asp.net - Rad Ajax 加载面板未显示在 asp.net 页面的回发中

Question

我已经在这里工作了几个小时了。我有一个 Aspx 页面，带有几个用户控件。每当我在用户控件上调用任何 javascipt 时， ListView 都会更新但不显示对话框。谁能告诉我原因或任何信息。这是我的代码。aspx页面

用户控制javascript

 var album = $(this).prev().val();
                    $('[id$=AccessChoice]').val(option);
                    $find("<%= RadAjaxManager.GetCurrent(Page).ClientID %>").ajaxRequest(album);

用户控制

<telerik:RadAjaxManagerProxy  ID="FullAlbumAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="FullAlbumAjaxManager1">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="ListViewPanel1" LoadingPanelID="RadAjaxLoadingPanel1" />

Answer 1

这是一个老问题，但我会尝试回答，因为我遇到了同样的问题，这是我的解决方案:

ListView 不会呈现为 HTML 标记(我假设 ListViewPanel1 和 lvFullControlAlbums 是 ListView)，因此您应该将这些控件包装在一个 Panel 并相应地修改 AjaxSettings:

<telerik:AjaxSetting AjaxControlID="FullAlbumAjaxManager1">
    <UpdatedControls>
        <telerik:AjaxUpdatedControl ControlID="ListViewWrapper" LoadingPanelID="RadAjaxLoadingPanel1" />
    </UpdatedControls>
</telerik:AjaxSetting>

<asp:Panel ID="ListViewWrapper" runat="server">
    <asp:ListView ID="ListViewPanel1" runat="server" >
        <!-- your code here -->
    </asp:ListView>
</asp:Panel>

FullAlbumCounter 可能也是一个控件，它本身不呈现为 HTML 标记，仅呈现其内容。在这种情况下，您也应该这样做。
