How to find absolute position of control

The following code from MSDN come in very handy today, just change “this” to your control and it’ll give your the absolute position of your control on the page:

GeneralTransform gt = this.TransformToVisual(Application.Current.RootVisual as UIElement);
Point offset = gt.Transform(new Point(0, 0));
double controlTop = offset.Y;
double controlLeft = offset.X;
