Remarks

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.
