ModelDetailViewItemsNodesGenerator Class

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

Namespace: DevExpress.ExpressApp.Model.NodeGenerators

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public sealed class ModelDetailViewItemsNodesGenerator :
    ModelNodesGeneratorBase

VB.NET

Public NotInheritable Class ModelDetailViewItemsNodesGenerator
    Inherits ModelNodesGeneratorBase

Remarks

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the Views | View | Items node. If the parent View node is IModelObjectView, it adds IModelPropertyEditor nodes for members of the current object that should be visible. Separate PropertyEditor nodes are generated for aggregated objects’ members, if this option is enabled via the ExpandObjectMembersAttribute attribute.

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

C#

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

VB.NET

Public Class Updater
    Inherits ModelNodesGeneratorUpdater(Of ModelDetailViewItemsNodesGenerator)
    Public Overrides Sub UpdateNode(ByVal node As ModelNode)
        ' Cast the 'node' parameter to IModelItems
        ' to access the Items node.
    End Sub
End Class

The Generator Updater above should be registered within the overridden ModuleBase.AddGeneratorUpdaters method. The complete example of implementing a Generator Updater for this Nodes Generator is provided in the How to: Implement a View Item topic.
