Click on advanceddatagrid having dataprovider as grouping collection

Question

I am creating tree structure using advanceddatagrid. The dataprovider is grouping collection whose source is arraycollection. This grouping collection is grouping the fields as specified and I am getting the right tree structure.

I have this type of tree structure

Client
      Fund
          Account

Whenever user clicks on any of these node there is click handler which is as follows:

          private function clickhandler(event:Event){

           var item:VO=event.currentTarget.selectedItem as VO
           Alert(item.ID);
          }

Where VO is a bean class whose fields are

  ID
  Name

When I click on Account node I am getting the right alert value(according to above function) but when I click on fund or client I am not getting value in alert. It says error as Type error:#1009 cannot access the property

So here when I click on leaf node I am getting the data source value which are associated to that node but when I am clicking non leaf node I am not getting the data source values like (as in above function VO.ID and VO.Name). How to get it solved?

Second question: Also I want to know that on which level user has clicked in the tree that is level 1(client) or level 2(fund) or level 3(account).

Try to create your own AdvancedDataGridGroupItemRenderer and AdvancedDataGridItemRenderer

<mx:AdvancedDataGrid 
itemRenderer="MyAdvancedDataGridItemRenderer"
groupItemRenderer="MyAdvancedDataGridGroupItemRenderer">
</mx:AdvancedDataGrid>

In classes MyAdvancedDataGridItemRenderer and MyAdvancedDataGridGroupItemRenderer create click handlers in this handlers set breakpoints and debug. I think it helps you understand nodes
