Question

我已经在这里呆了几个小时了。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和lvFullControlAlbums是ListViews），因此您应将这些控件包装在Panel中并修改AjaxSettings相应地：

<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，它本身不会仅作为HTML标记呈现其内容。在这种情况下，你应该这样做。

希望它有所帮助。

Answer 2

在其中一个ajax设置中应该有AjaxManager1而不是FullAlbumAjaxManager1

Rad Ajax加载面板没有出现在asp.net页面的回发中
