This works fine for me. Here is my code, when I run it and press tab the wait window appears.

CREATE CURSOR cJunk (field_one c(20), f2 c(20))
FOR lni = 1 TO 10
INSERT INTO cJunk VALUES (REPLICATE('W',lni), REPLICATE('ab',lni))
endfor
GO TOP
LOCAL aobj[1], xx
DELETE FILE testxx.sc?
CREATE FORM testxx NOWAIT
=ASELOBJ(aobj,1)
xx = aobj[1]
xx.autocenter = .t.
xx.addobject('text1','textbox')
xx.addobject('grid1','grid')
xx.grid1.columncount = 2
xx.grid1.top = 35
xx.grid1.allowcellselection = .f.
xx.grid1.writemethod('when','wait window Program() time 1')
ACTIVATE WINDOW 'form designer - testxx.scx'
KEYBOARD '{ctrl+w}'
DO FORM testxx
return

If you are expecting the When event to fire for controls in columns, this will not happen, as AllowCellSelection prevents individual grid controls from gaining focus.

I hope this helps!

>I am using the VFP8 native grid for my classes. I just discovered that when you set the grid property AllowCellSelection to false the grid doesn't pass pass throught the method WHEN and i have some code in the when method.
