Dynamic Data Linq to SQL Website Layout. Field template help!

Hi I am somewhat new to ASP.NET and also a Computer Science Student. Currently I am just doing some self learning here.
 
I have made a Dynamic Data Linq to SQL website, that was made from the C# website templates. Followed the scaffold tutorials, http://www.asp.net/web-forms[^]
I tried to follow the tutorial for the Modifying the Dynamic Data Fields. It showed a demo for getting the date picker widget.
 
I am trying to do something similar but with the autocompelte widget. I don't know how to create the data and which type of data to create. Or where to put the data, also I am having trouble seeing some progress to see if I am actually getting the widget to work. Also I want to do this to only one of my fields. Any snippets I should try to get the widget to work or any advice I could try to do to get this? Sorry for asking for "give me that code". But I am really clueless. This was already in the Dynamic Data website template. And the tutorials told me to mess with this which I am not sure how to do.

<%@ Control Language="C#" CodeFile="Text_Edit.ascx.cs" Inherits="Text_EditField" %>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# FieldValueEditString %>' CssClass="DDTextBox"></asp:TextBox>
 
<asp:RequiredFieldValidator runat="server" ID="RequiredFieldValidator1" CssClass="DDControl DDValidator" ControlToValidate="TextBox1" Display="Static" Enabled="false" />
<asp:RegularExpressionValidator runat="server" ID="RegularExpressionValidator1" CssClass="DDControl DDValidator" ControlToValidate="TextBox1" Display="Static" Enabled="false" />
<asp:DynamicValidator runat="server" ID="DynamicValidator1" CssClass="DDControl DDValidator" ControlToValidate="TextBox1" Display="Static" />
