I am trying to make a textbox in UWP only allow the following input: 9 digits, followed by a '.' (optional), followed by 2 digits (optional), by using Regex. So far i have come up with an expression that allows 9 digits, or 9 digits and a '.' string pattern = @"^(?<Number>([0-9]{0,9})(\.?)([0-9]{0,2}?))"; I want it to accept 123456789 or 123456789.12 as inputs. But now it only accepts 123456789 or 123456789.
