MVC.NET Display error messages

Question

I have a model and have the following code in it:

public class Student
{
public int StudentId { get; set; }

[Required(ErrorMessage = "*")]
[Range(0, 100, ErrorMessage = "Value must be less than 100")]
public int Score { get; set; }
}

I want to add another error message to the Score property. Right now, it displays the message 'value must be less than 100' if a value greater than 100 is entered. But i also want to add an error message that says "the entered value must be greater than 25. I understand that i can change the Range from 0-100 to 25-100, but is there a way i can display a different error message if a value below 25 is entered?

Why not just "The value must be between 25 and 100"?. Otherwise you will need to write our own Minimum and Maximum attributes that derive from `ValidationAttribute` and inherit `IClientValidatable` — , Dec 21 '14 at 21:15

You can do this:

<script>
        function CheckNumber() {

            var number = 50;
            var msg = '';
            var isValid = true;

            switch (true) {

                case (number > 60):
                    msg = "Greater than 60";
                    isValid = false;
                    break;

                case (number > 40):
                    msg = "Greater than 40";
                    isValid = false;
                    break;

                case (number > 20):
                    msg = "Greater than 20";
                    isValid = false;
                    break;
            }

            if (!isValid) {
                alert(msg);
                return false;
            }

            return true;
        }
    </script>
