A fast, lightweight, easy to integrate auto-suggestion box powered by javascript and wrapped in an easy to use ASPx user control.

Features:

1. Populate any text box with suggestions offline (embedded array) or online (AJAX).
2. Supports multiple suggestions via a comma deliminator.
   
3. Quick and easy to integrate into your project.
4. Compatible with all major browsers and supported by the author.

Where to use this:

        I.      Can be integrated into search pages, i.e. user-search, country-search.

      II.      Where you once had a drop down with 200+ items, you can now use an auto-suggest enabled textbox instead.

    III.      Potential to run multiple searches by using comma’s to separate each query.

    IV.      Useful for use in contact forms when you need to notify or email many users.

I’ve setup a demo which contains a user control TextAutoSuggest which does all the work. All you need to do is focus on loading the control’s DataSource property with a List<of-strings> from which ever source you choose and then call the controls Databind() method.

The included auto suggestion control is powered by Dmitry Khudorozhkov’s auto-suggest java script.
