The live demo can be seen at:
When launched, this Silverlight application connects to a Lightstreamer Server and subscribes to 30 stock quotes. The data is delivered in real time, via a streaming/push connection, from the Server to the Browser, based on the highly optimized Lightstreamer protocol (with bandwidth management, dynamic throttling, data conflation, delta delivery, etc.).
A Silverlight Grid is used to display the real-time data and a "highlight & fade" effect is used to show changed data, as usual in typical dealing/trading applications. You can sort on any columns and drag the columns around.
If the application is disconnected, it will try to reconnect to the Server automatically and will resubscribe to the items, without need for any user's action.
This is a basic example, with full source code, which should work as a starting point for implementing your own real-time Silverlight applications.
The source code will be released as part of the new Lightstreamer 4 distribution, codename "Duomo". In the meanwhile, if you want to check out the code, please send an email to firstname.lastname@example.org and we will send you.
At the same time, we have released a new version of the Lightstreamer .NET Demo, which is similar to the Silverlight Demo but is based on the .NET Framework. You can find more details on our online demo page.
