New standardized format for content type localizations

In EPiServer 7.5, there is a new standarized way how to add localized texts for content types. In previous versions of EPiServer there was separate section for each content type, for instance:

<language id="en" name="English">
        <pagetype name="PageListBlock">
            <name>Page List</name>
            <description>Displays a list of pages, for example to display recent news</description>


Since the amount of “base” content types has grown significally in EPiServer 7.5, specifically when taking EPiServer Commerce into consideration, we decided to normalize how content localizations are handled. All content types are now added under the top level section named “contenttypes”. The format has also changed a bit as seen below:

<language id="en" name="English">
      <name>Standard Page</name>
      <description>A plain vanilla page.</description>
      <description>Used to insert a content teaser</description>


Adding localized texts for properties can be done either to a specific content type:

<language name="en">
      <name>Start page</name>
      <description>A description of the page type</description>
          <caption>Search Result Page Link</caption>
          <help>Link to search result page.</help>


Reusing localization for properties between content types

It is also possible to add common translations to an inherited type, for instance pagedata or icontentdata:

<language id="en" name="English">
          <caption>Disable indexing</caption>
          <help>Prevents the page from being indexed by search engines</help>
Note: If you have your own base classes that are not registered as content types and you want to add the translations to these classes you need to create a UIDescriptor for the base class.

Localizing headers

Headers (tabs for instance) can be localized in the top level section “groups”:

<language name="en">


Upgrading existing language files

When using Deployment Center to upgrade a site, the upgrade process will try to convert any xml files in the “lang” and “Resources\LanguageFiles” folders given that that process can write to these files (they cannot be read only for instance). If you have existing files in other locations or want to do the conversion manually for some reason (check in to source control for instance) there is a small program that can be used to convert existing files. Just select the folder where the files you want to convert are located and press “Convert Content Type Sections” and the files should be updated to use the new format. You can download the program here.

When I try to use PageData instead of icontentdata for reuse between contenttypes it doesn't seem to work.

Jan 7, 2014 11:44 AM

@Per: I tried using PageData instead of IContentData. It seems that this will work for some places (for instance when editing in the all properties view), but not for other places, like side by side editing and when hovering over a properties in the on page edit view. The reason why pagedata is not working but icontentdata is, is that the server only implements a hard coded fallback to icontentdata (when using PropertyDefinition.TranslateDisplayName). To use the full fallback chain we have to call a specific client side API which we are apparantly are not doing in all places at the moment. I'll report a bug for this.

Thanks for the answer.

Was there ever a separate blog post to describe how to make it work when inheriting own base classes? I can't seem to get EPI to pick up our translations no matter what I do. There seems to be a translation stored in the database that takes precedence but I can't find where it is...

I think that you need to create an UIDescriptor to indicate to the client that your base class should be taken into consideration. Just create and registering it should be enough:

public class YourBaseClassUIDescriptor : UIDescriptor

I can mention that I tried adding automatic registering for base classes. Unfortunately, this had some negative side effects so we had to back on this. We are trying other approaches to solve this so that you don't have to do this yourself.

I can add that the default convention is to use the classname made lower case as the key for the language files. This can be changed though, for instance including the full namespace, if you have classes with the same name in different namespaces. To do this, just set the LanguageKey property in the UIDescriptor for a type:

public class YourClassUIDescriptor : UIDescriptor
LanguageKey = typeof(YourClass).FullName.ToLowerInvariant();

@Linus: Ref your comment about filing a bug report 07 January 2014 11:44. Was this resolved? It seems this is still a problem i CMS 9.5. Localized (overridden) text is not shown on fly-out box, but in all properties view.

Hi, can you tell me how I can translate a name of my schedule job that extends ScheduledJobBase? Where should I put it in my xml file? What is the path?
