How to show a full member path in the LayoutControl's Customization Form to avoid similar captions for properties with the same last member

It is possible to use the BaseLayoutItem.CustomizationFormText property to accomplish this task. Here is an example of how to show a dot-separated member caption including all sub-properties:

C#
using DevExpress.ExpressApp.Editors;  
using DevExpress.ExpressApp.Utils;  
using DevExpress.ExpressApp.Win.Layout;  

public class CustomizationFormCaptionController : ViewController<DetailView> {  
    protected override void OnActivated() {  
        base.OnActivated();  
        ((WinLayoutManager)View.LayoutManager).ItemCreated += CustomizationFormCaptionController_ItemCreated;  
    }  
    void CustomizationFormCaptionController_ItemCreated(object sender, ItemCreatedEventArgs e) {  
        if (e.ViewItem is PropertyEditor) {  
            e.Item.CustomizationFormText = CaptionHelper.GetFullMemberCaption(View.ObjectTypeInfo, (((PropertyEditor)e.ViewItem).MemberInfo).Name);  
        }  
    }  
    protected override void OnDeactivated() {  
        base.OnDeactivated();  
        ((WinLayoutManager)View.LayoutManager).ItemCreated -= CustomizationFormCaptionController_ItemCreated;  
    }  
}
