  • Tip: How to get the relative coordinates of an element?

    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!
