Hi Cemal.

>>When i click a command button on the form its run perfect.
But when i click a command button on a toolbar the valid event does not work.
Is this another bug? <<

No, this is not a bug. The problem here is that toolbars do not get focus. So the valid of the activeControl on the form does not fire. What you have to do is add a method to your form class, call it WriteBuffer, and SetFocus to the form's ActiveControl. Setting focus to it will cause its Valid to fire.

Code something like this:

LOCAL loControl, lnActiveColumn, loColumn

IF TYPE( '_Screen.Activeform.ActiveControl.Name' ) = 'C'
  loControl = _Screen.Activeform.ActiveControl
  IF LOWER( loControl.BaseClass ) = 'grid'
    *** Grids are special cases
    *** You have to specifically set focus to the active column
    *** in the grid. You have to loop through the grid's columns
    *** collection because active column actually refers to the grid's
    *** column order
    lnActiveColumn = loControl.ActiveColumn
    FOR EACH loColumn IN loControl
      IF loColumn.Columnorder = lnActiveColumn
        loColumn.Text1.SetFocus()
        EXIT
      ENDIF
    ENDFOR
  ELSE
    loControl.SetFocus()
  ENDIF
ENDIF

I wrote this code off the top of my head. It is untested and I do not guarantee that it is bug free. You will have to test it, but it gives you the general idea of what you need to do.
