OOPs.. I Don't have to do it again

Sometimes you need to validate your ASP.net web form user input for numeric values.. The following works for me Any integer, positive or negative ^[-+]?[0-9]*$ Validates -9 9 12 1352345234 –3434134 +34 Does not validate -9.6 +89.9 Any decimal/float value Being: positive or negative, specified maximum length, limited number of decimals ^[-+]?\d{0,12}(\.\d{1,2})?$ Validates 123456789012.34 -123456789012.34 +123.45 D0es not validate 1234567890123 1234.123
