You could, do something like this in your page load

If Page.IsPostBack Then
        Dim li As ListItem
        Dim oControl As Control

        For Each li in pytania_list.Items
                For Each oControl In li.Controls
                        If TypeOf Control Is RadioButtonList Then
                                ' Do Something.
                        End If
                Next
        Next

End If

Hope this helps,
