ModelValidationContextsNodeGenerator Class

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

Namespace: DevExpress.ExpressApp.Validation

Assembly: DevExpress.ExpressApp.Validation.v18.2.dll

Declaration

public class ModelValidationContextsNodeGenerator :
    ModelNodesGeneratorBase
Public Class ModelValidationContextsNodeGenerator
    Inherits ModelNodesGeneratorBase

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the Validation | Contexts node. It uses IRuleBaseProperties.TargetContextIDs values from the Validation | Rules | Rule nodes to collect Validation Contexts, and adds an IModelValidationContext node for each Context.

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

public class Updater : 
    ModelNodesGeneratorUpdater<> {
    public override void UpdateNode(ModelNode node) {
        // Cast the 'node' parameter to IModelValidationContexts
        // to access the Contexts 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.
