Create a custom Resource Class in Sitefinity

Create a custom Resource Class in Sitefinity


In Sitefinity it is possible to work with multilingual versions of your content. Pages, Blog posts, News items etc. When we create custom widgets, or just need to translate static text or labels on our pages, we can leverage the resource classes from within Sitefinity.

Sometimes we will need a Resource Class for our own set of widgets, or specific functionality. In these cases it becomes handy to create our own Resource Class which contains the predefined resources that we need inside our solution.

When this class exists and is properly registered in our Sitefinity system, we can maintain the resources throughout the Sitefinity back end.

So, to create a custom Resource Class, we will need to follow these steps:

  1. Create the custom Resource Class
  2. Add the predefined resources (if needed)
  3. Register the class during the Sitefinity initialization process

Create a custom Resource Class

So, to create a custom Resource class, we can simply add a new class to your Sitefinity project. We should make sure this class inherits from the Resource class, which can be found inside the Telerik.Sitefinity.Localization namespace. The following code represents a vanilla Resource class, to which we can add resources:

using Telerik.Sitefinity.Localization;
using Telerik.Sitefinity.Localization.Data;
namespace SitefinityWebApp.Resources {
[ObjectInfo(typeof(CustomResources), Title = "CustomResourcesTitle", Description = "CustomResourcesDescription")]
public class CustomResources : Resource {
   public CustomResources () {
   public CustomResources (ResourceDataProvider dataProvider)
      : base(dataProvider) {
   #region Class Description
   /// <summary>
   /// The title of this class
   /// </summary>
   [ResourceEntry("CustomResourcesTitle ", Value = "Custom Resources class", Description = "The title of this class.", LastModified = "2010/12/01")]
   public string CustomResourcesTitle {
      get { return this["CustomResourcesTitle "]; }
    /// <summary>
    /// The description of this class
    /// </summary>
   [ResourceEntry("CustomResourcesTitleDescription", Value = "Custom Resources class for Sitefinity", Description = "The description of this class.", LastModified = "2010/12/01")]
   public string CustomResourcesTitleDescription{
      get { return this["CustomResourcesTitleDescription"]; }


Add Resources to our class

Now that we have our class created, we can add some predefined resources into the class. Without these resources, this class will work without problems. The only thing is that you will then need to add resources through the backend interface. 

Predefined resources (properties) will come in handy when we create widgets or modules that we would like to distribute among multiple projects and want to allow users to create translations of labels and text inside those widgets or modules. To read how you can create a redistributable widget, see my other blogpost.

So a resource is actually just a property inside this class. It looks like this:

#region Resources
/// <summary>
/// Twitter Widget Title
/// </summary>
[ResourceEntry("CustomResourceLabelTitle", Value = "Title", Description = "The title of a label.", LastModified = "2010/12/01")]
public string CustomResourceLabelTitle{
   get { return this["CustomResourceLabelTitle"]; }


We can add as many resources to the class, as we would need.

Register our new Resource Class

To get this new Resource Class to work, we need to register it inside our application initialization. A common place to do this, is inside our Global.asax file:

protected void Application_Start(object sender, EventArgs e) {
   Bootstrapper.Initialized += new EventHandler<Telerik.Sitefinity.Data.ExecutedEventArgs>(Bootstrapper_Initialized);
void Bootstrapper_Initialized(object sender, Telerik.Sitefinity.Data.ExecutedEventArgs e) {
   // Register any Resource classes


When we restart our application, the class will be registered and actually become available inside our Resource classes list that we can find in the Sitefinity backend. (Labels & Messages)

Sitefinity Resource classes

Now when we add new resources through the back-end, we can point to our newly created Resource Class, and also use this resources in our templates and code.

Add new label in Sitefinity


When the Resources are translated, or when new Resources are added through the backend, a physical file will be created under /App_Data/Sitefinity/GlobalResources, so be sure to deploy those files also when you move your site from Development to Production.
