I bind a WebHierarchicalDataGrid to a List<MainItem>.  "MainItem" is my custom object and has List<SubItem> member which is initially not populated.  

I want to be able to expand "MainItem" rows and get subitems only when it is needeed.  I don't want to prepopulte the list of subitems on initial databind.

Please provide an example.

Thank you.
