More specifically, here's what I'm trying to change the viewState in
my itemRenderer when the DataGrid's textfield is edited. But in
order to do that, I need to somehow get an instance reference to my
renderer component. And nothing I've done seems to work...
?xml version=1.0?
mx:Application xmlns:mx=http://www.adobe.com/2006/mxml;
xmlns:comp=components.*
verticalAlign=top horizontalAlign=center
layout=absolute
mx:Script
![CDATA[
import components.imgReset;
import mx.collections.ArrayCollection;
import mx.events.DataGridEvent;
import mx.controls.Alert;
[Bindable]
public var choices:ArrayCollection = choices = new
ArrayCollection([
{resetImage: images/reset.png, fieldName: Smalltown},
{resetImage: images/reset.png, fieldName: Bigtown},
]);
private function changeRendererState(event:DataGridEvent) : void
{
// I can get the rowIndex and columnIndex for the renderer,
// but I don't exactly how to use them to get to the
renderer object...
Alert.show(event.rowIndex + , + (event.columnIndex - 1));
// I just want to get the renderer instance...
// First, there's a problem with my typecasting ??
// Second, there's no such thing as a row property on
// the DataGrid, but I really want there to be...
var RendererInstance:imgReset = imgReset(this.myGrid.columns
[event.columnIndex-1].row[event.rowIndex].itemRenderer);
// Now I want to manipulate renderer instance
properties/states...
RendererInstance.currentState = 'showReset';
}
]]
/mx:Script
mx:DataGrid id=myGrid
editable=true
dataProvider={choices}
itemEditEnd=changeRendererState(event)
mx:columns
mx:DataGridColumn dataField=resetImage
headerRenderer=components.HeaderReset
itemRenderer=components.imgReset/
mx:DataGridColumn dataField=fieldName
editable=true width=230
headerText=Field Name /
/mx:columns
/mx:DataGrid
/mx:Application
I'd sure appreciate some help on this conundrum.
Many Thanks,
Bruce

I have simple datagrid with 2 columns and 2 rows like this:
column 0 column 1
-
imagetextfield
imagetextfield
Column 0 contains my ImageRenderer component.
Column 1 contains the DataGrid's default item renderer and editor:
text, textfield.
First Problem:
How do I identify/get a reference to a particular instance of my
ImageRenderer from, say, column[0], row[1]?
Second (related) Problem:
How do I get the ImageRender instance that corresponds to the row
of
the textfield that fires an event when edited?
I've been wrestling with this problem for days now, and I just
can't
seem to get a grasp on the communication/eventing infrastructure
that's probably necessary to pull this off. Please help.
Thanks,
Bruce
