RuleUniqueValueProperties	Represent the RuleUniqueValue Validation Rules‘ properties exported to the Application Model.
RuleValidatedEventArgs	Arguments passed to the RuleSet.RuleValidated event.
RuleValidationResult	Represents the results of checking an object via a Validation Rule.
RuleValueComparisonAttribute	Defines a validation rule that demands the target property’s value satisfy a specified condition.
RuleValueComparisonProperties	Represent the RuleValueComparison Validation Rules‘ properties exported to the Application Model.
ValidationCompletedEventArgs	Arguments passed to the RuleSet.ValidationCompleted event.
ValidationException	Occurs if the validation of an IRuleSet is unsuccessful.
Validator static	Provides access to the Validation Rules declared in an XAF application.

Interfaces

Name	Description
IEmptyCheckable	Declares the IEmptyCheckable.IsEmpty property to be implemented by classes to support validation via the RuleRequiredFieldAttribute.
IModelValidationDefaultErrorMessageTemplates	The ErrorMessageTemplates node defines the default templates for the messages displayed when validation rules are broken.
IRule	Declares members implemented by Validation Rules.
IRuleBaseProperties	Declares members implemented by classes which represent Validation Rules‘ properties exported to the Application Model.
IRuleCollectionPropertyProperties	Declares members implemented by classes which represent properties of Validation Rules that support collection validation, exported to the Application Model.
IRuleSet	Specifies a set of Validation Rules that can be checked against an object.
IRuleSource	Declares members that custom Validation Rule Sources implement.
