Item renderer - Rendering a row in flex - actionscript-3

Question

I have got a datagrid with three columns. I have applied two different renderers on different columns (Say Renderer A at column 1 and Renderer B at column 3).
Now in set Data() of B (column three's renderer) I am changing a Requiredflag on the basis of some condition. In set Data of A (Column 1's renderer), I am checking the RequiredFlag and changing its style accordingly.
The problem is for a Row, A renders before B as it is the first column, so it does not get the updated value of requiredFlag (as the requiredFlag is updated in B).
So can I somehow render the first column's cell again after rendering third column's cell? Or if I can render the whole row again after the value of requiredFlag changes in third column's cell.

Answer 1

See the itemrender as a view, so the renderer itself does not do any computation, just check the value of the object...
If I understood correctly I'll do something like that...
(maybe you need to move the check from set data to updatedisplaylist)
example:
class Test
{
public var col1:String = "Everything";
public var col3:String = "Cars";
public function get color():uint
{
if (col1 == "Everything")
return 0xff0000;
return 0x000000;
}
}
itemrendererA.mxml
override public function set data(value:Object):void
{
super.data = value;
if (super.data != null && super.data is Test)
{
// do what you need to do..
lbl1.text = (super.data as Test).col1;
lbl1.setStyle("color", (super.data as Test).color);
}
}
itemrendererB.mxml
override public function set data(value:Object):void
{
super.data = value;
if (super.data != null && super.data is Test)
{
if ( (super.data as Test).color == 0xff0000)
// do something
else
// do something else
}
}
if that's not what you're looking for, please add some of your code...
