ASP.NET MVC ModelState IsValid - How to exclude specific properties from validation?

I'm a nub in MVC.I've a Model:

    public class Usuarios
    {

     [Required(ErrorMessage = "**TxtOPID is required")]
        public string TxtOpID
        {
            get { return this.txt_opId; }
            set { this.txt_opId = value; }
        }

     [Required(ErrorMessage="**Password is required")]
        public string TxtPassword
        {
            get { return this.txt_password; }
            set { this.txt_password = value; }
        }

        [Required(ErrorMessage="**Email is required")]
        [RegularExpression("^[a-z0-9_\\+-]+(\\.[a-z0-9_\\+-]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)*\\.([a-z]{2,4})$",ErrorMessage="**Invalid email")]
        public string TxtEmail
        {
            get { return this.txt_email; }
            set { this.txt_email = value; }
        }
}

This is DataAnnotations and works fine when i try to check if all properties are valid with ModelState.IsValid propertie.

The problem is when i dont want to check ALL properties.i.e: If i want to check only TxtOPID and TxtSenha propertie,like in a Login form,where only OPID and Password are required.

How can i exclude Email propertie validation,in a specific Action in a controller?

I tried:

  public ActionResult SignIn([Bind(Exclude="TxtEmail")]Usuarios usuario)
  {
    [...]
  }

But it doesn't work,its always INVALID cause,TxtEmail is not required for that specific form.

Any ideias?

Don't put all of your validation in a single class. Build a class for Login, and another one for Contact, etc.

Basically each model will have DataAnnotations to validate that model.. even if you have 30 different ones. You can always create a Base Class and put common properties in there and simply inherit from it.

In my situation I have a login form and the Class (using DataAnnotations) validates "UserName" and "Password". I also have an "Events" form that requires the event name, date, time, etc. So I have another Class for validating events.
