ModelBOModelMemberNodesGenerator Class

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

Namespace: DevExpress.ExpressApp.Model.NodeGenerators

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public class ModelBOModelMemberNodesGenerator :
    ModelNodesGeneratorBase

VB.NET

Public Class ModelBOModelMemberNodesGenerator
    Inherits ModelNodesGeneratorBase

Remarks

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:

C#

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

VB.NET

Public Class Updater
    Inherits ModelNodesGeneratorUpdater(Of ModelBOModelMemberNodesGenerator)
    Public Overrides Sub UpdateNode(ByVal node As ModelNode)
        ' Cast the 'node' parameter to IModelOwnMembers
        ' to access the OwnMembers node.
    End Sub
End Class

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