如果在更新面板的服务器端捕获到异常，您能以某种方式看到堆栈跟踪吗？

protected void ScriptManager1_AsyncPostBackError(object sender, AsyncPostBackErrorEventArgs e)
{
        //do something with the exception
        log(e.Exception.Message);

        // show a message to the user.
        ScriptManager1.AsyncPostBackErrorMessage =
            \"An  error occurred.\" + e.Exception.Message;
    }
}
