ModelListViewFiltersGenerator Class

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

Namespace: DevExpress.ExpressApp.SystemModule

Assembly: DevExpress.ExpressApp.v23.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public class ModelListViewFiltersGenerator :
    ModelNodesGeneratorBase

VB.NET

Public Class ModelListViewFiltersGenerator
    Inherits ModelNodesGeneratorBase

Remarks

This class is a ModelNodesGeneratorBase descendant, that generates child nodes of the View | ListView | Filters node. Collects filters specified for the current List View’s business class via the ListViewFilterAttribute attributes. Creates the IModelListViewFilterItem for each filter.

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

C#

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

VB.NET

Public Class Updater
    Inherits ModelNodesGeneratorUpdater(Of )
    Public Overrides Sub UpdateNode(ByVal node As ModelNode)
        ' Cast the 'node' parameter to IModelListViewFilters
        ' to access the Filters 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 Filters Application Model Node topic.
