Methods
OnActivate()
Invoked by Canvas for an activation press (Enter, gamepad A) while this element or one of its descendants has focus.
protected override bool OnActivate()Returns
- bool
true to claim the press; Canvas then stops calling further ancestors. The base implementation returns false.
Remarks
Clicks the button, like a tap, unless it's disabled.
OnClick()
protected virtual void OnClick()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
Click
Occurs when the button is tapped/activated.
