Dear friends developers.
The property ScrollBars.Vertical or ScrollBars.Horizontal in the DataGridView
control is not working properly.
The horizontal and vertical bar is always visible.
Attached the following changes to correct operation.

Hello Marcelo,
Would you mind sending this as a patch?
It would be even better if you post this to the
mono-devel-list@lists.ximian.com for the patch to be reviewed and discussed.
Miguel.
