Hierarchy grid missing Expand icon

[Charles]

Good day,

I'm using Server hierarchy Grid which containes a sub grid in DetailTemplate.

But there's no expend icon in the grid which data was loaded successfully. In page HTML codes, there's <td class="k-hierarchy-cell"> but style.display = 'none'

Please help to check.

Code and screenshot as below:

 

@{ Html.Kendo().Grid(Model)
        .Name("grid")
        .Columns(columns =>
        {
            columns.Bound(e => e.BookingNumber).Width(200);
            columns.Bound(e => e.QuotationId).Width(120).Title("QT#");
            columns.Bound(e => e.ProformaETD).Width(120);
            columns.Bound(e => e.BLShipper).Width(400);
            columns.Bound(e => e.BLConsignee).Width(400);
            columns.Bound(e => e.BLNotify1).Width(400);
            columns.Bound(e => e.BLNotify2).Width(400);
            columns.Bound(e => e.BLContractHolder).Width(400);
        })
        .DetailTemplate(item =>
        {
            Html.Kendo().Grid(item.Containers)
                    .Name("Ctn_" + item.BookingId)
                    .Columns(columns =>
                    {
                        columns.Bound(o => o.ContainerNumber).Width(150);
                        columns.Bound(o => o.ContainerType).Width(100);
                        columns.Bound(o => o.IsSOC);
                    })
                    .Pageable()
                    .Width(500)
                    .Render();
        })
        .Pageable()
        .Scrollable()
        .DataSource(dataSource => dataSource.Server().PageSize(20))
        .Sortable()
        .Height(650)
        .Render();
        }

Hello,

Could you check which stylesheet sets the display: none style in the "Styles" tab of the browser's devtools? Also please specify which version of UI for ASP.NET MVC you're using, and post the section of the _Layout.cshtml where the Kendo CSS files are loaded. We would like to check whether they are loaded in the correct order.
