Just like Cetin wrote you have to put the setall command in the AfterRowColChange Method of the grid
(this method fired once you change between rows or columns)

Hello Cetin

The row grid is initially disabled and I have tried this
Thisform.pageframe1.page1.ackgrid.setall('enabled',IIF(RECNO('vwconsigna')<0,.t.,.f.))

The command before is executed in the click method of command button. The result is that all rows are enabled.

What is wrong?
