I am using data annotations with MVC2 to validate a date of birth. The date of birth has 3 different fields. (Month, Day and Year) (they have to be three individual fields)
Right now I have individual data annotations for each field. How can I make it so that all three fields are validated and show one error message in my view. The setup I have right now creates an error message for each field.
If any one of those fields throws an error, I want to show a generic error message like "Date of Birth invalid".
Month Field:
[Required]
[DisplayName("Month")]
public IEnumerable<string> Months
{
get
{
if (_Months == null)
{
List<string> months = new List<string>();
months.Add("-- Select Month --");
months.AddRange(DateTimeFormatInfo.CurrentInfo.MonthNames.Select(Month => Month).ToList());
months.RemoveAt(months.Count - 1);
_Months = months;
}
return _Months;
}
set { _Months = value; }
}
private IEnumerable<string> _Months;
public string SelectedMonth {get; set;}
Day Field:
[Required]
[DisplayName("Day")]
[Range(1,31, ErrorMessage = "Not a valid day")]
public int? Day { get; set; }
Year Field:
[Required]
[DisplayName("Year")]
[Range(1900,9999, ErrorMessage = "Not a valid year")]
[ValidateBirthYear]
public int? Year { get; set; }
