Extending the Atlast AutoComplete Extender

I have been looking at the new “Atlas” controls, which MS has brilliantly (sarcasm) decided to rename “ASP.NET AJAX”.

The one control I have been most interested in is the autocomplete extender.

I want to use something like this, not to help populate a textox, but instead to allow the user to type a few characters in to narrow down the list of options, rather than showing them a dropdown of 10,000 items.

In otherwords, when they are done with the control, I don’t want the text in the textbox, I want the database ID value behind it, and i also don’t want to let them type in just anything they want, but rather limit their options to what is in the autocomplete options.

I found another blog post where someone is extending the autocomplete behavior:
