the currency required format looks
1,100,258 100,258 23,258 3,258 or integers 123456 or 2421323 , on.
i type below in validationexpression
(^[0-9]{1,3}(,\d{3})*) | (^[0-9][0-9]*) but doesn't work.
do have ignore pattern whitespace on? if not, remove 2 spaces on each side of pipe.
since you're trying match either, should stick marker $ @ end of string, so
also point of ^[0-9][0-9]*, when can use ^[0-9]+?
^([0-9]{1,3}(?:,\d{3})*|[0-9]+)$ or
^(\d{1,3}(?:,\d{3})*|\d+)$ explanation:
^ # anchors beginning string. ( # opens cg1 \d{1,3} # token: \d (digit) (?: # opens ncg , # literal , \d{3} # token: \d (digit) # repeats 3 times. )* # closes ncg # * repeats 0 or more times | # alternation (cg1) \d+ # token: \d (digit) # + repeats 1 or more times ) # closes cg1 $ # anchors end string.
