禁用ASP.NET MVC验证

Question

I have a simple ViewModel class in my asp.net mvc application.

public class DestinationViewModel
{
     [Display(Name = "Country")]
     [some validation attributes]
     public string CountryName { get; set; }

     [Display(Name = "Destination")]
     [some validation attributes]
     public string DestinationName { get; set; }

     public DateTime? DepartureDate { get; set; }

     public DateTime? ArrivalDate { get; set; }
}

When i pass data to controller my application shows validation errors on invalid departure and arrival date. But i donnt want such behavior. Is there any way(attribute) to disable validation only on DepartureDate and ArrivalDate fields?

Answer 1

The MVC data binder will attempt to convert which ever value you put in your input field to it's corresponding ViewModel type. In your scenario, you are passing " 21321 " which obviously isn't going to work as it's not valid Date/Time.

Either pass a valid DateTime string value or leave it empty (as the field is nullable).

Tip - It's usually a good idea from a users point of view to make date fields readonly and provide a date picker of some sort to avoid issues with manually entering valid date formats.

If you want to write anything you want, then use string , not DateTime? or use one of this solutions:

• Disable validation on certain fields
• Disable Required validation attribute under certain circumstances
