Listbox cell number format

is it possible to set a number format of a listbox cell ?
if not, can I set it in a way so the user can only enter numbers ?

now the title is right

For display., if the format does not change you can format the string when you enter the data.

For editing I think setting the Mask of the activeCell property in CellGotFocus event might work.

Hmm… I Just got another thought… I wonder if it is possible to AddHandler for the ActiveCell events and that be persistent.

No time to try that now but it could open up a very flexible way deal with input in a listbox.

thanks, will try it
