DotNetNuke Resources keys

In DotnetNuke Localization support, every resource key (in APP_LocalResources or APP_GlobalResources) should end with an extension.
resourceName.Text – Represents a string used for a common purpose
resourceName.Help – Used mostly in conjuncture with the DNN:Label control, which supplies a help icon () and tooltip.
resourceName.Tooltip – Used for a control’s Tooltip property.
resourceName.Action – Used to represent the Title property of a ModuleAction item shown in an actions menu.
resourceName.Confirm – Text that is displayed in a JavaScript’s confirmation dialog (such as a dialog to confirm deleting a module).
resourceName.Error – Text that is displayed as an error message. This might be for a label or, more commonly, for one of the ASP.NET validation controls.
resourceName.Detail – Text that gives more detail about an error message.

If we add a resource key in a resx file of the APP_LocalResources or APP_GlobalResources and didn’t give it an extension (like one of the above or any other one), we cannot get its value back by the DNN Localization logic of the:

DotNetNuke.Services.Localization.Localization.GetString(key, this.LocalResourceFile);

Or:

DotNetNuke.Services.Localization.Localization.GetString(key, <global resource file name>);

Further, if we call the Localization.GetString function with a key without an extension, it will assume that we are asking about the one with the extension “.Text”.
So the call of

Localization.GetString("SomeKey", LocalResourceFile)

is equivalent to:

Localization.GetString("SomeKey.Text", LocalResourceFile)

Localization support in DotNetNuke

In general, DNN disables the ASP.NET localization (the resources files) by disabling the build providers of the extensions (.resx and .resources) in the web.config.

<buildProviders>
  <remove extension=".resx"/>
  <remove extension=".resources"/>
</buildProviders>

So the calls of HttpContext.GetGlobalResourceObject() and HttpContext.GetLocalResourceObject() will always return null!

If we need to support localization in DNN solutions, we have to use the DNN localization class (DotNetNuke.Services.Localization.Localization) to do so.
