Thank you, Edward for your answer!
I start to "play" with dynamiccurrentcontrol as you suggested. It started to work as I wanted, except ..
So, something is still wrong, because it show the combobox on starting the form and if I change row on different field, than this one, which contains combobox. But if I change the row from the field containing the combobox, on the next row (up or down is equal) a text box will appear. (for a very short period the combobox appears)

Can you give me any suggestion?

TIA
