title: Get The Items Under An Expanded Node in AdvancedDataGrid
body: <p>Is there a way to get the items which are under an expanded ADG tree node?</p>
  
  <p>Given the sample tree node:</p>
  
  <pre><code>- Atlantic
      Celtics
      Nets
      Knicks
      Sixers
      Raptors
  + Central
  + SouthEast
  + SouthWest
  + NorthWest
  + Pacific
  </code></pre>
  
  <p>I am planning to capture the data in the ADG's itemOpen event.</p>
  
  <pre><code>private function myADG_ItemOpen(event:AdvancedDataGridEvent) :void
  {
    // What codes do I put here to get the following teams:
    // Celtics, Nets, Knicks, Sixers, Raptors
  }
  </code></pre>
  
  <p>Update:
  I managed to pull off some codes that somehow provides me an object containing the teams:</p>
  
  <pre><code>var ihd:IHierarchicalData = IHierarchicalCollectionView(myADG.dataProvider).source;
  
      if(ihd.hasChildren(evt.item))
      {
        var objGetChildren:Object = ihd.getChildren(evt.item);
        var dataString:String = ObjectUtil.toString(objGetChildren);
  
        // From here, I am able to parse the dataString to an array, where I am able to get the team name.
      }
  </code></pre>
