ModelValidationRulesNodeGenerator Class

A Nodes Generator that generates the content of the IModelValidationRules node.

Namespace: DevExpress.ExpressApp.Validation

Assembly: DevExpress.ExpressApp.Validation.v24.1.dll

Declaration

public class ModelValidationRulesNodeGenerator :
    ModelNodesGeneratorBase

Remarks

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the Validation | Rules node. Collects Validation Rules specified in code and adds corresponding IModelRuleBase nodes.

To customize the content of the Rules node, implement a Generator Updater for this Nodes Generator by inheriting the ModelNodesGeneratorUpdater<T> class in the following manner:

public class Updater : ModelNodesGeneratorUpdater<NavigationItemNodeGenerator> {
    public override void UpdateNode(ModelNode node) {
        // Cast the 'node' parameter to IModelValidationRules
        // to access the Rules node.
    }
}

The Generator Updater above should be registered within the overridden ModuleBase.AddGeneratorUpdaters method.

For a complete list of available Nodes Generators, refer to the Built-in Nodes Generators topic.
