You can get the coordinates of a System.Windows.UIElement relative to any other UIElement. Probably the most common scenario is to get the coordinates of a child element so this is our example.

C#

GeneralTransform generalTransform = childElement.TransformToVisual( parentElement );
Point childToParentCoordinates = generalTransform.Transform( new Point( 0, 0 ) );

Note! If the child is in left of the parent element or above it, the coordinates will be negative.

That's it!

    Where in the world did you find this snippet? Is this actually documented by Microsoft somewhere? Thanks a million. This was a huge help.
