Remarks

Classes implementing ICollectionView should use the following pattern:

Raise the CurrentChanging event before any change of currency and check the return value before proceeding and raising CurrentChanged event:

void MoveCurrentToNext()
{
    CurrentChangingEventArgs args = new CurrentChangingEventArgs();
    OnCurrentChanging(args);
    if (!args.Cancel)
    {
        // ... update private data structures ...
        CurrentChanged();
    }
}
