UpdatePanel 服务器反应慢
我有一个更新面板，当我单击复选框时，它会显示或隐藏新控件。但问题是速度非常慢。从点击复选框到视觉反应发生几乎2秒就过去了。
我认为这是由于异步回调造成的。客户端似乎在每次回调触发之间等待 1-2 秒。这是真的吗？如果是，是否有一个设置可以使服务器回调立即发生？
编辑 看来我遇到了一个已知的错误，但提供的修复对我不起作用： http://support.microsoft.com/?kbid=2000262
I have an updatepanel which displays or hides a new control when I click a checkbox. But the problem is that is is very slow. From the click of the checkbox until the visual reaction occurs almost 2 seconds are gone.
I think this is due to the asynchonous callback. The client seem to wait 1-2 between each callback to fire. Is this true? If yes, is there a setting which makes callbacks to the server occur in instant time?
EDIT It seems i've hit a known bug, but the offered fix doesn't work for me:
