Kendo MVC Grid / Details Grid - child grid's controller not getting called

[Gaurav]

Does Id have to be an integer or it can be string?
It seems like in my case #=INVOICE# is getting value but it Read method to controller not sure why not getting called.

I tried looking at this example: http://demos.telerik.com/kendo-ui/grid/detailtemplate

    code:
    @(Html.Kendo().Grid<OpenInvoicesInfo>()
                  .Name("grid")
      .Columns(columns =>
      {
          columns.Bound(p => p.INVOICE).ClientTemplate("<input type='checkbox' value='#= INVOICE #' class='testclass' />").Width(4);
          columns.Bound(i => i.INVOICE).Width(15);
          ...     
      })
          .ClientDetailTemplateId("OrdersTemplate")
      .DataSource(dataSource => dataSource
          .Ajax()
          .PageSize(8)
          .Read(read => read.Action("GetOpenInvoices", "Maint", new { cust = Request.QueryString["cust"] }))
      )

    )

    <script id="OrdersTemplate" type="text/kendo-tmpl">
    @(Html.Kendo().Grid<CustomerComments>()
                                .Name("grid_#=INVOICE#")
                .Columns(columns =>
                {
                    columns.Bound(o => o.INVOICE).Width(15);
                    columns.Bound(o => o.Comment).Width(40);
                })
                .DataSource(dataSource => dataSource
                    .Ajax()
                    .PageSize(10)
                    .Read(read => read.Action("GetCustomerComments", "Maint", new { invoices = "#=INVOICE#" }))
                )
                .Pageable()
                .Sortable()
                .ToClientTemplate()
    )
</script>
          
        Controller:
        public ActionResult GetCustomerComments([DataSourceRequest] DataSourceRequest request, string invoices)
        {

            List<JNI.Enterprise.Contracts.CustomerComments> customer = InvoiceService.GetCustomerComments(invoices);

            return Json(customer.ToDataSourceResult(request));
        }

I will really appreciate if someone can reply.
Does it only work if it is in entity framework.
I am calling GetCustomerComments from a stored procedure.
It is loading the first grid fine but not calling details grid's controller method.

Hello Gaurav,

You can use whatever primitive you need for the details template. On my end the read method is called with both string and int ID in the overload of the action controller (respectively, in the modal too).

Are there any JS errors in the console? Does the request is at least sent (i.e., appears in the NET tab of the browser's dev toolbar)? It is possible to be called but for some reason not accessible (e.g., server-side error).
