telerik grid detailtview Razor vb.net Syntax - razor

Question

I need some help with the syntax
I have the Razor code below. But I do not get the detail view ok. When I use the code below the detail grid will be rendered and after that the normal customer grid. The object is a customer and a detail view are some settings for this customer? Can someone help me with the syntax?
Thanks!
#(Html.Telerik.Grid(Model) _
.Name("CustomerGrid") _
.DataBinding(Function(dataBinding) dataBinding.Server() _
.Update("SaveCustomer", "Admin")) _
.DataKeys(Function(keys) keys.Add(Function(o) o.CustomerID)) _
.DetailView(Function(dt) dt.Template(Sub(tt)
Html.Telerik.Grid(tt.MessageSettings) _
.Name("MessageSetting" & tt.CustomerID) _
.Columns(Function(dc) {
dc.Bound(Function(dd) dd.CustomerMessageSettingsID), _
dc.Bound(Function(dd) dd.Free)
}).Render
End Sub)) _
.Columns(Function(c) { _
c.Bound(Function(o) o.CompanyName).Width(200), _
c.Bound(Function(o) o.Credits), _
c.Bound(Function(o) o.Address), _

I recommend you to use LoadContentFrom()
.DetailView(details => details.ClientTemplate(
Html.Telerik().TabStrip()
.Items(items =>
{
items.Add().Text("MyView").LoadContentFrom("PartialActionResult", "Controller", New With { _
.param1 = "<#= ID#>" _
})
}) // End of item Tabs
.ToHtmlString()
) // End of Detail View Client Template
) // End of Detail View
