Gotta use editField or dispatch an event. The examples in the Flex docs on
cellrenderers is a good one to look at. If you want to allow the CheckBox
to screw with the data in his cellRenderer, do this in his click function:
listOwner.editField(getCellIndex().itemIndex, getDataLabel(),
check.selected);
That's, "In the dataProvider, at position 0, set the field 'selected' to a
value of 'true'".
or:
myDataProvider[0].selected = true;
Otherwise, dispatch an event so the controller that hosts the view can mess
with the data himself:
listOwner.dispatchEvent({type: "checkBoxClicked", target: listOwner, cell:
this, selected: checkBox.selected});

Subject: [flexcoders] Recognizing when a CheckBox inside a DataGrid is
clicked
[env: Flex 1.5 with Cairngorm architecture]
I am using the CheckBoxCellRenderer provided by Peter Ent via this
download:
http://www.markme.com/pent/archives/flex/solutions/cellrenderers.zip
I have my program working such that when a user clicks the Save button
in my mxml file, all the rows whose CheckBoxes are checked are stored
in a new Array by a save() function in the mxml's ViewHelper.
What I would like to do now is update the text in one of the cells
when the CheckBox is clicked. To be more specific, each row in the
DataGrid has a "date" column, and when the row's CheckBox is clicked,
I'd like the current date to replace the date displayed in that row's
"date" column.
However, I can't figure out how to get the CheckBox to realize it has
been clicked so that I can call the updateDate() function in the
mxml's ViewHelper. I tried modifying the code in the
CheckBoxCellRenderer class, but from there, I couldn't find an easy
way to access the mxml's DataGrid and its dataProvider. I tried using
the "change" property of the DataGrid, but that only recognizes that a
row has been selected, not that a CheckBox has been clicked.
[As an aside, I noticed while I was modifying the CheckBoxCellRenderer
that the setValue() function is called twice everytime the mouse
passes over a DataGrid row containing a checked CheckBox(es). This
seemed odd.]
Thanks in advance!
