I have a number of fields I need to validate together. I need to check the sum of A+B+C = the sum of D+E.
If the sum of these two groups is not equal, I need to highlight all 5 fields. I can't seem to find a way to validate multiple properties together.
At FluentValidation rule for multiple properties , @Matías Romero suggests using something like
RuleFor(m => new {m.CountyId, m.Zip}).Must(x => ValidZipCounty(x.Zip, x.CountyId))
.WithMessage("Wrong Zip County");
This doesn't seem to highlight the invalid fields though. Is this possible with Fluent Validation (MVC5)?
