Hi.
I am using item renderer for DataGrids column (for example) derived
from DataGridItemRenderer. The data sent to item renderer has a
boolean property named "valid". If valid == true I want the label to
be red otherwise black. The problem is when I'm using direct
assignment textColor = 0xFF0000; the text doesn't become red. When I'm
using data binding (with data.valid == false) like
<mx:DataGridItemRenderer ... textColor="{highlightColor}">... Where
highlightColor is, for example:
[Bindable]
public var highlightColor : Number;
public override function set data(value : Object) : void {
if (value != null && value.valid) {
highlightColor = 0x000000;
} else {
highlightColor = 0xFF0000;
}
super.data = value;
}
the text still DOESN'T become red.
However if to derive renderer from any container, say Canvas, and
insert Label into that container like:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml";>
<mx:Label color="{highlightColor}" ... />
</mx:Canvas>
with the same highlightColor everything works -- text DOES become red.
I've faced the same behavior in many situations related to item
renderers and list-based controls. E.g. CheckBox or RadioButton need
to be initially checked inside of a list. Every time had to use this
"itemRenderer = control inside of a container + bindable data;"
approach to make it work.
Can't understand why... Seems to me that described above approach is
way to strained. There should be more native one.
Appreciate any help,
R.
