Hello,

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.

Restrict text input

Curious the best way to go about this. I want to restrict a text input to a specific length, must be 6 characters (no more, no less), and each position is restricted to certain characters. For example, the first position can only have C,E,F,G,V. The 2nd-6th will have similar restrictions. I’m assuming I will use the key press event? Anyone have any additional tips or help? Thanks in advance.
