What are the best practices for using jQuery Validation with ASP.NET?

When using jQuery Validation with ASP.NET, it's important to ensure that your validation rules are clear and consistent. You should also leverage unobtrusive validation to keep your HTML clean.

Can you explain what unobtrusive validation is?

Unobtrusive validation is a method that allows you to add validation rules to your HTML elements using data attributes, rather than inline scripts. This keeps your markup cleaner and separates your JavaScript from your HTML.

How can I implement custom validation methods?

You can implement custom validation methods by using the jQuery Validator's addMethod function. This allows you to define your own validation logic and integrate it seamlessly with the existing validation framework.

Are there any performance considerations I should be aware of?

Yes, be mindful of the number of validation rules you apply, as too many can slow down form submission. Also, consider validating only when necessary, such as on form submission rather than on every input change.
