DropDownList assistance

I'm developing a utility for my company in ASP.Net/VB.Net and I need the page to have auto-complete style DropDownList...  Unfortunately when you click on the DropDownList I've added on the webpage it doesn't allow typing entry to simplify search.  I'm loading the DD via a code based ADO-Teradata query into the DropDownList.  I've searched and found a few C# options and Jquery but they seem very involved for something I think should be simple.  Isn't there a control or something that should allow for ease of item location?  Thanks for any assistance!

There are two answers, if you are comfortable with ASP.net AJAX toolkit, you can check out this link:
http://www.asp.net/ajaxlibrary/AjaxControlToolkitSampleSite/autocomplete/autocomplete.aspx

if you want to build it from scratch(that's not tough either) you can follow this article and replace

    public string[] FindName(string prefixText, int count) 
    {        
        //return all records whose Title starts with the prefix input string         
        List<string> titleArList = new List<string>();         
        SqlDataReader drProducts = sqlProductProvider.GetNameList(prefixText);         
        while (drProducts.Read()) {            
            string strTemp = Convert.ToString(drProducts("Name")); 
            titleArList.Add(strTemp); 
        }   
        return titleArList.ToArray(); 
    } 

Open in new window


with appropriate code.

Actually a regular dropdown will respond to letters entered and as such have a form of autocomplete.

Just try in out, focus on a large dropdown in your browser (sopmething like a country list) and start typing some letters....
