Hierarchy - Add New Record doesn't show for child

[Elliott]

I'm trying to create a RadGrid - and only to parent columns show Add New Record
I put a CommandItemDisplay in the GridTableView, set up the right ParentTableRelations

Protected Sub rgSpiffDetail_NeedDataSource(ByVal source As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rgSpiffDetail.NeedDataSource
    Dim VendorID As Integer = 0
    Dim ds As DataSet = Nothing
    Dim dt As DataTable = Nothing

    If rcbVendors.SelectedValue = String.Empty Then
        VendorID = Quicksilver_VendorID
    Else
        VendorID = rcbVendors.SelectedValue
    End If
    Dim ws As New CommonFunctions
    If e Is Nothing Then
    ElseIf e.IsFromDetailTable Then
        Exit Sub
    End If
    ds = ws.GetSpiffs(VendorID)
    If ds.Tables.Count > 0 Then
        dt = ds.Tables(0)
    End If
    rgSpiffDetail.DataSource = dt
End Sub

Protected Sub rgSpiffDetail_DetailTableDataBind(ByVal source As Object, ByVal e As Telerik.Web.UI.GridDetailTableDataBindEventArgs) Handles rgSpiffDetail.DetailTableDataBind
    Dim gdItem As GridDataItem = Nothing
    Dim SpiffID As Integer = 0
    Dim ds As DataSet = Nothing
    Dim dt As DataTable = Nothing

    gdItem = CType(e.DetailTableView.ParentItem, GridDataItem)
    SpiffID = CInt(gdItem.GetDataKeyValue("SpiffID"))
    Dim ws As New CommonFunctions
    ds = ws.GetItemsforSpiff(SpiffID)
End Sub

Protected Sub rcbVendors_SelectedIndexChanged(ByVal o As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs) Handles rcbVendors.SelectedIndexChanged
    Dim ea As Telerik.Web.UI.GridNeedDataSourceEventArgs = Nothing
    rgSpiffDetail.Rebind()
End Sub

and the code behind
