UIElement.IsKeyboardFocusWithin Property

Gets a value indicating whether keyboard focus is anywhere within the element or its visual tree child elements. This is a dependency property.

Namespace:  System.Windows
Assembly:  PresentationCore (in PresentationCore.dll)

abstract IsKeyboardFocusWithin : bool with get 
override IsKeyboardFocusWithin : bool with get

Property Value

Type: System.Boolean
true if keyboard focus is on the element or its child elements; otherwise, false.

Implements

IInputElement.IsKeyboardFocusWithin

Identifier field

IsKeyboardFocusWithinProperty

Metadata properties set to true

None

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 an element by calling Focus, or by making a MoveFocus request. Either of these method calls might change this property value.

IsKeyboardFocused and IsKeyboardFocusWithin are typically used within class event handlers for other input-related events, for instance to determine whether the element already has keyboard focus, or to make determinations when mouse events and keyboard events occur in conjunction.
