AA,

I am currently using Light Streaming feature using Flex. Every thing is going right except one thing that is I loss the previous data.
I have a webservice that returns some data. I use this data to populate the grid. Then I connect to Light Streamer once i do, the data that was present on the grid gets vanished and the data from Light Streamer server populates on the grid. What I want to do is that I want to keep all the data as it is and when connect to Light Streamer only those columns should be updated whose data is available on the Light Streamer server.
