UI.Web - Enable incremental filtering in all ASPxComboBox-based editors

Currently, as a workaround, you can use the following code:
using System;
using System.Web.UI.WebControls;
using DevExpress.Web.ASPxEditors;
using DevExpress.ExpressApp.Model;
using DevExpress.ExpressApp.Editors;
using DevExpress.ExpressApp.Web.Editors.ASPx;
namespace MainDemo.Module.Web {
    [PropertyEditor(typeof(object), EditorAliases.LookupPropertyEditor)]
    public class MyASPxLookupPropertyEditor : ASPxLookupPropertyEditor {
        public MyASPxLookupPropertyEditor(Type objectType, IModelMemberViewItem model)
            : base(objectType, model) {
        }
        protected override void SetupControl(WebControl control) {
            base.SetupControl(control);
            ASPxComboBox combo = ((ASPxLookupDropDownEdit)control).DropDown;
            if (combo == null) {
                DevExpress.Persistent.Base.Tracing.Tracer.LogWarning("Cannot find ASPxComboBox to customize it!");
            } else {
                combo.ClientSideEvents.DropDown = "function(s, e) { s.SelectAll(); } ";
                combo.IncrementalFilteringMode = IncrementalFilteringMode.Contains;
            }
        }
    }
}

Starting with 12.1, all ASPxComboBox-based editors in XAF Web UI will have incremental filtering enabled by default (IncrementalFilteringMode.Contains).
This small feature will improve the overall user experience, as most popular tasks can now be accomplished more intuitively. See the attached video for more details.
Thanks,
