Comunicating Between ViewModels

Hello.

I have a main ViewModel that loads two seperate child viewmodels. like so:

///
/// Used to load edit/list user ViewModels.
///
public MVVM.ViewModelBase ViewModel
{
get { return viewModel; }
set
{
viewModel = value;
RaisePropertyChanged("ViewModel");
}
}
MVVM.ViewModelBase viewModel;
public UsersViewModel()
{
this.ViewModel = new UsersListViewModel();
}
///
/// Adds a new user
///
void addUserExecute()
{
ViewModel = new UsersEditViewModel(-1);
}
bool canAddUserExecute()
{
return true;
}
public ICommand AddUser { get { return new MVVM.RelayCommand(addUserExecute, canAddUserExecute); } }

I can't seem to figure out how to let my child (UsersEditViewModel) to tell the parent that i'm done editing and need to close/dispose.

Any help would be greatly appreciated.

Manage a flag and change after parent value changes and on the bases of flag value manage the child value
