Title Body

What I am trying to accomplish to to get financial data in my Flex Datagrid to be color-coded--green if it's positive; red if it's negative. This would be fairly straightforward if the column I want colored was part of the dataProvider. Instead, I am calculating it based on two other columns that are part of the dataProvider. That would still be fairly straightforward because I could just calculate it again in the ItemRenderer, but another part of the calculation is based on the value of a textBox. So, what I think I need to be able to do is send the value of the textBox to the custom ItemRenderer, but since that value is stored in the main MXML Application, I don't know how to access it. Sending it as a parameter seems like the best way, but perhaps there's another. Here is the current code for my ItemRenderer: package { import mx.controls.Label; import mx.controls.listClasses.*; public class PriceLabel extends Label { private const POSITIVE_COLOR:uint = 0x458B00 // Green private const NEGATIVE_COLOR:uint = 0xFF0000; // Red override protected function updateDisplayList(unscaledWidth:Number, unscaledHeight:Number):void { super.updateDisplayList(unscaledWidth, unscaledHeight); /* Set the font color based on the item price. */ setStyle("color", (data.AvailableFunding >= 0) ? NEGATIVE_COLOR : POSITIVE_COLOR); } } (data.AvailableFunding doesn't exist) So does anyone know how I would go about accomplishing this?
