I guess I have a lot of questions here.
1. Any idea why the NestedViewSetting setup I'm using in the above example isn't work?
2. How do you recommend communicating the data key of the Master Table row that is opened to the NestedTableView grid? Is NestedViewSetting not designed to do this? Why does the Telerik example mentioned above use a Label to communicate the data key?
3. Can you illuminate how the HierarchyLoadMode="ServerOnDemand" function work for the Sub Grid? For example, why is the setting ignored or doesn't work if the InnerContainer Panel is initially visible?
