you can use regex provided in teamsite, you can specify the number of characters in your textarea validation-regex [0-4000]

use onSaveValid instead of onSave.... this event occures after onSave and once the form is validated.... It should work...

If you use this solution, please keep in mind that you need to set the Item as setValid as false and again to true onSave... along with setHighlightMode as true and false accordingly.

However, the validation regex option is simple and provided by iwov only.

Why didn't you search Forum before asking? This question had popped up so many times that Ghoti even bothered to assemble
a little cross-reference post to outline various solutions. Look here
