WPF Mouse down event no Coordinates

Question

I am using WPF mouse down event on a control. I want to get the X,Y coordinates but I am getting an error:

private void button_MouseDown(object sender, MouseButtonEventArgs e)
{
      double x = e.X, double y = e.Y;
}

I could not access the coordinates. I wonder why. Can Someone help? If mouse down is unable to get the coordinates, is there other way I can get the coordinate of the cursor when click?

what error do you get? Please post more details and information — Jehof, Jul 02 '13 at 08:32

You need to use the GetPosition method to retrieve the point.

private void button_MouseDown(object sender, MouseButtonEventArgs e)
{
    Point p = e.GetPosition(this);
    double x = p.X;
    double y = p.Y;
}

Try like

C#
private void button_MouseDown(object sender, MouseButtonEventArgs e)
    {
        double x = e.GetPosition("Name of your element" as IInputElement).X;
    }
