max length on DoubleEditBox

I would like a way so that if the maximum value on the double edit box is about to be exceeded to not let the user type any more values into that field. So if the maximum property is set as 99 and the user types 123, all that would show in the box is 12. Also if the max was set at 89 and the user typed 99 all that would show is the 9.

Is there currently any way to do this? If not is there any way to just limit the characters that can be typed? I looked for a maxLength property and didn't find one.

Thanks.
