A regular expression can certainly match what you're discussing:
/[0-9]+([0-9]{2})?/
but the "filter" regular expression matches each single character, not the
entire entered text, so no, it can't. You can expand on Gabriel's example,
which uses the filter and the changeValue event. If you set the "liveUpdate"
property to true, then the changeValue property will be fired on each key
press. (There is also an "input" event which is always fired on each key
press.) I don't think there's a way at this level to prevent the character
from being added to the field, so what you need to do is keep track of the
value of the field, and if the new character entered is not allowed, then
reset the field back to its previous value.
