To do this you need to change Panel's Location property like this:
panel1.Location = new Point(X,Y);
If you don't know exact coordinates,then you can handle Form MouseMove event (temporarily)
private void Form1_MouseMove(object sender, MouseEventArgs e)
{
label1.Text = e.X + "," + e.Y;
}
Move mouse to the location where you want to panel move and note coordinates, then handle button click event and change panel's location
private void CP_OneFbutton_Click(object sender, EventArgs e)
{
panel1.Location = new Point(X,Y); // type your X and Y coordinates here
panel1.Visible = true; // Display the panel
}
