Question

I’m using explicit localization in my pages, like in:

<asp:Literal ID="appTitle" runat="server" Text="<%$ Resources:TranslationResource, AppTitle %>"></asp:Literal></div>

If the AppTitle resource does not exist, is there any way to avoid “parser error” and to show a empty string or the resource name?

Thanks in advance.

Answer 1

You could use GetGlobalResourceObject, which does the same thing but returns null, rather than throwing an exception, if the key does not exist.

<div><%= GetGlobalResourceObject("TranslationResource", "AppTitle") %></div>

You can easily add a fallback value using the null-coalescing operator:

<div><%= GetGlobalResourceObject("TranslationResource", "AppTitle") ?? "No translation resource" %></div>

If you need to modify the behavior of the localization provider in a centralized way (without needing to modify the syntax used in the pages), you can override resourceProviderFactoryType. Add the type to the web.config globalization section …

<globalization resourceProviderFactoryType="MyLocalizationProvider"/>

And create MyLocalizationProvider by sub-classing ResourceProviderFactory.
