IRuleSupportsCollectionAggregatesProperties Interface

Declares members implemented by classes which represent properties of Validation Rules that support collection validation using aggregate funcitons, exported to the Application Model.

Namespace: DevExpress.Persistent.Validation
Assembly: DevExpress.Persistent.Base.v18.1.dll
public interface IRuleSupportsCollectionAggregatesProperties : IRulePropertyValueProperties, IRuleCollectionPropertyProperties, IRuleBaseProperties

When implementing a custom Validation Rules Properties class, it is generally easier to inherit from the RuleRangeProperties or RuleValueComparisonProperties class, instead of implementing the IRuleSupportsCollectionAggregatesProperties interface. To see an example of implementing a custom Validation Rule Properties class, refer to the Implement Custom Rules topic.
