I need to validate 2 dates: "begin date" and "end date". "Begin date" must from today to the future and "end date" must be equal or greater than "Begin date". How can I do it with Data Annotations? Is it possible?

I have this custom validation attribute: public class MyDate1Attribute : ValidationAttribute { public override bool IsValid(object value) { DateTime d = Convert.ToDateTime(value); return d >= DateTime.Today; } } but I get this error: Error 1 'Dominio.elm' does not implement interface member 'System.ComponentModel.DataAnnotations.IValidatableObject.Validate(System.ComponentModel.DataAnnotations.ValidationContext)' C:\Users\baptista_l1\Documents\visual studio 2012\Projects\ELM2\Dominio\elm.csLuís Baptista– Luís Baptista2015-03-02 11:35:20 +00:00Commented Mar 2, 2015 at 11:35

You can do this with DataAnnotations as mentioned in bellow links:
- Greater Than or Equal To Today Date validation annotation in MVC3
- MVC Validation Lower/Higher than other value
- mvc4 data annotation compare two dates
- MVC custom validation: compare two dates
But, as an advice, solve this via Javascript libraries that are more easy than DataAnnotations like Jquery Input Mask

Client-side Validation (like Jquery input Mask) is great, but always check server-side too .. ( stackoverflow.com/a/15855799/130420 )
