Abstract—Textbox input is widely used on the web for user input. In order to provide convenience for the web users and increase the input efficiency, one can use AutoComplete feature with the textbox. AutoComplete feature predicts possible word matches for entries that begin with the prefix typed into the textbox without the user actually typing the whole word completely. This paper describes the design and implementation of an ASP.NET application based on AutoComplete Extender control from AJAX Control Toolkit. The textbox control is bound with the AutoComplete Extender and then web service is deployed to connect the database server that stores the possible words. User keystrokes are monitored and textbox input is completed based on first typed letters that match with data stored in database. An AutoComplete test program is developed and tested.
