    <p>This is my model.</p> <pre><code>public class MyModel { [Display(Name = "Email Address")] [EmailAddress] // my custom validator to check valid email format [Remote("IsEmailAddressUsed", "Validation")] public string EmailAddress { get; set; } } </code></pre> <p>The problem I have is that the IsEmailAddressUsed action gets called even when I enter an invalid format for email address. The custom EmailAddress validator works fine when I remove the Remote one. I want to check against the DB only when the email address is in a correct format. Is there a way to make the Remote validator evaluated last?</p> <p>The implementation of the custom validator: EmailAddressAttribute.</p> <pre><code>public class EmailAddressAttribute : RegularExpressionAttribute, IClientValidatable { public EmailAddressAttribute() : base("^[a-z0-9_\\+-]+(\\.[a-z0-9_\\+-]+)*@[a-z0-9]+(\\.[a-z0-9]+)*\\.([a-z]{2,4})$") { } protected override ValidationResult IsValid(object value, ValidationContext validationContext) { if (value != null) { if (!base.IsValid(value)) { return new ValidationResult( FormatErrorMessage(validationContext.DisplayName)); } } return ValidationResult.Success; } public IEnumerable&lt;ModelClientValidationRule&gt; GetClientValidationRules(ModelMetadata metadata, ControllerContext context) { var rule = new ModelClientValidationRule { ErrorMessage = FormatErrorMessage(metadata.GetDisplayName()) }; rule.ValidationParameters.Add("pattern", Pattern); rule.ValidationType = "emailaddress"; yield return rule; } } </code></pre> <p>And the accompanying script:</p> <pre><code>if ($.validator &amp;&amp; $.validator.unobtrusive) { $.validator.unobtrusive.adapters.addSingleVal("emailaddress", "pattern"); $.validator.addMethod("emailaddress", function (value, element, pattern) { return value.match(pattern); }); } </code></pre> <p>Thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
