What are the best practices for validation in ASP.NET MVC?
Some best practices include using data annotations, implementing custom validation attributes, and utilizing model binding.
Can you explain how data annotations work?
Data annotations are attributes you can apply to model properties to enforce validation rules, like [Required] or [StringLength].
What if I need more complex validation logic?
For complex validation, consider creating custom validation attributes or using the IValidatableObject interface.
How can I display validation messages in the view?
You can use Html.ValidationMessageFor() in your Razor views to display validation messages next to the relevant fields.
