RuleRequiredFieldProperties Class

Represent the RuleRequiredField Validation Rules‘ properties exported to the Application Model.

Namespace: DevExpress.Persistent.Validation

Assembly: DevExpress.Persistent.Base.v21.2.dll

Declaration

C#
VB.NET

[DomainComponent]
public class RuleRequiredFieldProperties :
    RulePropertyValueProperties,
    IRuleRequiredFieldProperties,
    IRulePropertyValueProperties,
    IRuleCollectionPropertyProperties,
    IRuleBaseProperties

<DomainComponent>
Public Class RuleRequiredFieldProperties
    Inherits RulePropertyValueProperties
    Implements IRuleRequiredFieldProperties,
               IRulePropertyValueProperties,
               IRuleCollectionPropertyProperties,
               IRuleBaseProperties

Remarks

Information on the Validation Rules declared in the application is saved to the Application Model‘s IModelValidationRules node. Each rule has a corresponding node. These nodes expose properties specifying values for the rules’ properties.

The properties that must be exposed to the Application Model are specified via a rule’s RuleBase.Properties property. This property returns a RuleBaseProperties descendant.

When implementing a custom Validation Rule, you may need to implement a cusom Properties class inherited from RuleBaseProperties. For details, refer to the Implement Custom Rules topic.

The following code snippets (auto-collected from DevExpress Examples) contain references to the RuleRequiredFieldProperties class.
