Find position of Button/UIElement on screen relati

问题:

I can't find a way to get the position in (x,y) co-ordinates of an on-screen control like a button relative to the grid that it is inside. Is there a way to do this that I am overlooking?

回答1:

var transform = button.TransformToVisual(grid);        
Point absolutePosition = transform.Transform(new Point(0, 0));
