Hi Thierry,

I'm using wActiveColumn in the wAfterRowChange () method.
At the 1st line change, wActiveColumn = 0, which can cause an error.
An example below. Without the correction of wActiveColumn, it's failed.

.wAfterRowChange()
LPARAMETERS tuRow && see documentation in awGrd.wAfterRowChange()
IF (Type('m.thisForm.wlHTMLgen') == 'L' AND m.thisForm.wlHTMLgen)
   RETURN .T.
ENDIF
IF !DoDefault(@m.tuRow)
   RETURN
ENDIF
WITH THIS.Parent
   IF THIS.wActiveColumn = 0
      THIS.wActiveColumn = 1
   ENDIF
   .Valgrid.Texte.Value = EVALUATE (THIS.Columns(THIS.wActiveColumn).ControlSource)
   .Valgrid.Texte.SetFocus
   .Refresh
ENDWITH

.wActiveColumn must return 0 when grid does not have focus.

You can change the default value of .wActiveColumnat design time in your xxxGrd sub-class

OK, but my grid necessarily has the focus with wAfterRowChange () no ?

yes but events in ActiveWidget grid fire in a different order than VFP

You can change the default value of .wActiveColumnat design time in your xxxGrd sub-class

It's works fine !

Thanks
