AppearanceRulesModelNodesGenerator Class

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

Namespace: DevExpress.ExpressApp.ConditionalAppearance

Assembly: DevExpress.ExpressApp.ConditionalAppearance.v20.2.dll


public class AppearanceRulesModelNodesGenerator :
Public Class AppearanceRulesModelNodesGenerator
    Inherits ModelNodesGeneratorBase


This class is a ModelNodesGeneratorBase descendant, that generates child nodes of a BOModel | <Class> | AppearanceRules node. It collects AppearanceAttribute attributes applied in a business class code, and adds corresponding IModelAppearanceRule nodes.

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

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