Try this:

Set Enabled = .F. on every column that you don't what the user to enter (Now there should only be one enabled column left). then put the following code in the textbox control the user can edit.

KeyPress Event:
LPARAMETERS nKeyCode, nShiftAltCtrl

if nKeyCode = 13 or nKeyCode = 9
This.Valid(nKeyCode)
endif

Valid Event:
LPARAMETERS nKeyCode

if nKeyCode = 13 or nKeyCode = 9
if recno('YourGridTable') < reccount('YourGridTable')
KEYBOARD '{DNARROW}'
endif
endif

This code should be enough, it works for me...

>Yes, this was it. Now, something more difficult (I guess so): When I entered something in a field (in the grid) the focus goes automatically to the next column, even if Tab is .F. for this column. but I want to jump down to the next record, because the user is only allowed to enter one field (column) in the grid.
