Keyboard.ClearFocus();

Kills both, logical as well as the keyboard focus.

  • This was exactly what I was looking for this evening!
  • This does not always clear focus: I have a problem where an AutoCompleteTextBox inside a ListBox does not lose focus when I run Keyboard.ClearFocus() from code-behind after a click somewhere.
  • ClearFocus causes GotFocus to not fire for the recently focused control while it still fires for other controls. That's a big problem for my custom onscreen keyboard, for example. It does cause the caret to disappear, which is probably all that "keyboard focus" entails. Maybe I'm more interested in something like "mouse focus."
  • Thank you Grault, I got the same problem. The best I have come up with is to move focus to some other control with other.Focus().
  • @Grault This only clears the keyboard focus, not the logical focus (which is what fires to the GotFocus event). There is always something with logical focus in your program. Either use the LostKeyboardFocus event or shift focus to another element (which shifts logical focus along with it) before clearing keyboard focus.
  • This code is great, Keyboard.ClearFocus() has some unintended side effects
  • Why the condition !((IInputElement)parent).Focusable have "!" infront? Shouldn't this condition be true if parent is focusable?
  • Mert - not sure but just browsing through this post it looks like by continuing looping until that condition is true is the point. That way the first focusable item terminates the loop.
  • @Mert - if parent is not focusable then parent is set in the loop to the parent's parent. At the point that the parent is focusable, the loop stops and the parent is focused.
  • @patrick, which unintended side effects? Could you give relevant examples?
