无法获得多视图控制以更改视图

Question

我有一个多视图控件，有两个视图。 View1是默认视图，View2是新视图。当最终用户单击按钮时，我想将视图更改为View2。无论如何，我似乎无法实现这一点。

ASP.NET代码：

<asp:MultiView ID="MVOrder" runat="server">
    <asp:View ID="VOrderNow" runat="server">
        <asp:UpdatePanel ID="UpdatePanel2" runat="server">
            <ContentTemplate>
                <table>
                    <tr>
                        <td>
                        <asp:Label ID="LblInfo" runat="server"></asp:Label>
                        </td>
                        <td>
                        &nbsp;</td>
                        <td>&nbsp;</td>
                    </tr>
                    <tr>
                        <td>
                        <asp:Label ID="LblDrink" runat="server"></asp:Label>
                        </td>
                        <td></td>
                        <td></td>
                    </tr>
                    <tr>
                        <td>
                        <asp:Label ID="LblItemInfo" runat="server"></asp:Label>
                        </td>
                        <td>
                        &nbsp;</td>
                        <td>&nbsp;</td>
                    </tr>
                </table>
                <br />
                <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
            </ContentTemplate>
        </asp:UpdatePanel>
    </asp:View>
    <asp:View runat="server" ID="VOrderComplete">

    <table class="auto-style1">
        <tr>
            <td>&nbsp;</td>
            <td>
            <asp:Label ID="LblOrderComplete" runat="server"></asp:Label>
            </td>
            <td>&nbsp;</td>
        </tr>
        <tr>
            <td>&nbsp;</td>
            <td>
            <asp:Label ID="LblOrderNumberAgain" runat="server"></asp:Label>
            </td>
            <td>&nbsp;</td>
        </tr>
        <tr>
            <td>&nbsp;</td>
            <td>
            <asp:Label ID="LblOrderTimeAgain" runat="server"></asp:Label>
            </td>
            <td>&nbsp;</td>
        </tr>
    </table>

    </asp:View>
<br/>
</asp:MultiView>

按钮单击事件代码：

protected void Button1_Click(object sender, EventArgs e)
        {
            //MVOrder.ActiveViewIndex = 1;
            MVOrder.SetActiveView(VOrderComplete);
        } 

页面加载代码：

if (!IsPostBack)
{
    MVOrder.SetActiveView(VOrderNow);
}

有人可以告诉我我做错了吗？

我认为您可能有一些额外的代码可能会导致此操作无法正常运行。但根据您展示的内容，这将发布并更新您的观点：

<asp:UpdatePanel ID="UpdatePanel2" runat="server">
    <ContentTemplate>
        <asp:MultiView ID="MVOrder" runat="server">
            <asp:View ID="VOrderNow" runat="server">
                <table>
                    <tr>
                        <td><asp:Label ID="LblInfo" runat="server" Text="asdfasdfasdf"></asp:Label></td>
                        <td>&nbsp;</td>
                        <td>&nbsp;</td>
                    </tr>
                    <tr>
                        <td><asp:Label ID="LblDrink" runat="server" Text="lmnoplmnop"></asp:Label></td>
                        <td></td>
                        <td></td>
                    </tr>
                    <tr>
                        <td><asp:Label ID="LblItemInfo" runat="server" Text="iteminfo"></asp:Label></td>
                        <td>&nbsp;</td>
                        <td>&nbsp;</td>
                    </tr>
                </table>
                <br />
                <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />

                        <td>&nbsp;</td>
                    </tr>
                    <tr>
                        <td>&nbsp;</td>

                    </tr>
                    <tr>
                        <td>&nbsp;</td>

                </table>
            </asp:View>
            <br />
        </asp:MultiView>
    </ContentTemplate>
</asp:UpdatePanel>
