Answer 2

+1 A:

If I understand correctly you want some form of autocomplete as the user types in your input box.

To achieve this you should use ajax, and the ASP.Net Ajax Toolkit might be what you are looking for. Check out the sample and docs at http://www.asp.net/ajax/ajaxcontroltoolkit/samples/autocomplete/autocomplete.aspx.

Here's a sample for VS2010 and using ASP.Net Toolkit 4.

    {  
        if (count == 0)  
        {  
            count = 10;  
        }  
        if (prefixText.Equals("xyz"))  
        {  
            return new string[0];  
        }  
        Random random = new Random();  
        List<string> items = new List<string>(count);  
        for (int i = 0; i < count; i++)  
        {  
            char c1 = (char)random.Next(65, 90);  
            char c2 = (char)random.Next(97, 122);  
            char c3 = (char)random.Next(97, 122);  
            items.Add(prefixText + c1 + c2 + c3);  
        }  
        return items.ToArray();  
    }  
}
