ASP .NET MVC 3 Data Annotations GreaterThan LowerThan for DateTime and int

Question

I would like to know what is the easiest way to have a \"Greater Than\" & \"Lower Than\" validation on a ASP.NET MVC 3 form?

I use unobtrusive JavaScript for client

Answer 1

You can use the DateGreaterThanEqual attribute in your model. Here is a snippet of code that I used to validate two fields in my form.

[DataType(DataType.Date)]
[DisplayName("From Date")]
public DateTime? StartDate { get; set; }

[DataType(DataType.Date)]
[DisplayName("To Date")]
[DateGreaterThanEqual("StartDate")]
public DateTime? EndDate { get; set; }
