IsKeyboardFocusWithin Property

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)

public bool IsKeyboardFocusWithin { get; }

Property Value

Type: System.Boolean

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

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.
