Question

I have a form that auto-completes from a database containing 2000+ and growing names. This works fine, but there’s an annoying lag between when the user types and when the list is returned. I want to store the data temporarily during the lifetime of the page to speed things up.

Using static variables seems to work, but I’m scared of the auto-complete variable becoming out of date. Is there something else I could use?

You can use the Caching.Cache class to hold the values – when you insert to the cache, you can set the item to expire using a TimeSpan, or depending on the version of SQL Server, you could use SqlDependency directly with it to track changes in the DB.
