On C#.net 2010 new in asp.net and desktop applications, I am suppose to have a 'type ahead' feature. Basically a user 'starts' to type a 'company name' in a text box, and then the application comes up with options on what the user is trying to enter. This way the user does not have to enter the entire company.

I do not know what this option occurs in C#.net 2010. Can you explain this to me and/or point me to a url that would explain this option to me?
