如何通知属性网格收集属性更改

Question

I have a wpf application and im using winform host. In some cases the 'SelectedItem' property is complex type that have a property from type 'List'. How can i know from code if the collection changed? Or just know of the custom editor opened?

Answer 1

You can use a ObservableCollection<T> instead of a List to have the functionality of indicating changes to the contents of the list.

The ObservableCollection implements the interfaces INotifyCollectionChanged and INotifyPropertyChanged to archive this behaviour.

More information to ObservableCollection on MSDN:

Answer 2

If I understand well you have collection of elements, and each of them have some other collection. In that way you could also consider using BindingList as your base collection - it implements IRaiseItemChangedEvents - Indicates whether a class converts property change events to System.ComponentModel.IBindingList.ListChanged
