Field Validations
NileDesk's Field Validations help maintain data integrity by enforcing rules on the information entered. Think of validations as vigilant guards that ensure all entered data follows predefined standards. These rules not only prevent errors but also enhance the reliability and trustworthiness of your data.
Different field types support different validation rules. Below is a comprehensive list of available validations and the fields they apply to.

| Max. Length | The field must not exceed a specified number of characters. | Text |
| Min. Length | The field must have at least a specified number of characters. | Text |
| Equal To | The field must match a static value or the value in another field. | Text, Number, Date, Drop Down, User, Data Snap, Data Link |
