Rad Ajax加载面板没有出现在asp.net页面的回发中

Question

我现在已经在这几个小时了.我有一个Aspx页面,有几个用户控件.每当我在用户控件上调用任何javascipt时listview更新但不显示对话框.任何人都可以告诉我为什么或任何信息.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

    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="FullAlbumAjaxManager1">

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并且lvFullControlAlbums是ListViews),因此您应该将这些控件包装在一起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>

可能FullAlbumCounter也是一个控件,它本身不会仅仅作为HTML标记呈现其内容.在这种情况下,你应该这样做.
