How does ASP.NET MVC remote validation work?
ASP.NET MVC remote validation allows you to validate user input on the server side without a full page refresh. It sends an AJAX request to the server to check if the input is valid.
Can you show me an example of how to implement it?
Sure! You can use the [Remote]
attribute in your model. For example: [Remote(action: "ValidateUsername", controller: "Account")]
.
What happens if the validation fails?
If the validation fails, the server returns an error message, which is displayed next to the input field, allowing users to correct their input.
Is it possible to customize the error message?
Yes, you can customize the error message by using the ErrorMessage
property in the [Remote]
attribute.
