I need a regular expression for a regular expression control that only allows numbers (any amount) to the left of decimal (if it needs a decimal) and then only 2 numbers to the right of the decimal.  They may or may not have a number and a decimal place.  But if they use a decimal place they can only input 2 numbers after it .

thanks in advance for the help.

^(?:\d+(?:\.\d{1,2})?)?$

If they must enter 2 numbers after the decimal--meaning they can't enter just one--then change {1,2} to {2}.
