Find all opened Popups in WPF application

Question

WPF has the Popup class with which you can open a (small) window inside another window. This is used for example for Tooltips or ComboBoxes.

I need to find all of these popups which are currently opened inside a WPF window, so I can close them.

Answer 1

If someone still need:

  public static IEnumerable<Popup> GetOpenPopups()
  {
      return PresentationSource.CurrentSources.OfType<HwndSource>()
          .Select(h => h.RootVisual)
          .OfType<FrameworkElement>()
          .Select(f => f.Parent)
          .OfType<Popup>()
          .Where(p => p.IsOpen);
  }
