 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.
