Validation
| Topics in this section |
Validation is used to ensure that users supply all the information required on the form, and that the data entered meets specific formatting requirements. A field can have only one of each type of Validator; generally two will be enough to do proper data validation.
During Design time, the error messages will be shown under the fields to show what validation rules have been applied. During Runtime, the error messages will be hidden until required to enforce validation.
Form Master makes use of three of the Validators available in ASP.NET
- Required Field Validator
- Regular Expression Validator
- Compare Validator
Additionally Form Master also used a Checklist Validator Control and the Validator Summary Control.
Field Validation is important to ensure that clean consistent data is collected which can be used efficiently throughout the organization
