What are validation controls in ASP.NET?
Validation controls in ASP.NET are used to ensure that user input is valid before processing it. They help in providing feedback to users.
Can you give me examples of different validation controls?
Sure! Common validation controls include RequiredFieldValidator, RangeValidator, RegularExpressionValidator, and CustomValidator.
How do I implement a RequiredFieldValidator?
To implement a RequiredFieldValidator, you need to add it to your ASP.NET page and set the ControlToValidate and ErrorMessage properties.
What happens if the validation fails?
If validation fails, the user will see the error message specified in the validation control, and the form will not be submitted.
