Attempts to move focus from this element to another element. The direction to move focus is specified by a guidance direction, which is interpreted within the organization of the visual parent for this element.
Assembly: PresentationCore (in PresentationCore.dll)
A traversal request, which contains a property that indicates either a mode to traverse in existing tab order, or a direction to move visually.
Return ValueType: System.Boolean
