Is it possible to use Data Annotations for MVC in

问题:

How can I use this convention in an asp.net WEBFORM Business object class?

Example In MVC

using System.ComponenModel.DataAnnotation;

public class Customer
{
    [Required]
    [StringLength(5,20)]
    public string FirstName { get; set;}

    [Required]
    [StringLength(5,20)]
    public string LastName { get; set;}
}

I want to use this data annotation in my asp.net webform businessobject class for client validation and server validation.

Unfortunately WebForms doesn't have native support of Data Annotations like MVC.

But you can use custom decisions:

1. system componentmodel dataannotations for asp.net webforms

2. Building an ASP.NET Validator Using Data Annotations

3. ASP.NET: WebForms Validation with Data Annotations
