While keyboard navigating a WPF app, in one step, between one control and another, the Keyboard.FocusedElement is null. If there is no reference to this property in the code, which methods can cause this? Is there an Unfocus method for any control?
One way this could happen is if focus is on a control and then the
Focusableproperty of that control is set to false.Keyboard.FocusedElementwould then be null.
