That's the hyperlink I (and I think everyone else that has responded) is
trying to hide.

You cannot hide an ItemTemplate (because it's just a template), so you
need to either hide the list item <li> or the hyperlink itself for a
specific bound item.

If you really only want to hide the hyperlink, replacing the hyperlink
with this works (I tested):

<asp:HyperLink 
        runat="server" 
        NavigateUrl='<%# Eval("Url") %>' 
        Visible='<%# (!String.IsNullOrEmpty((string)Eval("Url"))) %>'
> <%# Eval("Title") %> 
</asp:HyperLink>

(I missed the cast to a string in my above code, which is why it
probably failed last time)


If you *actually* want the list item (the <li>)removed from the <ul>
list, then you need to use similar logic to hide the <li> tag:

<li 
        runat="server" 
        visible='<%# (!String.IsNullOrEmpty((string)Eval("Url"))) %>'>
     <asp:HyperLink 
                runat="server" 
                NavigateUrl='<%# Eval("Url") %>' 
                >  <%# Eval("Title") %> </asp:HyperLink>
</li>
