- selectionModeValueA named constant of the SelectionMode enumeration, such as Extended.

| Mode | Behavior |
|---|---|
| Single | A user can select a single item using the space bar, mouse click, or touch tap. A user can deselect an item using a downward swipe gesture. While pressing Ctrl: a user can deselect the item by using the space bar, mouse click, or touch tap. Using the arrow keys, a user can move focus independently of selection. |
| Multiple | A user can select multiple items using the space bar, mouse click, or touch tap to toggle selection on the focused item. Using the arrow keys, a user can move focus independently of selection. |
| Extended | With no modifier keys: the behavior is the same as Single selection. While pressing Ctrl: a user can select multiple items using the space bar, mouse click, or touch tap to toggle selection on the focused item. Using the arrow keys, a user can move focus independently of selection. While pressing Shift: a user can select multiple contiguous items by clicking or tapping the first item in the selection and then the last item in the selection. Using the arrow keys, a user can create a contiguous selection starting with the item selected when Shift is pressed. |
When SelectionMode is Single, use the Selector.SelectedItem property to get the item that's selected. When SelectionMode is Multiple or Extended, use the SelectedItems property to get the items that are selected.
