Hi All
I’m puzzling with this for a while and now I finally reached a solution!
To make the Tree or List background transparent use the following code:

        mx.controls.treeclasses.TreeRow.[COLOR=#003399]prototype[/COLOR].drawRowFill = mx.controls.listclasses.SelectableRow.[COLOR=#003399]prototype[/COLOR].drawRowFill = [COLOR=#003399]function[/COLOR] (mc:[COLOR=#003399]MovieClip[/COLOR], newClr:[COLOR=#003399]Number[/COLOR]) { 
[COLOR=#ff9900]//Author: Marcelo Quinan <marcelo@aretha.com.br> - [http://www.aretha.com.br](http://www.aretha.com.br/)

[/COLOR] [COLOR=#ff9900]//You can freely use this code, but please don’t remove the credits. Thanks!
[/COLOR] [COLOR=#ff9900]//This code set the list and tree components bg’s to transparent. Put it before populating the components
[/COLOR] switch (mc.[COLOR=#0000cc]_name[/COLOR]) {
case “bG_mc” :
[COLOR=#ff9900]//Alpha when the row is not selected
[/COLOR] [COLOR=#003399]var[/COLOR] tempAlpha = 0;
[COLOR=#003399]break[/COLOR];
case “tran_mc” :
[COLOR=#ff9900]//Alpha when the row is selected
[/COLOR] [COLOR=#003399]var[/COLOR] tempAlpha = 25;
[COLOR=#003399]break[/COLOR];
[COLOR=#003399]default[/COLOR] :
[COLOR=#003399]var[/COLOR] tempAlpha = 100;
}
mc.[COLOR=#003399]clear/COLOR;
[COLOR=#ff9900]//Here’s the trick:
[/COLOR] mc.[COLOR=#003399]beginFill[/COLOR](newClr, tempAlpha);
mc.drawRect(1, 0, [COLOR=#003399]this[/COLOR].__width, [COLOR=#003399]this[/COLOR].__height);
mc.[COLOR=#003399]endFill/COLOR;
mc.[COLOR=#0000cc]_width[/COLOR] = [COLOR=#003399]this[/COLOR].__width;
mc.[COLOR=#0000cc]_height[/COLOR] = [COLOR=#003399]this[/COLOR].__height;
[COLOR=#ff9900]//Hide the main bg of component
[/COLOR] [COLOR=#003399]this[/COLOR].[COLOR=#0000cc]_parent[/COLOR].[COLOR=#0000cc]_parent[/COLOR].depthChild0.[COLOR=#003399]_alpha[/COLOR] = 0;
};

Hope this helps!
