BindingList.Sort() to behave like a List.Sort()

Emulating a property just to do the sort is probably overkill.
The first thing to look at is Comparer<T>.Default. It might, however, turn out that the easiest thing to do is to:

• extract the data into List<T> or similar
• sort the extracted data
• disable notifications
• reload the data
• re-enable notifications
• send a “reset” message

btw, you should be disabling notifications during your existing sort, too.

public void Sort() {
    // TODO: clear your "sort" variables (prop/order)

    T[] arr = new T[Count];
    CopyTo(arr, 0);
    Array.Sort(arr);
    bool oldRaise = RaiseListChangedEvents;
    RaiseListChangedEvents = false; // <=== oops, added!
    try {
        ClearItems();
        foreach (T item in arr) {
            Add(item);
        }
    } finally {
        RaiseListChangedEvents = oldRaise;
        ResetBindings();
    }    
}
