OptimizedObservableCollection - markjulmar/xamu-infrastructure GitHub Wiki

This class provides a derived version of the ObservableCollection<T> which allows you to turn change notifications off for a period of time. This is useful if a lot of data is going to change in the collection at once to avoid a bunch of binding updates being done serially.

• BeginMassUpdate : turns off change notifications and returns an IDisposable object which must be disposed to turn them back on.

var collection = new OptimizedObservableCollection<string>() { ... };

using (collection.BeginMassUpdate())
{
   .. // Do a bunch of changes here.

} // UI is notified about all changes here.
