B4J Question Efficient way to fill form data from jRDC2 call

[vfafou]

Hello!
Making a new desktop app, I'm trying to find an efficient way to fill dynamically EditText, Label, ComboBox and DatePicker objects of my forms.
So, I did the following steps:

1. I gave the exact database table field names as values to the Tags of the form objects.
2. I wrote a Sub to make a request to the jRDC2.
3. I wrote a Sub to fill dynamically the objects with database values.

The 3rd step is my question. Do you think that it's OK, or do you have to suggest another way?
The sub is the following:

Private Sub fillFormData(res As DBResult)
      
    For Each n As Node In pnlItems.GetAllViewsRecursive
      
        Private idx As Int = 0
      
        If n.Tag = "" Then Continue
      
        For Each col In res.Columns.Keys
          
            If n.Tag = col Then
              
                If n Is TextField Then
                    Private t As TextField = n
                    Private row() As Object = res.Rows.Get(0)
                    t.Text = utils.ifNull(row(idx),"")
                End If
          
                If n Is Label Then
                    Private l As Label = n
                    Private row() As Object = res.Rows.Get(0)
                    l.Text = utils.ifNull(row(idx),"")
                End If
              
                If n Is DatePicker Then
                    Private d As DatePicker = n
                    Private row() As Object = res.Rows.Get(0)
                    If utils.ifNull(row(idx),"") <> "" Then
                        d.DateTicks = row(idx)
                    Else
                        d.DateTicks = 0
                    End If
                End If
              
                If n Is ComboBox Then
                    Private c As ComboBox = n
                    Private row() As Object = res.Rows.Get(0)
                    c.SelectedIndex = utils.ifNull(row(idx),0)
                    c.Value = c.Items.Get(c.SelectedIndex)
                End If
              
                If n.Tag = "low_stock_alert_active" Then
                    swAlertStock.CheckState = utils.switchVal(swAlertStock, utils.ifNull(row(idx),"0"))
                End If
              
                If n.Tag = "next_order_alert_active" Then
                    swNextOrder.CheckState = utils.switchVal(swNextOrder, utils.ifNull(row(idx),"0"))
                End If
              
                If n.Tag = "discount_active" Then
                    swDiscountActive.CheckState = utils.switchVal(swDiscountActive, utils.ifNull(row(idx),"0"))
                End If
              
            End If
          
            idx = idx + 1
          
        Next
      
    Next
  
    txtCode.RequestFocus
  
End Sub

Thank you in advance!
