FrameworkElement.MoveFocus Method

Moves the keyboard focus away from this element and to another element in a provided traversal direction.

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

'Declaration
Public Overrides NotOverridable Function MoveFocus ( _
	request As TraversalRequest _
) As Boolean

Parameters

request
Type: System.Windows.Input.TraversalRequest
The direction that focus is to be moved, as a value of the enumeration.

Return Value

Type: System.Boolean
Returns true if focus is moved successfully; false if the target element in direction as specified does not exist or could not be keyboard focused.

This implementation overrides UIElement.MoveFocus and seals the method.

The following example implements a handler that handles several possible button inputs. Each button represents a possible FocusNavigationDirection. The handler tracks the element with current keyboard focus, and calls MoveFocus on that element, by specifying the appropriate FocusNavigationDirection as initialization for the TraversalRequest type parameter provided.


			' Creating a FocusNavigationDirection object and setting it to a
			' local field that contains the direction selected.
			Dim focusDirection As FocusNavigationDirection = _focusMoveValue

			' MoveFocus takes a TraveralReqest as its argument.
			Dim request As New TraversalRequest(focusDirection)

			' Gets the element with keyboard focus.
			Dim elementWithFocus As UIElement = TryCast(Keyboard.FocusedElement, UIElement)

			' Change keyboard focus.
			If elementWithFocus IsNot Nothing Then
				elementWithFocus.MoveFocus(request)
			End If
