ModelBOModelMemberNodesGenerator Class

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

Namespace: DevExpress.ExpressApp.Model.NodeGenerators

Assembly: DevExpress.ExpressApp.v18.2.dll

Declaration

public class ModelBOModelMemberNodesGenerator :
    ModelNodesGeneratorBase
Public Class ModelBOModelMemberNodesGenerator
    Inherits ModelNodesGeneratorBase

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of BOModel | OwnMembers nodes. It gets a public members list from the business class' metadata information. It initializes the IModelMember nodes' properties with values specified in code via Data Annotations in Data Model applied to business class members, e.g CustomAttribute, IndexAttribute, LookupEditorModeAttribute, ImagesForBoolValuesAttribute, CaptionsForBoolValuesAttribute, ImageEditorAttribute, DataSourcePropertyAttribute, etc.

To customize the content of the OwnMembers 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 IModelBOModelClassMembers
        // to access the OwnMembers 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.
