ModelListViewColumnsNodesGenerator Class

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

Namespace: DevExpress.ExpressApp.Model.NodeGenerators

Assembly: DevExpress.ExpressApp.v20.2.dll


public class ModelListViewColumnsNodesGenerator :
    ModelListViewColumnsNodesGeneratorBase<IModelColumn, IModelColumn>
Public Class ModelListViewColumnsNodesGenerator
    Inherits ModelListViewColumnsNodesGeneratorBase(Of IModelColumn, IModelColumn)


This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the Views | <ListView> | Columns node. It adds IModelColumn nodes that represent columns of the current List View. The rules for generating the default column set are described in the List View Column Generation topic.

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

public class Updater : ModelNodesGeneratorUpdater<ModelListViewColumnsNodesGenerator> {
    public override void UpdateNode(ModelNode node) {
        // Cast the 'node' parameter to IModelColumns
        // to access the Columns 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.
