ASP.net 2.0 navigation control Treeview,menu and so on under the virtual host error

asp.net|treeview| Navigation | control | Virtual host the days when a Web site was deployed to a virtual host, the TreeView and menu controls were found to be problematic. Began to think is not to add aspnet_client to the Wwwroot directory, contact the service provider to help me add, the problem remains.
So search for the reason, found that 2.0 using a WebResource.axd resource mapping, so added <add path= "WebResource.axd" verb= "Get" type= "System.Web.Handlers.AssemblyResourceLoader" validate= "True"/>
Is the service provider not adding an extension to the. Axd? Then contact the service provider to increase the expansion, problem solving.
Executable file: C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll
Extension:. axd
Limit to: Get,head,post,debug
and remove the "Confirm file exists" tick.
