Assembly: PresentationCore (in PresentationCore.dll)
Logical focus might differ from keyboard focus if an application has multiple focus divisions, such as between menu contents and the remainder of the application. In this scenario, keyboard focus can only be on one element of the application UI, however, certain elements in other focus divisions might still retain logical focus. For more information on logical focus, see Focus Overview.
You do not set focus by setting this property (it is read-only). The typical use for this property is to use it as a dependency property for a Setter or EventTrigger. To set focus programmatically, call Focus. Focus can also be set by user action or by control implementations, which possibly include mouse capture behavior.
