Date range validation with Entity Framework 4 data annotations

Question

I am using Entity Framework 4 to provide the model for a ASP.NET MVC3 / Razor2 web application. I am using DataAnnotations to implement validation. I need to limit some dates to the range accepted by the SQL smalldatetime type.

My problem is that I can't get the RangeAttribute to work correctly for a date field. The model metadata definition for the field in question is:

    [Display(ResourceType = typeof(Resources.Patient), Name = "DateOfBirth_Name")]
    [DisplayFormat(DataFormatString = "{0:d}", ApplyFormatInEditMode = true)]
    [DataType(DataType.Date)]
    [Range(typeof(DateTime), "01/01/1900", "06/06/2079", ErrorMessageResourceType = typeof(Resources.Patient), ErrorMessageResourceName = "DateOfBirth_Range")] 
    public System.DateTime DateOfBirth { get; set; }

With this code, whatever value I put into the date field, it is treated as invalid by the application. In case its' relevant, I am using the JQuery-UI date picker with the field in question as well.

Can anyone help please?

You do not specify where the error occurs, but my guess is that it is client-side(?) jQuery Validation does not work well with the RangeAttribute. To verify, disable jQuery Validation and the valid input should pass the (server) validation.

To get around this you will have to write your own date range validation, e.g. http://blogs.msdn.com/b/stuartleeks/archive/2011/01/25/asp-net-mvc-3-integrating-with-the-jquery-ui-date-picker-and-adding-a-jquery-validate-date-range-validator.aspx

Alternatively you could look into packages such as Data Annotations Extensions or MVC Foolproof Validation to see if they could be used for solving the problem.
