ConditionalAppearance - Provide events allowing you to provide custom appearance customizations

We have introduced the CustomApplyAppearance and AppearanceApplied events into the DevExpress.ExpressApp.ConditionalAppearance.AppearanceController class.
Both use the DevExpress.ExpressApp.ConditionalAppearance.ApplyAppearanceEventArgs class as event arguments:

	
[C#]
public class ApplyAppearanceEventArgs : HandledEventArgs {
        public ApplyAppearanceEventArgs(IAppearance appearance, AppearanceItemType itemType, string itemName, object item, object[] contextObjects);
        public IAppearance Appearance { get; }
        public object[] ContextObjects { get; }
        public object Item { get; }
        public string ItemName { get; }
        public AppearanceItemType ItemType { get; }
    }

Let's demonstrate the use of the CustomApplyAppearance event with a small sample:

	
[C#]
public class S30263 : ViewController<ListView> {
        protected override void OnActivated() {
            base.OnActivated();
            Frame.GetController<AppearanceController>().CustomApplyAppearance += new EventHandler<ApplyAppearanceEventArgs>(S30263_AppearanceApplied);
        }
        protected override void OnDeactivated() {
            Frame.GetController<AppearanceController>().CustomApplyAppearance -= new EventHandler<ApplyAppearanceEventArgs>(S30263_AppearanceApplied);
            base.OnDeactivated();
        }
        private void S30263_AppearanceApplied(object sender, ApplyAppearanceEventArgs e) {
            if (e.ItemType == AppearanceItemType.ViewItem.ToString() && e.ItemName == "TargetFormattingProperty" && e.ContextObjects.Length>0) {
                //Dennis: Use the code below to cancel appearance customizations for the selected records in the ListView.
                e.Handled = View.SelectedObjects.Contains(e.ContextObjects[0]);
                //Or
                //Dennis: Cast the e.Item property to the IViewElementProvider interface and then use its ViewElement property to access underlying object for additional customizations.
                //DevExpress.ExpressApp.Editors.IViewElementProvider provider = (DevExpress.ExpressApp.Editors.IViewElementProvider)e.Item;
                //DoSomethingInCaseOfXtraGrid(provider.ViewElement as DevExpress.XtraGrid.Views.Grid.RowCellStyleEventArgs);                
            }
        }
    }
