Question

有没有办法获取扩展的ADG树节点下的项目？

给定样本树节点：

- Atlantic
    Celtics
    Nets
    Knicks
    Sixers
    Raptors
+ Central
+ SouthEast
+ SouthWest
+ NorthWest
+ Pacific

我打算在ADG的itemOpen事件中捕获数据。

private function myADG_ItemOpen(event:AdvancedDataGridEvent) :void
{
  // What codes do I put here to get the following teams:
  // Celtics, Nets, Knicks, Sixers, Raptors
}

更新：我成功地提取了一些代码，这些代码以某种方式为我提供了一个包含团队的对象：

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.
    }

您可以从AdvancedDataGridEvent获取ADG，然后您可以尝试将其dataProvider投射到IHierarchicalCollectionView。如果可行，您可以使用它来获取opend节点的子节点。

private function myADG_ItemOpen(event:AdvancedDataGridEvent):void
{
    var grid:AdvancedDataGrid = AdvancedDataGrid(event.currentTarget);
    var dataProvider:IHierarchicalCollectionView = grid.dataProvider as IHierarchicalCollectionView;

    if (dataProvider && event.item)
    {
        var children:ICollectionView = dataProvider.getChildren(event.item);

        if (children)
        {
            // do something with the children
        }
    }
}
