copied!<p>I found in constructor some interesting things:</p> <pre><code>public BindingList() { // ... this.Initialize(); } private void Initialize() { this.allowNew = this.ItemTypeHasDefaultConstructor; if (typeof(INotifyPropertyChanged).IsAssignableFrom(typeof(T))) // yes! all you're right { this.raiseItemChangedEvents = true; foreach (T local in base.Items) { this.HookPropertyChanged(local); } } } </code></pre> <p>Quick fix 4 this behavior:</p> <pre><code>public class BindingListFixed<T> : BindingList<T> { [NonSerialized] private readonly bool _fix; public BindingListFixed() { _fix = !typeof (INotifyPropertyChanged).IsAssignableFrom(typeof (T)); } protected override void InsertItem(int index, T item) { base.InsertItem(index, item); if (RaiseListChangedEvents && _fix) { var c = item as INotifyPropertyChanged; if (null!=c) c.PropertyChanged += FixPropertyChanged; } } protected override void RemoveItem(int index) { var item = base[index] as INotifyPropertyChanged; base.RemoveItem(index); if (RaiseListChangedEvents && _fix && null!=item) { item.PropertyChanged -= FixPropertyChanged; } } void FixPropertyChanged(object sender, PropertyChangedEventArgs e) { if (!RaiseListChangedEvents) return; if (_itemTypeProperties == null) { _itemTypeProperties = TypeDescriptor.GetProperties(typeof(T)); } var propDesc = _itemTypeProperties.Find(e.PropertyName, true); OnListChanged(new ListChangedEventArgs(ListChangedType.ItemChanged, IndexOf((T)sender), propDesc)); } [NonSerialized] private PropertyDescriptorCollection _itemTypeProperties; } </code></pre> <p>Thanks for replies!</p>
