ASP.net add item underneath menu

Im trying to create some code that will add a list of accounts to the menu item 'Accounts' but I want to do it in code, as i want this to be generated in code.

Problem is I keep getting the message:-
Value of type 'System.Web.UI.Control' cannot be converted to 'System.Web.UI.WebControls.MenuItem'.

Does anyone know how I can correct my code to create an item underneath the 'Accounts' menu?

Thanks in advance!!!!

ASP.net Code:-
---------------------------------------------
                <asp:LoginView ID="lvMenu" runat="server">
                    <LoggedInTemplate>
                        <asp:Menu ID="NavigationMenu" runat="server" CssClass="menu" EnableViewState="false" IncludeStyleBlock="false" Orientation="Horizontal">
                            <Items>
                                <asp:MenuItem NavigateUrl="~/Default.aspx" Text="Accounts" Value="Accounts">
                                    <asp:MenuItem Text="New Item" Value="New Item"></asp:MenuItem>
                                </asp:MenuItem>
                                <asp:MenuItem NavigateUrl="~/transactions.aspx" Text="Transactions" 
                                    Value="Transactions"/>
                                <asp:MenuItem Text="Statments" Value="Statments"></asp:MenuItem>
                            </Items>
                        </asp:Menu>    
                    </LoggedInTemplate>
                </asp:LoginView>



VB.net Code
---------------------------------------------
    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim homeMenuItem As New MenuItem
        homeMenuItem = CType(lvMenu.FindControl("NavigationMenu"), MenuItem).Items(0)

        Dim newSubMenuItem = New MenuItem("Acc1")
        homeMenuItem.ChildItems.Add(newSubMenuItem)
    End Sub

Ive read an article at

Which seems to point to using the code such as:-
Dim homeMenuItem As New Menu
homeMenuItem = CType(lvMenu.FindControl("NavigationMenu"), Menu)

Dim parentItem As New MenuItem
parentItem = homeMenuItem.FindItem("Accounts")

Dim menu1 As New MenuItem
menu1.Text = "Alliance and Leicester"

parentItem.ChildItems.Add(menu1)

But still get the error message:-
"Object reference not set to an instance of an object." on the line "parentItem = homeMenuItem.FindItem("Accounts")"

It seems to this is fine

Dim homeMenuItem As New Menu
homeMenuItem = CType(lvMenu.FindControl("NavigationMenu"), Menu)

Dim parentItem As New MenuItem
parentItem = homeMenuItem.FindItem("Accounts")

Dim menu1 As New MenuItem
menu1.Text = "Alliance and Leicester"

parentItem.ChildItems.Add(menu1)

Hmm, still doesnt work!!!

Think I may have found the issue, but again no idea how to fix it!

The asp:menu is actually on the site.master page, and the code is in site.master.vb but it cannot find the menu control in the site.master!

Any ideas?
