Hello Joel,
Thanks 4 your support. Your code looks pretty simple that's why i deployed
it immediatelly but :-( i didn't mention that my DataList "pytania_list" is
also nested in another master DataList which is called "ankieta_list". So
following your e.g. i wrote:

Dim li As ListItem
        Dim oControl As Control
        dim ankieta_list as DataList = Findcontrol("ankieta_list")
        Dim item As DataListItem

        For Each item in ankieta_list.Items
           For Each oControl In item.Controls
                    If TypeOf oControl Is DataList Then

                            dim pytania_list as DataList = oControl
                            Dim pyt_item As DataListItem
                            Dim ctrl As Control
                                         For Each pyt_item in
pytania_list.Items

                                                For Each ctrl In
pyt_item.Controls

                                                        If TypeOf ctrl Is
TextBox Then

                                                            do somth...
                                                        end if
                                                 next
                                        next
                 End If
                next
        Next

... and it works !! :-)

Thanks a lot Joel !!
