This question has to have been asked before, but I think the search terms are too generic for me to find the answer I’m looking for, so I’ll ask it again.

I have a model with an int property, and a range annotation.

If the user enters something other than an int, the validation message responds with The value '<bad data>' is not valid for '<property name>'… which is great, but I want to provide a bit more feedback, i.e., Expecting an integer value in this field..

Since this validation fails before the other validators take a look, I don’t know how (or if it’s possible) to override the default validator message for this.

What are my options?

per request, I am posting the code, but there’s not a lot to it:

[Range(0,65535, ErrorMessage="Port must be between 0 and 65535.")] 
public int Port { get; set; }

There is validation that occurs before it reaches the RangeAttribute. I want to replace the default message with one of my own choosing.

    If you’re using standard annotations, you should be able to override the error message with something like this:

    [MyAnnotation(...., ErrorMessage = "My error message")]
public int myInt { get; set; }

    Or do you actually want to append to the default error message instead of replacing it (not clear in question)?

    Update: Misread — suggest this as the answer: How to change the ErrorMessage for int model validation in ASP.NET MVC? or better yet How to change 'data-val-number' message validation in MVC while it is generated by @Html helper
