The page is performing an async postback but the ScriptManager.SupportsPartialRe
有个asp.net自带的menu控件，点击频繁后就报错The page is performing an async postback but the ScriptManager.SupportsPartialRendering property is set to false. Ensure that the property is set to true during an async postback.
[解决办法]
是不是用了updatepanel了.把menu包裹起来了。
