Answer 1

Point pt;
private void panel1_MouseDown(object sender, MouseEventArgs e)
{
pt = Cursor.Position;
}

private void panel1_MouseMove(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
int px = Cursor.Position.X - pt.X;
int py = Cursor.Position.Y - pt.Y;
panel1.Location = new Point(panel1.Location.X + px, panel1.Location.Y + py);

pt = Cursor.Position;
}
}
