The resource class for this page was not found.

May 02, 2006 01:20 AM|LINK

Hi,

I've used resource files for localization in a web application and until this morning everything worked beautifully. This morning I had to move the application from one development machine to another (which as far as I can tell is configured identically), and now the application can't find any of the resource files for my user controls (.ascx). When you run the app, you get :

[InvalidOperationException: The resource class for this page was not found. Please check if the resource file exists and try again.]
   System.Web.Compilation.LocalResXResourceProvider.CreateResourceManager() +132
   System.Web.Compilation.BaseResXResourceProvider.EnsureResourceManager() +17
   System.Web.Compilation.BaseResXResourceProvider.GetObject(String resourceKey, CultureInfo culture) +17
   System.Web.Compilation.ResourceExpressionBuilder.GetResourceObject(IResourceProvider resourceProvider, String resourceKey, CultureInfo culture, Type objType, String propName) +20
   System.Web.UI.TemplateControl.GetLocalResourceObject(String resourceKey) +43
   controls_prtLogin.Page_Load(Object sender, EventArgs e) in c:\inetpub\wwwroot\steelgate\controls\prtLogin.ascx.vb:18
   System.Web.UI.Control.OnLoad(EventArgs e) +99
   System.Web.UI.Control.LoadRecursive() +47
   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Control.LoadRecursive() +131
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1061

and in the designer, you get the blue error line under the control declaration, and the error: "ASP.NET runtime error: '.', hexadecimal value 0x00, is an invalid character. Line 318, position 8."

I've tried everything I can think of including deleting all the resource files and starting new ones, but so far no luck. The thing that confuses me most is that it's only happening with the user controls...

Can anyone help?? Thank you!!!

Hi...

I encontered the same issue. I have a folder in my solution containing my user controls and a App_LocalResources folder to store their resources. I made modifications to a resource file in this folder and the application was not able anymore to access to the resources of all the controls.

[InvalidOperationException: The resource class for this page was not found. Please check if the resource file exists and try again.]

It takes me a while but I found a solution to bypass this problem. I simply need to do a modification on a ressource file in the App_LocalResources folder of the root (resources of the web pages).

It worked fine for me but why does this happens?

Hope it will help in some way...

Reboot

My co-worker Thilo experienced the same issue. After a simple reboot of the whole server (Windows 2003), the application just runs smooth again, without the error.

Probably the issue came up because we updated an existing and running application on the server. After a reboot the ASP.NET/.NET "engine" was freshly initialized. (A single "iisreset", without a reboot, did not help, though).

I experienced the same when I was playing around woth the resource files...

I could get it up and running by pressing "Rebuild Solution", that did the trick and I could browse my app again.

I have encountered the same problem and I am not sure what causes this. However, a fix that works for me is to copy the name of the control that caused the error from your resx file to your the resourcekey value in your aspx/ascx file will do the trick.
