either set a default value with the DataSource Model:
.Model(model =>
    {
        model.Id(m => m.TicketKey)
        model.Field(m => m.SupplierLocation).DefaultValue(new SupplierLocation());
    })
or check if the object is not null in template before accessing its fields:
#= data.SupplierLocation ? SupplierLocation.SupplierName : '' #
