So what exactly are you trying to do? You want to fire an storyboard animation when a button is 'held down' ('IsPressed') or when a button is clicked (tapped).

When you 'tap' a button you are in essence doing a mouse click. In touch IsPressed is only triggered when your contact is held down over the element and the movement threshold is passed to create a 'press' (That is why you see it if you press the finger down and slide it slightly)Īs soon as the contact comes up IsPressed = false. Is there a workaround for to make a 'tap' fire a press/click event? It does eventually work if enough pressure is applied with a finger and/or you roll or press like you would do for a fingerprint. It is only the XAML define style for the 'IsPressed' event that does not function as intended on a finger tap. The Windows 7 animation for the touch usually displays, and the button click event fires fine. My problem is that with Windows 7 multi-touch, the application does not recognize a finger 'tap' as a button press event, and therefore the button press Trigger to change color is never fired. I am developing a WPF kiosk like client that will be deployed on an HP TouchSmart Windows 7 machine with multi-touch enabled.
