[Solved] cant edit nested hierarchy rows

[mac]

 am experiencing difficulty doing any edits/inserts/deletes on child tables within the grid obj.
using the sample provided that displays hierarchal tables. http://www.telerik.com/demos/aspnet/prometheus/Grid/Examples/Hierarchy/ThreeLevel/DefaultCS.aspx
i removed the third child as it was redundant to the issue - you will note the allowAutomaticUpdates is enabled, along with the gridEditCommanColumn.  thoughts on why this would not work?

duhhh...
don't forget to add the DataKeyNames to the GridTableView you are editing on.

<telerik:GridTableView  DataKeyNames="your Key ID"  VirtualItemCount="100"
                            CommandItemDisplay="TopAndBottom"
                            DataSourceID="AllApps"
                            runat="server" AutoGenerateColumns="False">
