How to add a minus sign with float regular expression

Hi there i am using
^(?:\d{1,2})?(?:\.\d{1,2})?$

Open in new window

to restrict the users to enter number and floats only. How can i add the minus sign(-) in the beginning of the expression so that it accepts the negative numbers like -35.01, -35

kindest regards

Why not just use
Double.TryParse()
with the number instead. That way if your app is used in another culture/country where -1.357,53 is normal instead of -1,357.53 it will still correctly evaluate it.
