Different validators in ASP.NET - ablealias/asp.net GitHub Wiki

There are the following two types of validation in ASP.NET:

• Client-Side Validation
• Server-Side Validation

Client-Side Validation:

When validation is done on the client browser, then it is known as Client-Side Validation. We use JavaScript to do the Client-Side Validation.

Server-Side Validation:

When validation occurs on the server, then it is known as Server-Side Validation. Server-Side Validation is a secure form of validation. The main advantage of Server-Side Validation is if the user somehow bypasses the Client-Side Validation, we can still catch the problem on server-side.

The following are the Validation Controls in ASP.NET:

• RequiredFieldValidator Control
• CompareValidator Control
• RangeValidator Control
• RegularExpressionValidator Control
• CustomFieldValidator Control
• ValidationSummary
