Getting the Popup to Close When It Loses Focus

Posted on December 11, 2007 by Matthias Shapiro

On a recent project, I spent (I kid you not) over three hours trying to get a stinking popup to close when I clicked somewhere else in the application.

 Figuring it was a focus issue, I tried the following triggers:

  • IsFocused
  • IsKeyboardFocused
  • IsKeyboardFocusWithin
  • IsMouseCapture
  • IsMouseCaptureWithin

All to no avail.

Turns out that the only thing I had to do was set the StaysOpen property of the Popup thus:

<Popup StaysOpen=”False“>

Handy little property. I just wish that it was the default.

    works fine if your popup has no buttons, textboxes etc (popup closes as soon as you focus the button).

    Thank you very much. I just spent more than 3 hours on that, trying to handle all kinds of events in the world. Just found it. Thanks for sharing.
