Mone No,
There is currently no such event.
Can you expand on your needs so that we may try to suggest an alternative route?
Sure,
We have data populated from a variety of sources (Lightstreamer being one the sources) depending on the service level of the client in question. Firing an event post HTML update allows us to write a single function to perform custom logic both across and incorporating all of these data sources (such as a series of calculations) that will work for all levels of customers.
