How do I implement a Push-Pull web application

Question

The data is either in files or databases.

I want to implement data grids which will pull data from files (either .h5, csv or xml) and sql server database and show them being updated in real time.

I don't want to implement a timer which has few seconds interval. I want to implement a pull push technology in asp.net/c#/silverlight which I could use?

Please guide how best to implement it and if there are any libraries available that I can use?
