1. Data Annotation makes it easy to validate your model.
2. Most of the time we implement the validation at server side, i.e. the form is posted to the server and if the model is invalid the response is sent back to the client and user is displayed with error messages.
3. The same feature can be achieved at client side that means the form will be validated at client side, before it is posted to the server.
4. If the form validation passes, the form is posted otherwise the error message is shown.
5. In this video we will see how to enable the client side validation.
