[flexdev] Re: Ajuda AdvancedDataGrid!

[Chacal Army]

Cara essa semana pesquisei sobre esse componente,
a adobe na documentação dela fornece esse exemplo:

<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";>

    <mx:Script>
        <![CDATA[
            import mx.collections.ArrayCollection;

            [Bindable]
            private var dpFlat:ArrayCollection = new ArrayCollection([
              {Region:"Southwest", Territory:"Arizona",
                  Territory_Rep:"Barbara Jennings", Actual:38865,
Estimate:40000},
              {Region:"Southwest", Territory:"Arizona",
                  Territory_Rep:"Dana Binn", Actual:29885, Estimate:30000},
              {Region:"Southwest", Territory:"Central California",
                  Territory_Rep:"Joe Smith", Actual:29134, Estimate:30000},
              {Region:"Southwest", Territory:"Nevada",
                  Territory_Rep:"Bethany Pittman", Actual:52888,
Estimate:45000},
              {Region:"Southwest", Territory:"Northern California",
                  Territory_Rep:"Lauren Ipsum", Actual:38805, Estimate:40000},
              {Region:"Southwest", Territory:"Northern California",
                  Territory_Rep:"T.R. Smith", Actual:55498, Estimate:40000},
              {Region:"Southwest", Territory:"Southern California",
                  Territory_Rep:"Alice Treu", Actual:44985, Estimate:45000},
              {Region:"Southwest", Territory:"Southern California",
                  Territory_Rep:"Jane Grove", Actual:44913, Estimate:45000}
            ]);
        ]]>
    </mx:Script>

    <mx:Panel title="AdvancedDataGrid Control Example"
        height="75%" width="75%" layout="horizontal"
        paddingTop="10" paddingBottom="10" paddingLeft="10" paddingRight="10">

        <mx:AdvancedDataGrid id="myADG"
            width="100%" height="100%"

            <mx:dataProvider>

                    <mx:grouping>
                        <mx:Grouping>

                <mx:AdvancedDataGridColumn dataField="Estimate"/>

       </mx:AdvancedDataGrid>
    </mx:Panel>
</mx:Application>



Se vc debugar a app vera como fica a estrutura  do  dpFlat, baseando nisso
montei esse exemplo,
pois meus objetos viram sempre de um banco de dados espero que ajude :

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"
creationComplete="montaAdvadataGrid()">
  <mx:Script>
    <![CDATA[
        import mx.controls.Alert;
        import mx.collections.ArrayCollection;
        [Bindable]
           private var arData:ArrayCollection = new ArrayCollection();

         private function montaAdvadataGrid():void{
            for(var i:int=0;i<5;i++){
                var pai:Object = new Object;
                    pai.nome = "Pai " + i;
                for(var j:int=0;j<3;j++){
                        var arrFilhos:ArrayCollection = new
ArrayCollection();
                        for(var h:int=0;h<3;h++){
                            var filho:Object = new Object;
                            filho.nome = "Jao "+i;
                            filho.idade = "10";
                            arrFilhos.addItem(filho);
                        }
                    pai.filhos= arrFilhos;
                }
                arData.addItem(pai);
            }
        }
     ]]>
    </mx:Script>
    <mx:AdvancedDataGrid width="100%" height="100%" dragEnabled="true"
