Have callback function for button while it is pressed on wp7 Silverlight

Question

In Windows Phone 7 Silverlight is there a way to be able to have a button that while I have it selected it calls on a callback function. Either that, or have to functions one for when the button is selected and one for when the button is released. Any ideas as how to do this?

Note that I have already looked at the the toolkit, and the gestures they provide do not include this.

Thanks!

For future reference, and to save some future soul the frustration of why the heck MS didn't implement this in the first place as part of their SDK... I ended up solving this problem by using ManipulationStarted to record the start time, and ManipulationEnd to record the end time of the gesture, and a separate thread to keep track of the ticks in between.
