有没有办法更新 jquery 对话框中的 gridview？我已经让按钮正常工作，但是 gridview 没有更新。下面是我的代码。

JS：

    <script type="text/javascript" language="javascript">

$(document).ready(function () {

    function BindEvents() {


        //alerts dialog
        $( "#pnlAlerts" ).dialog({            
            autoOpen: false,
            modal: true,
            width: 700,             
            open:function(){{
                $(this).parent().appendTo($("form:first"));
            }}

        });

        $('.openAlert').click(function () {        
            $( '#pnlAlerts' ).dialog( 'open' );
        });
          }

    BindEvents();

});

前端：

            <asp:Panel runat="server" ID="pnlAlerts" Visible="true" class="alert-dialog">

            <asp:UpdatePanel ID="updPanelAlert" runat="server" >
                <ContentTemplate>
                    <asp:Label id="lblDatabaseStatus" runat="server" CssClass="left found" />

                    <asp:Panel id="pnlAlert" Runat="Server" Visible="true">

                        <div id="table-search">

                            <div class="nip">

为了让 GridView 更新，您需要让页面触发回发或对 GridView 上的 DataBind 进行服务器端调用。

您可以尝试的另一个选项是在更新面板中添加一个隐藏按钮，然后调用：

__doPostBack('<%= Button.ClientID %>','');

这应该刷新更新面板，从而刷新 GridView。

您刚刚打开和关闭面板“pnlAlerts”作为模式对话框的 jquery。

如果要在 GridView 中编辑数据，则需要 EditTemplates。

希望有帮助。
