Find popup window in Wpf

Hi, I want to get all opened popups in a specific window in Wpf, but I couldn't find a solution to solve it.

I found that in Uwp exists VisualTreeHelper.GetOpenPopups(), but is there any option to use it in Wpf?

You could use reflection to access the Window._showingAsDialog field, then iterate it using Application.Current.Windows.Cast<Window>().Where(x => x.Parent == targetParenttWindow && IsOpenedAsDialog(x))

It's not working for popups used for example in combobox I found solution

PresentationSource.CurrentSources.OfType<HwndSource>() 
                .Select(h => h.RootVisual) 
                .OfType<FrameworkElement>() 
                .Select(f => f.Parent) 
                .OfType<Popup>() 
                .Where(popup => popup.IsOpen);

PresentationSource.CurrentSources.OfType<HwndSource>() 
                .Select(h => h.RootVisual) 
                .OfType<FrameworkElement>() 
                .Select(f => f.Parent) 
                .OfType<Popup>() 
                .Where(popup => popup.IsOpen);
