RuleObjectExistsAttribute Members

Defines a validation rule that demands a particular type object that satisfies a specified criterion, exist in the database.

Properties

Name Description
CriteriaEvaluationBehavior Specifies whether to look for objects that are currently retrieved from the database, in addition to the objects in the database itself.
CustomMessageTemplate Specifies informational text to be added to the exception message, when the current rule is broken. Inherited from RuleBaseAttribute.
FoundObjectMessageFormat Gets or sets the format for specifying information on found objects in the validation error message.
FoundObjectMessagesSeparator Specifies a separator for the object list written in the error message for the current rule.
IncludeCurrentObject Specifies whether to check the current business object by this rule.
InvertResult Specifies whether the current rule should be inverted, to be checked. Inherited from RuleBaseAttribute.
LooksFor Specifies the type of objects to be looked for.
MessageTemplateFoundObjects
MessageTemplateMustExist Specifies the text to be written in the Validation Error window when the current rule is broken.
Name Specifies a name of the rule created using the current attribute. Inherited from RuleBaseAttribute.
ResultType Specifies the application behavior when the rule is broken. Inherited from RuleBaseAttribute.
SkipNullOrEmptyValues Specifies whether the current rule is checked for the properties that are set to null (Nothing in VB), an empty string (for string type propeties) or a minimal date (for DateTime type properties). Inherited from RuleBaseAttribute.
TargetContextIDs Specifies a context for checking the current Rule. Inherited from RuleBaseAttribute.
TargetCriteria Specifies a criterion that must be satisfied by the validated object or property to check rules. Inherited from RuleBaseAttribute.
TypeId When implemented in a derived class, gets a unique identifier for this Attribute. Inherited from Attribute.
