Refreshing a layer in silverlight?

[BrandonLand]

Using ArcServer 9.3:   OK, I've created a feature layer in Arcmap that creates points for modems in my system... it's joined to a table that has the ONLINE/OFFLINE status off the modem.   If I launch the app though, and the data changes from OFFLINE to ONLINE, in our old Web ADF .net stuff I pretty much had to do a refresh of the whole page.   Is there any way to have the page (or even WPF) go after/refresh this map without a full reload?

For the moment there is no out-of-the-box 'DataChanged' notification sent by the server to the client.
So, at the client side,  you have to do a full refresh and to write your own web service notifying you of the modem status changes.
