Control type name, please. DateTinePicker? I don't know such thing. If it Forms? Tag it. The type name should be full, with the namespace.

To achieve the custom look for the control, you have to override the WndProc method, which is the method that processes all the window messages for this control.

C#

protected override void WndProc(ref Message m)
  {
   IntPtr hDC = GetWindowDC(m.HWnd);
   Graphics gdc = Graphics.FromHdc(hDC);
   switch (m.Msg)
   {
    case WM_NC_PAINT:
     SendMessage(this.Handle, WM_ERASEBKGND, hDC, 0);
     SendPrintClientMsg();
     SendMessage(this.Handle, WM_PAINT, IntPtr.Zero, 0);
     OverrideControlBorder(gdc);

     m.Result = (IntPtr)1; // indicate msg has been processed
     break;
    case WM_PAINT: base.WndProc(ref m);
     OverrideControlBorder(gdc);
     OverrideDropDown(gdc);
     break;
      case  WM_NC_HITTEST:
     base.WndProc(ref m);
     if (DroppedDown)
      this.Invalidate(this.ClientRectangle, false);
     break;
    default:
     base.WndProc(ref m);
     break;
   }
   ReleaseDC(m.HWnd, hDC);
   gdc.Dispose();
  }
