On Question1 : Can you please point me to a sample where the ASP.NET combo exposes such behavior.
On Question 2:
I would definitely not recommend to use a combo box to perform a search among thousands or millions of items. The control is simply not intended for such purpose.
The combo box search operation may be performed on the client only . This means you will need to load all the thousands/millions items at the client.
This will be heavy both for the client side search and for the service over the wire as transferring millions of items to the client is expected to be slow.
Such operations should be performed at the server - e.g. the user can enter some criteria in a text box , then the server will return a small portion of data displayed in a list so the user can chose from .
If the user knows the exact id - then it may be again entered in a textbox and the server shall return only the required record.
Am I missing something ?
