MVC Dataannotations - Only validate on Form Submit

I need to validate the form only when I click the submit button and present the Error Messages based on the DataAnnotation's properties.

ViewModel:

 [Required(ErrorMessage = "Field Required")]
 [RegularExpression(@"^.{5,}$", ErrorMessage = "Message is to short")]
 public string Message { get; set; }

HTML:

 @Html.TextAreaFor(m => m.Message)
 @Html.ValidationMessageFor(m => m.Message)

What happens is that when I submit the form with an empty Message, I get the "Field Required" message, but when I start writing in the field, the error message change to "Message is to short" but I only want this when I press the submit button again.

// Disable keyup validation on key up
var validator = $("#yourFormId").data("validator");
if (validator)
    validator.settings.onkeyup = false;
