WPF Listview : Column reorder event?

I need to sync the column order of two ListViews event when the user changes the order. But it seems there is not a Column reorder event.

For the moment I just did a AllowsColumnReorder="False" but that is not a permanent solution. While searching the net I found many people with the same problem but no solution. What can be done?

I'm not sure it works, but you could probably take advantage of the fact that GridView.Columns is an ObservableCollection : you could subscribe to the CollectionChanged event and handle the case where Action = Move

GridView gridView = (GridView)listView.View;
gridView.Columns.CollectionChanged += gridView_CollectionChanged;

private void gridView_CollectionChanged(object sender, CollectionChangedEventArgs e)
{
    if (e.Action == NotifyCollectionChangedAction.Move)
    {
        string msg = string.Format("Column moved from position {0} to position {1}", e.OldIndex, e.NewIndex);
        MessageBox.Show(msg);
    }
}
