Remarks

The KeyboardNavigation class is responsible for implementing default keyboard focus navigation when one of the navigation keys is pressed. The navigation keys are: Tab, Shift+Tab, Ctrl+Tab, Ctrl+Shift+Tab, UpArrow, DownArrow, LeftArrow, and RightArrow keys.

An example of logical navigation is using the tab key to move focus.

An example of directional navigation is using the arrow keys to move focus.

Examples

The following example creates a Menu with a number of MenuItem objects. The TabNavigation attached property is set to Cycle on the Menu. This means that when focus is changed using the tab key within the Menu, focus will move from each element and when the last element is reached focus will return to the first element.

XAML
<Menu KeyboardNavigation.TabNavigation="Cycle">
  <MenuItem Header="Menu Item 1" />
  <MenuItem Header="Menu Item 2" />
  <MenuItem Header="Menu Item 3" />
  <MenuItem Header="Menu Item 4" />
</Menu>
C#
Menu navigationMenu = new Menu();
MenuItem item1 = new MenuItem();
MenuItem item2 = new MenuItem();
MenuItem item3 = new MenuItem();
MenuItem item4 = new MenuItem();

navigationMenu.Items.Add(item1);
navigationMenu.Items.Add(item2);
navigationMenu.Items.Add(item3);
navigationMenu.Items.Add(item4);

KeyboardNavigation.SetTabNavigation(navigationMenu, 
    KeyboardNavigationMode.Cycle);
