TValue oItem = (TValue)Activator.CreateInstance(typeof(TValue),
BindingFlags.Instance | BindingFlags.NonPublic,
null,
new object[] { m_nCleTemporaire },
System.Globalization.CultureInfo.CurrentCulture);

EventInfo oPropertyChanged = oItem.GetType().GetEvent("PropertyChanged");
MethodInfo eventHandler = this.GetType().GetMethod("Item_PropertyChanged",
BindingFlags.Instance | BindingFlags.NonPublic);

/** Next code line fails **/
Delegate d = Delegate.CreateDelegate(oPropertyChanged.EventHandlerType,
eventHandler);

The system says that it cannot murge the delegate with the defined type.

Why ???

Are you sure that PropertyChanged event is of type EventHandlerType?
Most usually you get this error because of that
