Hi JH_Levasseur,

You can get the Position by the StylusEventArgs

 public Readxmlspantotextblock()
        {
            InitializeComponent();

            this.StylusDown += Readxmlspantotextblock_StylusDown;
            this.StylusMove += Readxmlspantotextblock_StylusMove;
        }

        private void Readxmlspantotextblock_StylusMove(object sender, StylusEventArgs e)
        {
            Point pos = e.GetPosition(this);
        }

        private void Readxmlspantotextblock_StylusDown(object sender, StylusDownEventArgs e)
        {
            Point pos = e.GetPosition(this);
        }

You could handle Stylusdown.

https://msdn.microsoft.com/en-us/library/system.windows.uielement.stylusdown(v=vs.110).aspx

I think you can then do getposition(canvas).
