C#

public class ViewController1 : ViewController<ListView> {
    ASPxGridListEditor gridListEditor;
    protected override void OnActivated() {
        base.OnActivated();
        gridListEditor = View.Editor as ASPxGridListEditor;
        if (gridListEditor != null) {
            gridListEditor.CreateCustomDataItemTemplate += gridListEditor_CreateCustomDataItemTemplate;
        }
    }
    void gridListEditor_CreateCustomDataItemTemplate(object sender, CreateCustomDataItemTemplateEventArgs e) {
        if (e.ModelColumn.PropertyEditorType.IsSubclassOf(typeof(ASPxObjectPropertyEditorBase))) {
            e.CreateDefaultDataItemTemplate = true;
        }
    }
    protected override void OnDeactivated() {
        base.OnDeactivated();
        if (gridListEditor != null) {
            gridListEditor.CreateCustomDataItemTemplate -= gridListEditor_CreateCustomDataItemTemplate;
            gridListEditor = null;
        }
    }
}

VB.NET

Public Class ViewController1
    Inherits ViewController(Of ListView)
    Private gridListEditor As ASPxGridListEditor
    Protected Overrides Sub OnActivated()
        MyBase.OnActivated()
        gridListEditor = TryCast(View.Editor, ASPxGridListEditor)
        If gridListEditor IsNot Nothing Then
            AddHandler gridListEditor.CreateCustomDataItemTemplate, AddressOf gridListEditor_CreateCustomDataItemTemplate
        End If
    End Sub
    Private Sub gridListEditor_CreateCustomDataItemTemplate(ByVal sender As Object, ByVal e As CreateCustomDataItemTemplateEventArgs)
        If e.ModelColumn.PropertyEditorType.IsSubclassOf(GetType(ASPxObjectPropertyEditorBase)) Then
            e.CreateDefaultDataItemTemplate = True
        End If
    End Sub
    Protected Overrides Sub OnDeactivated()
        MyBase.OnDeactivated()
        If gridListEditor IsNot Nothing Then
            RemoveHandler gridListEditor.CreateCustomDataItemTemplate, AddressOf gridListEditor_CreateCustomDataItemTemplate
            gridListEditor = Nothing
        End If
