just add this to your .cs code

protected override void WndProc(ref Message m)
{
    const int WM_NCLBUTTONDOWN = 161;
    const int WM_SYSCOMMAND = 274;
    const int HTCAPTION = 2;
    const int SC_MOVE = 61456;
    if ((m.Msg == WM_SYSCOMMAND) && (m.WParam.ToInt32() == SC_MOVE))
    {
         return;
    }
    if ((m.Msg == WM_NCLBUTTONDOWN) && (m.WParam.ToInt32() == HTCAPTION))
    {
         return;
    }
    base.WndProc(ref m);
}
