I am sure that with as many dashboard apps out there, people have come across this issue. I have a SL app that needs to loop continuously, calling a RIA service to pull in data updates, with some minimal timer delay (e.g. 3 sec). It is an MVVM solution, and the data being refreshed on the client will likely be wrapped in a PagedCollectionView.
Are there any common (tr: tried and tested) approaches to fetching the data the first time and updating/appending new data in this fashion? It is purely read-only data, there is no editing to worry about.
