I tried your suggestion Alexander, but the error was not trapped at the time the model was changed. The validation is apparently only done when the SaveChanges() function is called.

This was the code I used:

MemberDetail mbr = new MemberDetail();
try
{
mbr.EmailAddress = "thisIsNotAnEmailAddressAndItIsTooLongAnywaySoItShouldCauseAProblemForTwoReasons";
}
catch (System.ComponentModel.DataAnnotations.ValidationException ex)
{
ViewBag.errorMessage = ex.Message;
//throw;
}

The MemberDetail object contains the following definition for EmailAddress:

[Display(Name = "Email Address")]
[DisplayFormat(ConvertEmptyStringToNull = true)]
[EmailAddress]
[StringLength(64, ErrorMessage = "The email address can be up to 64 characters long.")]
public string EmailAddress { get; set; }
