ListView listView = param as ListView;

foreach(ListViewItem item in listView.Items) {
DemosNavigationService.MainWindow.Dispatcher.BeginInvoke(new Action(() =>{
foreach(var window in this.ChildWindows) {
window.Close();
}
listView.SelectedItem = item;

}), System.Windows.Threading.DispatcherPriority.Normal);
}

}
