In my UI if a user selects to allow multiple , he checks the check box next to “Multiple ”. When this check box is selected, “Maximum” option becomes enabled. Here user can define how many options can be done.
I want to allow my user to do “Infinite” . The option that I have decided to use for this thing is that if user does not type anything, “-” appears in edit box showing that there is not limit and “Unlimited” is allowed. Else user can type a number or user spin control in order to specify the limit up to he is allowed.
Option can be anything either using spin control or any other thing
unlimited
is also used in most torrent downloaders when setting upload and download speed. If that's too long you have∞
or∞
for the infinity symbol.
