Why is footer not included in Repeater.Items?

Question

I need to get the value from a text box inside the FooterTemplate in the OnClick event of a button. My first thought was to scroll through the items property on my repeater, but as you can see in this example, it only includes the actual data items, not the footer.

Aspx:

<asp:Repeater ID="Repeater1" runat="server">
    <ItemTemplate>
        Item<br />
    </ItemTemplate>
    <FooterTemplate>
        Footer<br />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </FooterTemplate>
</asp:Repeater>
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />

Code-behind.cs:

protected void Page_Load(object sender, EventArgs e)
{
    ListItemCollection items = new ListItemCollection();
    items.Add("value1");
    items.Add("value2");
    Repeater1.DataSource = items;
    Repeater1.DataBind();
}

protected void Button1_Click(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine(Repeater1.Items.Count);
}

This code will only output “2” as a counter, so how can I get a link to my text box inside the footertemplate?
