you didn't say why or what is not working properly! This one-line code seemed to return a response of "false" even if a single integer was entered. it's been a while since I've coded, but I'm unfamiliar with this syntax.

For example if you want A-Z, then the range is [65, 90], and a-z is [97, 122]does not work in either Chrome or Firefox.
You may be referring to submission validation of non-numeric characters, which does work properly with HTML5.
The original question, however, was interested in preventing the non-numeric entry entirely.
I am trying to validate the entry of a decimal number in a textbox.The user can enter .25, 0.25, 1.25, and so on, with either a leading zero or not and only one decimal place.I have seen a few solutions that work with either no leading zero or with only one decimal place, but not both. Thanks for your help, but check For Second Decimal doesn't work when there is already a number with a decimal point in the textbox.This paper introduces these new controls and discusses tips and tricks on working with them in practical scenarios.(34 printed pages) Introduction Looking at Validation The Required Field Validator Control The Compare Validator Control The Range Validator Control The Regular Expression Validator Control The Custom Validator Control The Validation Summary Control Conclusion In your studies of ASP.
