Ajax Control ToolKit

Ajax toolkit doesn't work with MVC because it was built for WebForms. You have to use alternative technology for that purpose such as "jQuery".

For example: http://www.codeproject.com/Tips/639578/jQuery-Autocomplete-MVC-and-WebAPI

Bunos: search the term "jQuery Autocomplete example in MVC" at google to get more examples.
