Resource file for MVCSiteMapProvider

Question

I'm using MVCSiteMapProvider for generating menus with localization for my application. My program works fine as long as the resource files for the menus are in the App_GlobalResources folder. When I move the resources into another folder, it gives an error mentioning not able to find the resources. I'm using $resources:Resource,menu_Home for accessing the resources in the MVC.sitemap file. I want to keep the resource files in a custom folder without storing them in the App_GlobalResources folder. Can anyone help?

I don't think this can be done, as this is done using the default localization feature built-in to the XmlSiteMapProvider in the .NET framework, see http://msdn.microsoft.com/en-us/library/ms178427(v=vs.100).aspx. But if that can be changed it would work. — Xharze, Jul 02 '12 at 11:01
I have the same problem. I cannot understand why it has not been workarounded, since resources in MVC applications are better placed elsewhere, but in App_GlobalResources, for testing purposes. — Jaime, Nov 20 '13 at 15:26

it happens because of the following code in MvcSiteMapNode.Title property:

var implicitResourceString = GetImplicitResourceString("title");
if (implicitResourceString != null && implicitResourceString == this["title"])
{
    return implicitResourceString;
}
implicitResourceString = GetExplicitResourceString("title", this["title"], true);
if (implicitResourceString != null && implicitResourceString == this["title"])
{
    return implicitResourceString;
}

In GetExplicitResourceString() method last parameter is true, which means throwIfNotFound. That's why exception is thrown. I fixed it by replacing the code above with the following code:

if (!string.IsNullOrEmpty(title))
{
    if (Provider.EnableLocalization)
    {
        try
        {
            if (!string.IsNullOrEmpty(title) && title.Contains("."))
            {
                int idx = title.LastIndexOf(",");
                string res = title.Substring(0, idx);
                string assembly = title.Substring(idx + 1);

                idx = res.LastIndexOf(".");
                string type = res.Substring(0, idx);
                string key = res.Substring(idx + 1);
                var rm = new ResourceManager(type, Assembly.Load(assembly));
                return rm.GetString(key);
            }
        }
        catch
        {
        }
        return title;
    }
}

And inside .sitemap file instead of title="$resources:Resource,Key" syntax use title="Namespace.Class.Property,Assembly" syntax which is more suitable when use use embedded resources with strong-type generated class.
