RE: [Non-DoD Source] Grouping arrayCollection

[Kessler CTR Mark J <ma...@usmc.mil>]

Do you mean using filterFunction[1] to only show one set/group of the rows at a time?


myAC.filterFunction = myFilterFunction;


public function myFilterFunction(item:Object):Boolean
{
    if (String(item.name) == "A")
    {
        //show
        return true;
    }

    //hide
    return false;
}

Subject: [Non-DoD Source] Grouping arrayCollection

Hi All,
I have this array collection:
public var myAC:ArrayCollection = new ArrayCollection([
                                        {name:"A", code:10, fy2014:50, fy2015:100},
                                        {name:"A", code:10, fy2014:150, fy2015:250},
                                        {name:"A", code:20, fy2014:200, fy2015:350},
                                        {name:"A", code:20, fy2014:300, fy2015:450},
                                        {name:"B", code:10, fy2014:100, fy2015:150},
                                        {name:"B", code:10, fy2014:200, fy2015:250},
                                        {name:"B", code:20, fy2014:300, fy2015:350},
                                        {name:"B", code:20, fy2014:400, fy2015:450},
                                ]);
How can I group the ac with totals? like:
                                name, code, t2014, t2015
                                A, 10, 200, 350
                                A, 20, 500, 800
                                B, 10, 300, 400
                                B, 20, 700, 800
Thanks!

Thanks Mark for your reply and help.
The filter only group the data, I did create another array an stored the
summary of the filter result.
Best,
