Is there a way to programatically close a menuitem in WPF

Question

I have a menu in wpf that has an input box and a button on it. Once the user clicks the button I need to close the menu.

Is there a way to do this?

I find that using IsSubmenuOpen doesn't properly eliminate focus from the Menu containing the MenuItem (especially if the Menu is in a ToolBar - the top-level MenuItem remains Selected even though the menu is "Closed"). I find sending a MouseUp event to the MenuItem works better (in the button's, or nested control's, Click event handler):

        private void button_Click(object sender, RoutedEventArgs e) {
           Button b = sender as Button;

           if (b == null || !(b.Parent is MenuItem))
              return;

           MenuItem mi = b.Parent as MenuItem;

           mi.RaiseEvent(
              new MouseButtonEventArgs(
                 Mouse.PrimaryDevice, 0, MouseButton.Left
              ) 
              {RoutedEvent=Mouse.MouseUpEvent}
           );
        }
