RE: [flexcoders] Re: How do I reset itemRenderer inside DataGrid when dataProvider is updated?

Can you not overwrite the data property it sets using the override and setting the data of the super to the value and doing what you want?   Override public function set data (value:object):void{ super.data="" cb_planNumber.selected=value.someBoolean// do stuff } From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of ben.clinkinbeard Sent: Tuesday, July 18, 2006 1:01 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: How do I reset itemRenderer inside DataGrid when dataProvider is updated?   Thanks for the reply, Tim. Unfortunately, the selected state is not held in the data. The checkboxes should always begin unchecked, but the user can (obviously) check them. The checkboxes apparently get reused though, not all created every time, because cb_planNumber.selected = false; does not work either.
