John -
The problem is likely related to the DataGridColumn.editorDataField
property. If you are using DateField etc. for an editor this property
is "data" and it assumes that you will be assigning a Date object or a
String that is in a format that the Date class can parse. (as shown in
code snippet below).
It seems you would have to extend DateField and override set
data(object:Value) or add a new property like dateMillis:Number then set
your column to have editorDataField="dateMillis", then write the
necessary code in your customized editor class.

--- From DateField.as ---
public function set data(value:Object):void
{
var newDate:Date;
_data = value;
if (_listData && _listData is DataGridListData)
newDate = _data[DataGridListData(_listData).dataField];
else if (_listData is ListData && ListData(_listData).labelField
in _data)
newDate = _data[ListData(_listData).labelField];
else if (_data is String)
newDate = new Date(Date.parse(data as String));
else
newDate = _data as Date;
if (newDate && !selectedDateSet)
{
selectedDate = newDate;
selectedDateSet = false;
}
dispatchEvent(new FlexEvent(FlexEvent.DATA_CHANGE));
}

Hi,
I've been pounding away at a problem dealing with DataGrids and
DateFields for a few days now. The problem is that I want to send and
receive Dates from the server using milliseconds. However, in the
data grid I want to display and edit Dates in MM/DD/YYYY format. One
solution is to convert milliseconds to Dates and from Dates to
milliseconds right as I send or receive data - and let the datagrid
deal just with Dates. That is what I finally did to get it to work.
What I would rather do is to not have to convert the data at the
service calls/results, but to let the datagrid renderer and editors
handle the conversion as necessary. However, I tried changing the
get/set data methods on the DateField (the editor) and the
Label/TextField (the renderer), but could never get something to work
that would both display the Date and edit it in the correct format. I
thought I was understanding which methods need to be modified, but I
realize I'm not. Could someone please help me understand which
methods need to be changed to allow for the data to be stored in
milliseconds in the Array Collection, but be displayed and edited in
the Date format?
Thank you very much for any help,
John
