I am just starting out in ajax. I've figured out how to get the items I need to fill a list in the AutoExtendControl attached to a textbox. That part works fine, and I'm able to enter text, see the drop-down, and then select an item to fill out the textbox. But I am trying to find a quick way to access the index (integer) of the item selected from the list. I need this in order to search a separate list for the same index in order to pull values into other places on the page.
