FocusManager Class

Provides a set of static methods, attached properties, and events for determining and setting focus scopes and for setting the focused element within the scope.

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

public static class FocusManager
You cannot directly create an instance of this class in XAML.

In Windows Presentation Foundation (WPF) there are two concepts concerning focus: keyboard focus and logical focus.

Keyboard focus pertains to the element which is currently receiving keyboard input. There can be only one element with keyboard focus. This element with keyboard focus has IsKeyboardFocused set to true. Keyboard.FocusedElement returns the element with keyboard focus.

Logical focus pertains to the FocusManager.FocusedElement within a specific focus scope.

A focus scope is a container element that keeps track of the FocusManager.FocusedElement within its scope. By default, the Window class is a focus scope as are the Menu, ContextMenu, and ToolBar classes. An element which is a focus scope has IsFocusScope set to true.

There can be multiple elements with logical focus, but there can only be one element with logical focus within a single focus scope. An element with logical focus does not necessarily have keyboard focus, but an element with keyboard focus will have logical focus. It is possible to define a focus scope within a focus scope. In this case, both the parent focus scope and the child focus scope can have a FocusManager.FocusedElement.

The following scenario illustrates how keyboard focus and logical focus change in a Windows Presentation Foundation (WPF) application that has a Window with a TextBox and a Menu which has a MenuItem. When keyboard focus changes from the TextBox to the MenuItem, the TextBox losses keyboard focus but retains logical focus for the Window focus scope. The MenuItem obtains keyboard focus and obtains logical focus for the Menu focus scope. When keyboard focus returns to the root Window, the element in Window focus scope with logical focus will obtain keyboard focus, which in this case is the TextBox. The TextBox now has keyboard focus and logical focus. The MenuItem loses keyboard focus, but retains logical focus for the Menu focus scope. 

The default value of IsFocusScope on a Window, Menu, ToolBar, and ContextMenu is true.
