TbrwColumn event setting after create()

[Gejza Horvath]

Hi,
I want to set the OnDrawCell event handling on the fly for TbrColumn object. When I set it
in the IDE, the generated code looks like this:
WITH OBJECT TArrayBrwColumn():New( ::oDBBrowse1 )
:cHeader := "Column1"
:cFooter := "Spolu"
:nWidth := 129
:nFooterImage := 10
:OnDrawCell := "RowColoring"
:Create()
END
and works fine.
The displayed dataset in the oDbfBrowse2 is dynamically changed by user, so I don't know
at the design time, which columns will be displayed, but I want to set the OnDrawCell
event, therefore I try:
METHOD FormInitialize( oSender ) CLASS TForm2
AEVAL(::oDbfBrowse2:aCols,{|x| x:OnDrawCell := "RowColoring"})
RETURN Nil
Executing the FormInitialize() method I get this error:

It isn't possible set this event after the control is created?

Take a look at method TBrowse:ColAtIndex()

Check the method RowColoring is defined on your TFORM??? module.
If is definded maybe is not working due the use of a code-block on the
OnDrawCell asignment of the event. Try to do the same job without AEVAL() or
do the following:
AEVAL(::oDbfBrowse2:aCols,{|x| x:OnDrawCell := {|oCol|
oCol:oParent:RowColoring()})

Ignacio,
thanks, this code does the job:
FOR i := 1 TO LEN(::oDbfBrowse2:aCols)
::oDbfBrowse2:aCols:OnDrawCell := "RowColoring"
NEXT
