Devexpress XAF Pessimistic Locking Example

The implementation for persistent classes is fast and easy.

How to implement:

1. Add the PessimisticLocker.Module to your project.
2. Set OptimisticLocking(false) in your class
3. Add the IPessimisticLocking interface to your class
4. Implement the IPessimisticLocking.Id property
5. Run your application

Examples:

    [OptimisticLocking(false)]
    public class Contact : BaseObject, IPessimisticLocking
    {
        public string Id => Oid.ToString();
        
        public Contact(Session session)
            : base(session)
        {
        }

        private string name;
        public string Name
        {
            get { return name; }
            set { SetPropertyValue(nameof(Name), ref name, value); }
        }
    }
     
    [OptimisticLocking(false)]
    public class Company : XPObject, IPessimisticLocking
    {
        public string Id => Oid.ToString();
        
        public Company(Session session)
            : base(session)
        {
        }

        private string name;
        public string Name
        {
            get { return name; }
            set { SetPropertyValue(nameof(Name), ref name, value); }
        }
    }
