Remarks
IsSelected/IsHighlighted mirror IsChecked's own shape (set/clear a ControlState flag, no other side effects here) - Selector itself is what keeps them in sync with SelectedIndex/its internal highlighted index, including across a pool-and-reuse cycle (see AttachContainer(ItemContainer, int)).
Properties
IsHighlighted
Gets or sets a value indicating whether this item is the Selector popup's current keyboard/gamepad-highlighted item. Setting this sets/clears Highlighted.
public bool IsHighlighted { get; set; }Property Value
IsSelected
Gets or sets a value indicating whether this item is the Selector's current SelectedItem. Setting this sets/clears Selected.
public bool IsSelected { get; set; }Property Value
Methods
OnTap()
Invoked by Canvas when this element (or a descendant) is the target of a completed tap (see Tap). The base implementation does nothing.
protected override void OnTap()Remarks
Called on the hit-tested element and every one of its ancestors (bubbling, with no "handled" flag in
v1) - so e.g. a Button reacts to a tap on its label TextBlock just as it would to a tap on
its own background.
Events
Tapped
Occurs when this item is tapped - raised from OnTap(). Used by WrapGrid/ ListBox for click-to-select, since their realized items live in the normal visual tree (unlike Selector's popup items, which use their own separate mechanism - see Selector's own remarks).
