IComplexListEditor Interface

Declares members implemented by a List Editor to support receiving information on the application and Collection Source of the List View that uses the List Editor.

Namespace: DevExpress.ExpressApp.Editors

Assembly: DevExpress.ExpressApp.v24.2.dll

NuGet Package: DevExpress.ExpressApp

Declaration

C#

public interface IComplexListEditor

VB.NET

Public Interface IComplexListEditor

Remarks

In certain scenarios, a List Editor may require access to the application or the Collection Source of the List View that uses the List Editor. To get this information, the List Editor can implement the IComplexListEditor interface. This interface exposes a single IComplexListEditor.Setup method that passes this information to the List Editor.

When implementing a custom List Editor, support this interface if the List Editor requires information on the application and Collection Source to function properly.

Here is an example of how to implement IComplexListEditor in a ListEditor descendant.

C#

using DevExpress.ExpressApp;
using DevExpress.ExpressApp.Editors;
// ...
public class CustomListEditor : ListEditor, IComplexListEditor {
    private CollectionSourceBase collectionSource;
    private XafApplication application;
    #region IComplexListEditor Members
    public void Setup(CollectionSourceBase collectionSource, 
XafApplication application) {
        this.collectionSource = collectionSource;
        this.application = application;
    }
    #endregion
    // Example:
    protected override object CreateControlsCore() {
        IList objectsCollection = collectionSource.List;
        // ...
    }
}

VB.NET

Imports DevExpress.ExpressApp
Imports DevExpress.ExpressApp.Editors
'...
Public Class CustomListEditor
    Inherits ListEditor
    Implements IComplexListEditor

    Private collectionSource As CollectionSourceBase
    Private application As XafApplication
    #Region "IComplexListEditor Members"
        Public Sub Setup(ByVal collectionSource As CollectionSourceBase, _
ByVal application As XafApplication) Implements IComplexListEditor.Setup
            Me.collectionSource = collectionSource
            Me.application = application
        End Sub
    #End Region
    ' Example:
    Protected Overrides Function CreateControlsCore() As Object
        Dim objectsCollection As IList = collectionSource.List
        ' ...
    End Function
End Class
