Default.aspx not firing events

Question

We have recently put up a new server with IIS7, where we now have published a .NET4 site.

Locally everything works fine, but on this server the Default.aspx is not working. No events are firing at all for this page. Every other page works as should.

We've tried deleting the Default.aspx and adding a new blank one with just a button event but same thing still applies.

We've spent quite some time troubleshooting this without any results. Same problem exists both with and without using a masterpage.

_{Edited to add:}

After more research it was a module from Telerik that caused it. When disabling RadCompression everything work as intended.

Answer 1

Locally everything works fine

On your local IIS or Cassini?

Check for "AutoWireUpEvent" property in the page directive

Answer 2

That's really weird. Maybe you can try: Find other machines to visit the site, to see if it's working. If you are using IE, go to Internet Options->General->Settings->Check for version of stored pages->Every visit to the page. And even delete all temp files then try.

Problem When RadCompression is enabled and you are using .NET 4.0, event handlers might not be raised in a default document in IIS 7 or IIS 7.5 Integrated Mode.

Solution This problem is caused by a breaking change in .NET 4.0 described here. To workaround it one can set precondition="managedHandler" for the RadCompression module. You may also need to remove the runAllManagedModulesForAllRequests setting from your web.config if you have it (or set it to false).
