unordered list help

I've created an user control that contains a unordered list:

<%@ Control Language="vb" AutoEventWireup="false" Codebehind="TopMenuBar.ascx.vb" Inherits="compasslearning.TopMenuBar" TargetSchema="http://schemas.microsoft.com/intellisense/ie5" %>
<table border="0" cellpadding="0" cellspacing="0">
<colgroup align=left width=50% span=1></colgroup>
<colgroup align=right width=50% span=1></colgroup>
<tr>
<td>
<ul>
<asp:Repeater ID="topmenu" Runat="server">
<ItemTemplate>
<li>

</li>
</ItemTemplate>
</asp:Repeater>
</ul>
</td>
<td>
<form name=frmSearch method=POST action="search.asp" style="margin:0px">Search
<input type="text" size="25" name="txtQuery">
<a href="javascript:document.frmSearch.submit()"><img src="images/go.gif" align="absmiddle" border="0"></a>
</form>
</td>
</tr>
</table>

I'm trying to control the visibility of the list in the code-behind

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here

Dim MenuItems As New ArrayList

MenuItems.Add("About Us")
MenuItems.Add("Contact Us")
MenuItems.Add("Customer Support")
MenuItems.Add("Site Map")

Dim topmenu
topmenu.Visible = False
End Sub

I'm getting the following error: Object variable or With block variable not set.
which occurs on the following line: topmenu.Visible = False

I'm going to eventually wrap this in an If statement and turn off the visibility based on a recordset value.

Thanks,

I'm just kind of getting my feet wet with .net.

I was following your code example and think I have a basic understanding your example.

You're defining a new bulleted list
Defining the style of the bulleted list
Defining a new listItem
Creating what each list item would be --- how do you add more than one list item, just add new items seperated by semi-colons?
Add the items to the bulleted list "MyList"
Finally add the control name that can be referenced in the user control.

Am I understanding this correctly?

So, if I want to access that new control, I'd simply use:

<asp:MyList Runat="Server"></asp:MyList>

I hope I understand this correctly.

What are the benefits to handling the development of the list this way rather than the method I was trying? Is there an example I can find using VB.NET?

Thanks for your help.
