jquery对话框中的多个回发问题

我正试图在jquery对话框中加载一个aspx页面并执行多次回发。在正在加载的aspx页面中有一个更新面板、网格视图和提交按钮。如果单击"提交"，数据库将进行搜索，数据将显示在gridview中。工作良好。但是，如果再次单击该按钮，则会出现页面错误。页面脚本管理器状态问题。

JQuery代码

function PopUpSearch() {
        $("popupcontainer").empty();
        $("#popup").load("/UI_Reference/SubAccountSearchPopUp.aspx").dialog({     autoopen: false, modal: true, width: 700,             
            open: function (type, data) {
              $(this).parent().appendTo("popupcontainer");               
            }
        });            
        return false;
    }

Div在调用页面加载对话框

<div id="popupcontainer" style="display:none">  
<asp:ScriptManager ID="ScriptManagerPopup" runat="server" ScriptMode="Release">
</asp:ScriptManager>
<div id="popup" style="display:none">
</div>
