You may be better off overriding the set data function in your renderer.
The following is an example I have used in the past to create a
linkButton in a cell if the data is greater than zero or to gray it out
if it is zero:
package renderers
{
import mx.controls.*;
import mx.controls.dataGridClasses.DataGridListData;
public class CellField extends LinkButton
{
private var fieldValue:String;
public function CellField()
{
super();
}
override public function set data(value:Object):void
{
if(value != null)
{
super.data = value;
fieldValue =
value[DataGridListData(listData).dataField];
label = fieldValue;
if (Number(fieldValue) == 0)
{
enabled = false;
useHandCursor = false;
}
else
{
enabled = true;
useHandCursor = true;
setStyle("color", "#FF0000");
setStyle("textDecoration", "underline");
setStyle("textRollOverColor:", "#0000CC");
}
}
}
}
}

however , when i scroll the DataGrid, the row's style is incorrect.
