C#
C# ,c#,javascript,asp.net,ajax,C#,Javascript,Asp.net,Ajax,如果我使用frm.Controls.Add（tblOne）而不是frm.Controls.Add（divContent），那么它可以正常工作，因为tblOne没有Ajax控件。但是divContent既有表也有Ajax控件，它抛出上述异常。我尝试了很多选项，比如覆盖OnInit和OnPreRender，但对我来说不起作用 这可能是由于在代码中放置了ToolkitScriptManager。看看这是否解决了您的问题： 最后，我通过使用JavaScript代码解决了这个问题&对我来说效果更好，我要感
如果我使用
frm.Controls.Add（tblOne）frm.Controls.Add（divContent）tblOnedivContentOnInitOnPreRender最后，我通过使用JavaScript代码解决了这个问题&对我来说效果更好，我要感谢所有给我宝贵时间和反馈的人。 代码如下：
<script>
function Panel1() {
var panel = document.getElementById("<%=printablediv.ClientID %>");
var printWindow = window.open('', '', 'height=400,width=800');
printWindow.document.write('<html><head><title>newTable</title>');
printWindow.document.write('</head><body >');
printWindow.document.write(panel.innerHTML);
printWindow.document.write('</body></html>');
printWindow.document.close();
setTimeout(function() {
printWindow.print();
printWindow.close();
}, 1000);
return false;
}
</script>
功能面板1（）{
var panel=document.getElementById（“”）；
var printWindow=window.open（“”，’高度=400，宽度=800’）；
printWindow.document.write（'newTable'）；
printWindow.document.write（“”）；
printWindow.document.write（panel.innerHTML）；
printWindow.document.write（“”）；
printWindow.document.close（）；
setTimeout（函数（）{
printWindow.print（）；
printWindow.close（）；
}, 1000);
返回false；
