Is your <script>block ahead of your ScriptManager?

You should place your script code at the end of your page, after all your content but just before the end tag. between end form tag and end body tag Here's the code you need, in its rightful place:
您应该将脚本代码放在页面的末尾，在所有内容之后但在结束标记之前。在结束表单标签和结束正文标签之间这是您需要的代码，在其正确的位置：
<html>
...
</head>
<body>
<form id="form1" runat="server">
...
</form>
enter code here
<script type="text/javascript" language="javascript">
/// <reference name="MicrosoftAjax.js" />
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
function EndRequestHandler(sender, args)
{
ToggleTimeDiv();
}
</script>
</body>
</html>

If you're using ASP.NET routing, use this line in your global.asax
如果您使用 ASP.NET 路由，请在 global.asax 中使用此行
void Application_Start(object sender, EventArgs e)
{
RouteTable.Routes.Ignore("{resource}.axd");
}
