I have a small MVC2 app that displays in two cultures: en-US and es-MX. One portion contains a user input for a date that is pre-populated with the current date in the Model.
When using en-US, the date field is displayed as MM/dd/yyyy and can be changed using the same format without causing any validation errors.
When using es-MX, the date field is displayed as dd/MM/yyyy, but when the date is edited in this format, the server-side validation fails with the message:
The value '17/05/1991' is not valid for The Date.
One of the first things that jumps out at me about that message is that it is not localized. Both the message itself (which I do not think I can control) and the Display Name of the field (which I can control and is localized in my code). Should be displaying in a localized format.
I have tried stepping through the code to see exactly where the validation is failing, but it seems to be happening inside some of the compiled MVC or DataAnnotations code that I cannot see.
Application details: IIS6, ASP.NET 3.5 (C#), MVC 2 RTM
Sample Model Code:
public class TestVieModel{
[LocalizedDisplayNameDisplayName("TheDateDisplayName", NameResourceType=typeof(Resources.Model.TestViewModel))]
[Required(ErrorMessageResourceName="TheDateValidationMessageRequired", ErrorMessageResourceType=typeof(Resources.Model.TestViewModel))]
[DataType(DataType.Date)]
public DateTime TheDate { get; set; }
}
Sample Controller Action Code:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Save(TestViewModel model) {
if(ModelState.IsValid) { // <--- Always is false when using es-MX and a date foramtted as dd/MM/yyyy.
// Do other stuff
return this.View("Complete", model);
}
// Validation failed, redisplay the form.
return this.View("Enter", model);
}
