How to get XY coordinates of a control at runtime in WPF? [duplicate]

For that, there is the TransformToAncestor method:

Point relativePoint = myVisual.TransformToAncestor(rootVisual)
                          .Transform(new Point(0, 0));

Where myVisual is the element you want to get the position of, and rootVisual is Application.Current.MainWindow or whatever you want the position relative to.
