There is both a property and an event. The property is EnterKeyBehavior. Here is a setting that turns off any action by the enter key.
this.gridControl1.EnterKeyBehavior = GridDirectionType.None;
The event is QueryNextCurrentCellPosition. Here is code that will move you to 1,1 anytime you try to tab into cell 3,3.
private void grid_QueryNextCurrentCellPosition(object sender, GridQueryNextCurrentCellPositionEventArgs e)
if(e.ColIndex == 3 && e.RowIndex == 3)
e.ColIndex = 1;
e.RowIndex = 1;
e.Handled = true;
e.Result = true;
