I have an UserControl that contains a ToggleButton and a Popup attached to it. Something like this:

<ToggleButton x:Name="TogglePopupButton"
              IsChecked={Binding ShowPopup}/>
<Popup x:Name="MyPopup"
       IsOpen={Binding ElementName="TogglePopupButton", Path="IsChecked"}>
    <!--Some code in here -->
</Popup>

My application monitors a few things and then set the ShowPopup property when something goes wrong and the message is shown in the pop-up.

When the ShowPopup property is set by some event handler, can we open the Popup control without having it focused? I would like to keep the focus on the Main Window.

I tried some ideas, like getting the popup window handle and use Windows API to show the popup window not-active and activate the main window, handle focus changed event, changing Focusable, etc., but without success…

Should I change the Popup to something else?

Thanks
