I believe What you're looking for is already part of the API in the ObservableCollection(T) class. Example:

ObservableCollection myList = new ObservableCollection();

myList.CollectionChanged += new System.Collections.Specialized.NotifyCollectionChangedEventHandler(
    delegate(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)                    
    {
        if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
        {
            MessageBox.Show("Added value");
        }
    }
);

myList.Add(1);
