MultiViewを使用してマルチステップフォームを作成しています。次のボタンは最初のステップ（ViewOne）で機能しますが、次のステップ（ViewTwo）では次のボタンと戻るボタンの両方が何もしません。

以下のコードに手がかりがあるのか​​、もっと見る必要があるのか​​わかりませんか？... 

 <asp:MultiView ID="MultiView2" runat="server" ActiveViewIndex="0">
 <asp:View ID="ViewOne" runat="server">
 </asp:View>
 <asp:View ID="ViewTwo" runat="server">
 </asp:View>
 </asp:MultiView>
 <asp:ImageButton ID="btnBack" runat="server" ImageUrl="/assets/back_button.jpg"  OnClick="btnBack_Click" /> 
 <asp:ImageButton ID="btnNext" runat="server" ImageUrl="/assets/next_button.gif" OnClick="btnNext_Click" />
 <asp:ImageButton ID="btnSubmit" runat="server" ImageUrl="/assets/submit_button.gif" OnClick="btnSend_Click" />

背後にあるコード....

protected void btnBack_Click(object sender, EventArgs e)
    {
        MultiView2.ActiveViewIndex--;
    }

    protected void btnNext_Click(object sender, EventArgs e)
    {
        MultiView2.ActiveViewIndex++;
    }

    protected void btnSend_Click(object sender, EventArgs e)
    {
        OnSubmitClicked(e);
    }

OKもっとコード...

protected override void OnLoad(EventArgs e)
{
        base.OnLoad(e);
     PopulateSomeField();
    }

protected override void OnPreRender(EventArgs e)
    {
        btnBack.Visible = MultiView2.ActiveViewIndex > 0;
        btnNext.Visible = MultiView2.ActiveViewIndex < MultiView2.Views.Count - 1;
        btnSubmit.Visible = MultiView2.ActiveViewIndex == MultiView2.Views.Count - 1;
        base.OnPreRender(e);
    }

そこにエラーはありません。それは私にとってはうまくいきます。
