Hi,

If you'd like to handle every message rised by LS web client you should implement both PushPage and LightstreamerEngine callbacks. Please refer to the API docs for a full overview of the kind of messages you can get from the various callbacks: http://www.lightstreamer.com/docs/cl...doc/index.html
and get back if something is unclear.

Find below a list of "messages callbacks" for your convenience:
