PopUp window is still visible on screen if the MainWindow is out of focus in WPF

I have a PopUp window with a popup control.There is a main window from which this PopUp is displayed. PopUp displays data after processing the query which takes time.So while the data in the PopUp is processing,if I maximise other windows then the PopUp is displayed on the other windows as well.

I have made MainWindow owner of the PopUp window in PopUpWindow.xaml.cs as:

this.Owner = Application.Current.MainWindow;

and I have set "StaysOpen" property of PopUp Window to false.But still issue persists.How to stop PopUp from displaying on other window,if other windows are maximised.

You can explicitly close the popup when its owner window is deactivated, i.e. when another window gets the focus and comes to the top, using the Deactivated event:

    window.Deactivated += 
        (sender, args) => {
            thePopup.IsOpen = false;
        };

You might also want to capture the IsOpen state and restore it when the window is Activated.
