Hi Raj,
Take a look at the section of the wiki entitled, "Clone, Create and Delete Things." You'll likely need a Service to create Things from your Mashup and then the Service that is populating your Tree widget will need to be executed whenever you create a new Thing. The easiest way to do this would be to use the
ServiceInvokeCompleted
Event of the
Service creating
Things to execute the
Service that is returning a list of
Things.
