Hi Flexing,
Thanks for the reply!
Yes I already set my itemrenderers in actionscript using:
column.itemRenderer = new ClassFactory
(com.lehman.smd.util.ValueRenderer);
for all my columns.
My problem is inside the itemRenderer component, I do not know the name
of the column that invoked it, so do not know which column value to pick
and render
Eg this is my renderer:
------------------------
<?xml version="1.0" encoding="utf-8"?>
<mx:Text xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> " text="{formatValue(data)}"
color="{signColor}">
<mx:Script>
<![CDATA[
import mx.formatters.NumberFormatter;
[Bindable]
public var signColor:int;
public function formatValue(data:Object):String
{
var value:Number = Number(data.<Do Not Know Which Column Name To Use
As Many Columns Render Using This > );
if(value < 0)
{
signColor = 0xff0000;
}
else
{
signColor = 0x000000;
}
return numFormat.format(value);
}
]]>
</mx:Script>
<mx:NumberFormatter id="numFormat" rounding="nearest"
useThousandsSeparator="true"/>
</mx:Text>
--------------------------
where data =
<resultdetail>
<col1>
"1234.5"
</col1>
<col2>
"-5342"
</col2>
</resultdetail>
Many Thanks,
Aman

Subject: Re: [flexcoders] One Item Renderer Component for Multiple
Columns in a DataGrid - How to find name of column being rendered?
You need to use Action-Script to set the column renders:
var colRendererFactory:ClassFactory = new ClassFactory(columnRenderer);
colRendererFactory.properties = {columnName:"mycol1"};
column1.itemRenderer = colRendererFactory
var colRendererFactory2:ClassFactory = new ClassFactory(columnRenderer);
colRendererFactory2.properties = {columnName:"mycol2"};
column2.itemRenderer = colRendererFactory2;
Hope this helps.

Hello,
I have many columns in my DataGrid that have similar values and
I need to render them in a similar manner.
So I wish to write just one itemRenderer component and set that
as the renderer of all these columns.
So I believe each column will invoke my renderer when my grid
shows up.
However, the default data that is passed to the itemRenderer is
just the XML notation of one single row that is currently being
renderered in the grid.
I do not have any information regarding which column actually
invoked my renderer so do not know which value to use.
Eg all my columns have the same component registered as their
itemRenderer and this is what I get in the "data" variable:
<resultdetail>
<col1>
"1234.5"
</col1>
<col2>
"-5342"
</col2>
</resultdetail>
Now in my renderer I want to format the number but I do not know
which column invoked it and so which value to pick.
Is there anything passed to the renderer that tells the header
of the column which is being currently rendered by the custom
itemrenderer?
I do not want to write renderer_col1, renderer_col2 etc as the
columns and their dataprovider are dynamic.
Many Thanks,
Aman
