NavigationItemNodeGenerator Class

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

Namespace : DevExpress.ExpressApp.SystemModule

Assembly : DevExpress.ExpressApp.v25.2.dll

NuGet Package : DevExpress.ExpressApp

Declaration

C#
VB.NET

csharp

public class NavigationItemNodeGenerator :
    ModelNodesGeneratorBase

Public Class NavigationItemNodeGenerator
    Inherits ModelNodesGeneratorBase

Remarks

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the NavigationItems node. Adds IModelNavigationItem nodes for business classes that have the IModelClassNavigation.IsNavigationItem property set to true in the corresponding BOModel | <Class> node.

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

csharp

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