RE: [flexcoders] Dynamically highlighting a datagrid row

[Alex Harui]

The highlight works for me in this example:

 

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
verticalGap="0" xmlns:local="*" height="500" >

            <mx:Script>

            <![CDATA[

                        private var arr:Array = [

                                    { enabled: false, selected: false,
firstName: "Alex", lastName: "Harui" },

                                    { enabled: true, selected: true,
firstName: "Gordon", lastName: "Smith" },

                                    { enabled: false, selected: false,

                                    { enabled: false, selected: false,

                        ];

 

            ]]>

Subject: [flexcoders] Dynamically highlighting a datagrid row

 

I've looked for a combobox that drops down a datagrid, but have not
found one so I'm building one that suits my needs. I have my POC
working but after selecting a row in the datagrid and the combobox
closing as it should, then reopening the combobox loses the
hightlighted row in the datagrid. I've successfully reset the
datagrid selectedIndex to what it should be, but I can't figure out
how to highlight that row.

I'm asking for two suggestions:
1. If any one knows of a combobox that drops down a datagrid I'd like
to know about it as I don't like recreating the wheel.

2. Advice on how to dynamically highlight the datagrid row.

Thanks,
Dale
