display long list of data

Question

I'm developing an intranet app that requires the user to select from a long list of data, approx 55,000 entries. I've tried using a dropdown list, but this takes too long to load. I tried spliting it up alphabetically and using Ajax cascading ddl, but hit a limit of 975 elements and I don't know how to go around this. Any ideas? or "how to's"?

Personally I'll not show more than 200 items at a time. No person can get an overview of just 200 items being displayed at once. I realize that your customer may have set different requirements, but they're also open to logical arguments.

What I would do in your case, without knowing more specifics, would be to use a popup where an user can input a filter/search string and then show 10-50 items and use paging.

How would you go about that? I had offered at text box, but they told me that spelling was a problem.

True spelling can be an issue. In that regard I would suggest you look into Fuzzy Search, I've never used fuzzy search with a database myself, but I found this article through google, assuming you're using SQL server.
