Scope

Change Description

Calling ObservableCollection<T>.Move on a collection bound to a ListBox with items selected can lead to erratic behavior with future selection or unselection of ListBox items

• Quirked
• Build-time break

Recommended Action

Calling ObservableCollection<T>.Remove and ObservableCollection<T>.Insert instead of ObservableCollection<T>.Move will work around this issue. Alternatively, this issue has been fixed in the .NET Framework 4.6 and may be addressed by upgrading to that version of the .NET Framework.

Affected APIs

• M:System.Collections.ObjectModel.ObservableCollection`1.Move(System.Int32,System.Int32)
• M:System.Collections.ObjectModel.ObservableCollection`1.MoveItem(System.Int32,System.Int32)
