Track Views and Tables on MSSQL

Question

Hi,
I got a table in MSSQL which keeps updated almost every second from another software (Stock Prices).

I need to create a WPF Application with a grid that shows a View from MSSQL. (view is just a complex query with inner joins on the stock table and some other tables).

But since the View keeps updated, I can't really do "SqlDataAdapter.Fill(ds)" every second.

So far; I've heard about the following techniques..

SQL-Dependency
Push Subscription combined with Bindable-LINQ
SQL StreamInsight.
SQLstream.com

Which one is the proper way to achieve this?

Thanks

Using triggers, write the affected entity ids to a push notification queue table
Using SQL service broker, send notifications from the queue table to a notification server to which all end clients are connected
Distribute push notification events for batches of affected entityids from the notification server to all connected clients
The client re-enquires against the view for the affected entities and updates the UI accordingly (remove any deleted, update any changed, insert any new)
It works well.
