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>
<!--<%# DataBinder.Eval(Container.DataItem, "Item") %>-->
</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,
-D-

My Advice to you would be, to steer away from using HTML controls to achieve this, as ASP.NET provides you with all the functionality you need. Here is an example of how I create this in ASP.NET C# Code Behind

        BulletedList MyList = new BulletedList();
        MyList.BulletStyle = BulletStyle.Numbered;
        ListItem MyItem = new ListItem();
        MyItem.Text = "BulletNumbered";
        MyList.Items.Add(MyItem);
        form1.Controls.Add(MyList);

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.
