Yes, I believe you can set editable to false – that’s what
I did, at least. The checkbox is still there as a renderer, and if you react on
its change event you can set the underlying datagrid data field to “true”
or “false” respectively. This should be remembered by the
ArrayCollection. BTW, this was not meant as a second alternative suggestion...it
was meant in combination with switching of the editable property. Am I making
sense ?

Weirdness with Online Example
iko, thanks for your
response. I can't set the editable="false" property on the grid
columns because then they won't report back selections / deselections to the
data provider (an ArrayCollection). Also, your second suggestion of manually
setting the "selected" property is already being done in my custom
AS3 renderer
in the overriden clickHandler() function.

[flexcoders] DataGrid Weirdness with Online Example
All,
DataGrid's are cool, but yeash I've run into a lot of
problems with
them. I've put
together two *real simple* online
demonstrations that illustrate the
behavior I'm
seeing with a grid. I'd love for someone
more experienced to check out
these
two examples and offer any insight or
solution.
http://www.trajiklyhip.com/flex/gridexample/DataGridExample1.html
This is a simple grid that uses
a custom Checkbox item renderer written
in AS3.
Clicking the submit button will display
whether or not each Checkbox is
selected.
Make some changes to the boxes,
de-selecting a few or an entire column
and
then click the submit button to see the
selected value. The Alert box
usually
displays the right info the first time
through, but after you've gone
through a few
rounds of selecting and de-selecting some
of the boxes it will not show
you the
correct true/false value of each box.
http://www.trajiklyhip..com/flex/gridexample/DataGridExample2.html
This is another simple grid that
is the same as the previous one only
with more
rows of data to make the DataGrid scroll.
De-select the first "Group
Owner"
Checkbox (row 1 with the ID = 12) and
then click use the grid scroll
bar to scroll
up and down. As you scroll, other
Checkboxes are selected and
deselected at
random.
Incidentally, if you right-click the DataGridExample1 movie
you can
view the source
to see what I'm doing.
