Are you including the table in the DE? I just built a view, added it to a form, set buffering to 5, dropped it on the form as a grid, added a button with

IF !TABLEUPDATE(2)
MESSAGEBOX("Problem!")
ENDIF

and ran the form. I changed a number of records, clicked the button and the update worked. I verified the changes in the original table and the changes were there.

So it's not necessary to add the table the view is based on to the DE.

HTH,
