    AdvancedDataGrid, Hierarchical data, Summary rows

      Hi all,

      I have an AdvancedDataGrid that gets data from an an hierachical XML.

      <mx:AdvancedDataGrid id="MyADG" height="100%" sortableColumns = "false" source="{new HierarchicalData(MyXML)}>

      MyXML is hierarchical (location->department->sub department->revenue). I am trying to create summary rows (for location, dept, sub dept) and all the examples I see talks about getting Flat data, creating grouping collection, group fields and then summary fields.

      Since my data is already hierarchical and grouped , do I still have to group them to create summary fields? I guess the real question is - Does Hierarchical data structure has any advantages when compared to Flat structure, when it comes to creating summary fields? I want to avoid grouping if it is not needed.

      Is there an example that uses hierarchical data and creates summary fields? I would love to see that.

      Thanks a bunch!
