I cranked up some code to make a google suggest like functionality using AJAX. Check out the image below:

Although its not perfectly working but you can get an idea how the things work and you can enhance it.
Here is the JavaScript code:
<script language = "javascript">
function GetWords(pressevent,myVal)
{
var charCode = (pressevent.which) ? pressevent.which : (event.keyCode);
// Check for the enter key
if(charCode!= 13)
{
ForumsQuestions.FillList(myVal,GetWords_CallBack)
if(charCode == 32)
{
// Put the value from the from the DIV into the TextBox
var word = document.getElementById("MyDiv").innerHTML;
document.getElementById("MyTextBox").value = word.substring(0,word.length - 4);
}
}
}
function GetWords_CallBack(response)
{
if(response!=null)
{
document.getElementById("MyDiv").innerHTML = response.value;
}
}
