The type of characters that are allowed to be added to the string.
Note that the character validation does not validate the entire string as being valid or not. It only does validation on a per-character level, resulting in the typed character either being added to the string or not.
| None | No validation. Any input is valid. |
| Integer | Allow whole numbers (positive or negative). |
| Decimal | Allows decimal numbers (positive or negative). |
| Alphanumeric | Allows letters A-Z, a-z and numbers 0-9. |
| Name | Only allow names and enforces capitalization. |
| EmailAddress | Allows the characters that are allowed in an email address. |
