What kind of formatting do you need in the list box? Because Text box object is not going to give you the option to select. May be the better would be to format list box another way or use table box or straight table.
As has been said by the others above, a text box does not have the functionality to select data. To make selections use a listbox, a multibox, or a chart.
There are different ways you can format a listbox - Classic, radio buttons, check box etc.
Can you clarify what you are tring to do and why a listbox does not meet your requirements.
