asp.net - 既製のものにさらにコントロールを追加する

Question

こんにちは私は asp.net で新しく始め
ました。ウェブサイトの構築を開始しましたが、ここで行き詰まりまし た。ユーザー名 n パスワードを受け入れるためのテキスト ボックスを持つ
登録ユーザー コントロールを含む既製のテーマを使用しました。 ユーザー名とパスワード、特に連絡先番号、住所などのコードをコピーして貼り付けることで、さらに 3 つのコントロールを追加しました。

しかし、私が追加したテキストボックスは、ASPX.CS ファイルではアクセスできません!

私は既製のコントロールに次のようにアクセスできます：RegisterUser.UserName
しかし、アクセスしようとするとRegisterUser.Address利用できません

コード：

    <asp:CreateUserWizard ID="RegisterUser" runat="server" EnableViewState="false" OnCreatedUser="RegisterUser_CreatedUser">
        <FinishCompleteButtonStyle BorderStyle="None" />
        <FinishPreviousButtonStyle BorderStyle="None" />
        <LayoutTemplate>
            <asp:PlaceHolder ID="wizardStepPlaceholder" runat="server"></asp:PlaceHolder>
            <asp:PlaceHolder ID="navigationPlaceholder" runat="server"></asp:PlaceHolder>
        </LayoutTemplate>
        <ContinueButtonStyle BorderStyle="None" />
        <WizardSteps>
            <asp:CreateUserWizardStep ID="RegisterUserWizardStep" runat="server">
                <ContentTemplate>
                    <h2>
