Gets a value that indicates whether keyboard focus is anywhere within the element or child elements.
Changes to the value of this property typically raise the IsKeyboardFocusWithinChanged event, unless a derived class has overridden OnIsKeyboardFocusWithinChanged to suppress the event.
You do not set this property directly, but you can set the focus to the element by calling Focus, or by making a MoveFocus request. Either of these method calls might change this property value.
