AJAX Suggest / Intellisense / Auto-complete

I am working on an ASP.NET project that uses a dropdown list with so many records that it is not practical to download them all on a page load.  What I have done is created a Google Suggest like Ajax enabled dropdown that pulls records based on the first few characters entered and the number of records returned.  This makes for a much faster page load and better user experience.  I plan on writing up an article and submitting it to www.codeproject.com.  After I right it up I will post a link to it here.  Look for it in the next week….
