推荐答案

下面是 zhughes 的答案这线程在asp.net论坛。

Here is the answer by zhughes from this thread on asp.net forum.

原因：由ScriptManager的变化时产生的URL路由模块使用的JavaScript的路径

The Reason : the path of the javascript generated by the scriptmanager changes when the URL Routing module is used.

解决方案：给路由API不路由AXD扩展名的文件（通过使用ScriptManager生成的文件）

The Solution : Tell the routing API to not route the files with "axd" extension (the files generated by the scriptmanager)

添加此规则的方法，其中您注册在Global.asax中的路由规则

Add this rule to the method where you register the routing rules in Global.asax

 routes.Ignore("{resource}.axd/{*pathInfo}");

此外，你应该有这个节在web.config中

in addition you should have this section in web.config

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true" />
</system.webServer>
