Add try this code to your gridview in design page.

I used this code to move my vertical scroll bar from the right of my datagridview to the left hand side.

I called MoveVerticalScrollBar after I bind my datagridview and I pass it the datagridview.

[DllImport("user32.dll", EntryPoint = "SetWindowPos")]
public static extern IntPtr SetWindowPos(IntPtr hWnd, int hWndInsertAfter, int x, int Y, int cx, int cy, int wFlags);

public static void MoveVerticalScrollBar(DataGridView gvHistory)
{
   const short SWP_NOZORDER = 0X4;
   const int SWP_SHOWWINDOW = 0x0040;

   IntPtr handle = new IntPtr();
   foreach (ScrollBar scroll in gvHistory.Controls)
      if (scroll.GetType() == typeof(VScrollBar))
         handle = scroll.Handle;

   var form = Control.FromHandle(handle);
   SetWindowPos(handle, 0, 0, 0, form.Bounds.Width, form.Bounds.Height, SWP_NOZORDER | SWP_SHOWWINDOW);
}
