Identify Special Characters in Text Feild

Hello,

Is there any way to identify Special characters entered in the text field, and same thing i need to display the message saying “Special Characters are not Allowed”.

Thanks,
Sunil

Since “special characters” means different things to different people and in different contexts, there’s no one answer. The simplest solution is to use a validation expression to identify acceptable characters. A regexp like this:

[a-zA-Z][a-zA-Z0-9 _]*

will allow only spaces and alphanumerics and underscores, but starting with a letter.

Edit: this is part of the FormattedTextField:

Here’s an example that may help you.
