Using SharePoint site’s Regional Settings as your UICulture for WCM presence sites.

This post describes how I use resource files in SharePoint on the custom created publishing pages and DVWP web-parts. The solution provided uses the standard <%resources … %> tag and reads the culture from the regional settings then uses this culture to load the resource file from the APP_GLOBAL_RESOURCES and display the localized text. Therefore enabling to display localized static text to users on a per-site-basis.

I am using variations as a part of an solution for a client. I’ve created quite a lot of web-parts in using the DVWP SharePoint designer, layout pages and master-pages. At some point I needed to localize the static text’s on the pages. The requirements stated that the resources language used on the sites should be on a per-site-basis (such as contact form for nl-NL/de-DE), and had to be made possible to switch it afterwards. The authoring environment or back-end (such as lists etc) should be in English. The first thing that popped in my head was the use of resource functionality provided by the SharePoint or actually ASP.NET framework itself. In this way I could just use the OOB <%$Resources: MyFile, MyKey %> functionality provided by ASP.NET.

1. Creating the resource file for translation
This is pretty straightforward, just create your resources files such as. MyFile.nl-NL.resx, and MyField.de-DE.resx etc. NOTE: don’t forget to alter the localeID between the comments. This is essential if you want SharePoint to pick up the locales.

2. Deploying your resource files to the app_globalresources.
However, to get the resources loaded, files needed to be placed in the “app_globalresources” in the IIS directory of the web site. This can be done manually, but since this requires copy pasting by inferior humans such as I, it is a risk we can’t take (And it would be a showstopper in our automatic build). So we’ll do it by featuring. Unfortunately there is no default way of provisioning this directory using feature functionality out of the box.  Luckily, using SharePoint’s extensive object model and feature receiver API we can create our own logic for copying the resources to the IIS “app_globalresources” directory as pointed out by this post. However, I adapted it slightly to support retracting of resource files, but the main functionality kept intact.

3. Making SharePoint use the regional settings as your culture for displaying publishing pages.
So I created a couple of resource files, in different locale’s but SharePoint didn’t pick it up when I changed the regional settings. This is because ASP.NET uses UICulture for loading resources instead of the Culture setting and ignores the Regional Settings. To bend SharePoint to our will. I derived a class from PublishingPageLayout override the PreInit and the IntializeCulture culture to set the the:

CurrentThread.Current.UICulture = SPContext.Current.Web.Locale.

I used my own PublishingPageLayout (made it RegionalAwarePublishingPageLayout) and used this instead of the original PublishingPageLayout that is used for creating page layouts. This way, SharePoint uses my RegionalPublishingPageLayout implementation instead of its own.

And there you go! Now you can use the standard resources approach in SharePoint, and let SharePoint load the correct language by reading from the Regional Settings.
