The following example demonstrates how to hide the ObjectHeaderFormat part of the validation message:

C#

using System;
using DevExpress.ExpressApp;
using DevExpress.Persistent.Validation;
// ...
namespace MySolution.Module.Controllers {
    public class CustomizeValidationMessageController : WindowController {
        public CustomizeValidationMessageController() {
            TargetWindowType = WindowType.Main;
        }
        protected override void OnActivated() {
            base.OnActivated();
            Validator.GetService(Application.ServiceProvider).ValidationCompleted += new EventHandler<ValidationCompletedEventArgs>(RuleSet_ValidationCompleted);
        }
        void RuleSet_ValidationCompleted(object sender, ValidationCompletedEventArgs e) {
            if (e.Exception != null) {
                e.Exception.ObjectHeaderFormat = "";
            }
        }
        protected override void OnDeactivated() {
            base.OnDeactivated();
            Validator.GetService(Application.ServiceProvider).ValidationCompleted -= new EventHandler<ValidationCompletedEventArgs>(RuleSet_ValidationCompleted);
        }
    }
}
