Hi
Use regular expression.
Its easy to use and u can define for it custom validating
but if ur data is sensitive validate it on ur business layer.
good luck

In the JavaScript method that you are using to filter the user's input, you will have to grab the text from the TextBox and check for the cases of consecutive commas, dots, and single quotes. Regular expressions can really help with this but they aren't required (if the last letter in the TextBox is a comma, dot, or single quote, and the current key press is the same then don't allow it, otherwise allow it.)

@Blacky, I know your clever enough to figure this out for yourself you have the right tools. I use this Regular Expressions Reference and this Regular Expressions Tester whenever I have to use JavaScript Regexs.
