Open WPF Popup Control without focus

I want to know if there is a way to open a WPF Popup without move focus to it.

When I set the property IsOpen = true of the Pupup the Applciation window lost focus (the Deactivated event is fired) and the focis is moved to the Popup and I want to maintain the window with the focus.

I already tried the method FocusManager.GetFocusedElement to get the previous element with focus and then set the focus to it again but 开发者_C百科it doesn't work for me.

Any ideas?

Thanks in advance.

Can you try one thing...

1. Make your Window handle Keyboard.PreviewLostKeyboardFocus.

   <Window Keyboard.PreviewLostKeyboardFocus="KeyboardFocusChangedEventHandler" ... />
   

2. In your handler handle the event for when popup is open.

   private void KeyboardFocusChangedEventHandler(object sender, KeyboardFocusChangedEventArgs e)
   {
          e.Handled = this.popup.IsOpen;
   }
   

Let me know if this works....

Try setting the Focusable property to false.
