Getting an instance to a XAML class

I am sure this is a duplicate, but I can't find the answer to this.

I have a WPF window called Popup (so I have Popup.Xaml, Popup.Xaml.cs). Is there a way to determine if there is an active (visible) window instance of this class? I need to check if the popup is currently visible and skip doing some actions in a different class (a class that has no UI control associated with it) if the Popup window is currently visible.

thanks,

When you create your Popup just create global variable public static bool isPopupVisible = true (for ex in App class). Then you must handled event closing Popup and changed isPopupVisible = false. And that's all. Only check this variable whenever you need.

if (Application.Current.Windows.OfType<YourWindowType>().Any(x => x.IsActive))
{
   //... etc
}
