Well, the value property is a little strange indeed. Not to mention
it's also deprecated. Here's what I suggest:
/* in your item editor */
public function get myCustomProperty():Object
{
var item:Object = selectedItem;
if (item == null)
return null;
return item.data;
}
DataGridColumn editorDataField=myCustomProperty ... /

Re: [flexcoders] itemRenderer ComboBox
Yes that's what it takes, thanks!
I used an itemRenderer to set the display to the label from the lookup
source for the data that was stored.

Re: [flexcoders] itemRenderer ComboBox
Ok, so the itemEditor = ComboBox with the above Override and here it is as it
stands and works (up to a point).
mx:DataGridColumn headerText=Reason Stopped
dataField=reason_med_stopped_oidCol
editorDataField=selectedItem
mx:itemEditor
mx:Component
mx:ComboBox editable=true labelField=label
mx:ArrayCollection
mx:Object label=Patient Died
data=130/
mx:Object label=Maximum dosage
data=131/
mx:Object label=Consulting Decision
data=132/
/mx:ArrayCollection
mx:Script
![CDATA[
import
mx.collections.IViewCursor;
override public function set
data(value:Object):void
{
super.data = value;
var
listCursor:IViewCursor = collection.createCursor();
do
{
if
(data.reason_med_stopped_oidCol ==
listCursor.current.data)
{
selectedItem =
listCursor.current;
break;
}
}
while
(listCursor.moveNext());
}
]]
/mx:Script
/mx:ComboBox
/mx:Component
/mx:itemEditor
/mx:DataGridColumn
Now this works perfectly now when I click in the Cell the ComboBox opens
with the selectedItem and when I select an option and exit the Cell the
DataGridEvent.ITEM_EDIT_END fires and I extract the data value to insert
into the parameters with
parameters[dsFieldName.substr(0,dsFieldName.length-3)] =
e.currentTarget.itemEditorInstance.selectedItem.data;
and that saves to the database, all great...however, the
editorDataField=selectedItem puts [object Object] into the Grid instead
of the data element.
I tried editorDataField=selectedItem.data but that fails. I tried value
and text but it saves the Label.
So what do I put in the editorDataField to save the 'data' to the Grid
instead of the object string or the label?

Strange. Setting editorDataField to 'value' should work if you have a
field called 'data' in the selected item and that's the value you're
looking for.

Re: [flexcoders] itemRenderer ComboBox
it looks to me like it is better to use a label function to render the display value and leave the combo box for itemEditor. That still leaves the question on how the ComboBox will display the Option Label when in edit mode. -- View this message in context: http://www.nabble.com/itemRenderer-ComboBox-tp21243094p21245495.html Sent from the FlexCoders mailing list archive at Nabble.com.

The ComboBox won't select the item based on the value of the 'text'
property, so you'll have to do the selection for it, by overriding the
data setter.
override public function set data(value:Object):void
{
super.data = value;
var listCursor:IViewCursor = collection.createCursor();
do
{
if (data.med_route_oidCol == listCursor.current.text)
{
selectedItem = listCursor.current;
break;
}
}
while (listCursor.moveNext());
}

Re: [flexcoders] itemRenderer ComboBox
Thanks, so this script would go within the
mx:ComboBox...
/mx:ComboBox
Right?
