WPF Mouse down event no Coordinates

mousedown, wpf

Solution

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;
}

Problem

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?
