    Look at the sample in the MSDN:

    //Add the Path Element
myPath = new Path();
myPath.Stroke = System.Windows.Media.Brushes.Black;
myPath.Fill = System.Windows.Media.Brushes.MediumSlateBlue;
myPath.StrokeThickness = 4;
myPath.HorizontalAlignment = HorizontalAlignment.Left;
myPath.VerticalAlignment = VerticalAlignment.Center;
EllipseGeometry myEllipseGeometry = new EllipseGeometry();
myEllipseGeometry.Center = new System.Windows.Point(50,50);
myEllipseGeometry.RadiusX = 25;
myEllipseGeometry.RadiusY = 25;
myPath.Data = myEllipseGeometry;
myGrid.Children.Add(myPath);

    It is the line myPath.Data = myEllipseGeometry; that you are looking for. Just assign it a Geometry object.
