Properties

ErrorMessage	Gets or sets an error message to associate with a validation control if validation fails. (Inherited from ValidationAttribute)
ErrorMessageResourceName	Gets or sets the error message resource name to use in order to look up the ErrorMessageResourceType property value if validation fails. (Inherited from ValidationAttribute)
ErrorMessageResourceType	Gets or sets the resource type to use for error-message lookup if validation fails. (Inherited from ValidationAttribute)
ErrorMessageString	Gets the localized validation error message. (Inherited from ValidationAttribute)
Length	Gets the maximum allowable length of the array or string data.
RequiresValidationContext	Gets a value that indicates whether the attribute requires validation context. (Inherited from ValidationAttribute)
