In the MouseEventArgs passed to your event there is a property called Location
.
According to MSDN
A Point that contains the x- and y- mouse coordinates, in pixels, relative to the upper-left corner of the form.
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
label1.Text = string.Format("X: {0} , Y: {1}", e.Location.X, e.Location.Y);
}
Does it solve your problem?
