On Visual Studio.NET 2010/localhost, an ASP.NET page developed with Devexpress editor and textbox controls looks nice. When uploaded to IIS 7.5, the generated html source is almost identical, except for the references to script WebResources (script src=”/WebResource.axd?d=tpzArdJXo7erNNqm…), but the validators don’t fire and the controls have a different style.
Somewhere on the DevExpress website I read that WebResources may become inaccessible for some reason and that one should stop the IIS service, clear the Temporary ASP.NET files and the GAC cache, and restart. Restarting the IIS is out of question, and I refuse to believe that this is the only solution.
Any suggestions?
I’m using DevExpress version 10.1.7.0. This is the web.config:

Please open Handler Mappings property in the IIS settings of the web application’s and make certain that
AssemblyResourceLoader-Integrated and AssemblyResourceLoader-Integrated 4.0 has the request path equal to WebResource.axd
and
Type is System.Web.Handlers.AssemblyResourceLoader.
Also, please make certain that the Pipeline mode of the application’s Pool is set to the Integrated mode.
Olaf, your web.config file does not contain registration information about our http handler. To register ASPxHttpHandlerModule and enable its features, just place a DevExpress web control on the form or add specific code to the web.config file manually. For more information, see the How to manually register a HttpHandler Module topic.
