Implementing the backend service

To create the backend service, you must perform the following:

1. From the context menu of the folder Web » Services in the LocationsModule project, click Add » Class.
2. Name the class file LocationsBackendService.cs and click Add.
3. Open the file LocationsBackendService.cs.

4. Add the following using statments:

   • using Telerik.Sitefinity.Modules;
   • using LocationsModule.Model;
   • using LocationsModule.Web.Services.Data;
   • using LocationsModule.Data;
   • using Telerik.Sitefinity.Modules.GenericContent;

5. Make the LocationsBackendService class inherit the ContentServiceBase<LocationItem, LocationItemViewModel, LocationsManager> class:

   public class LocationsBackendService : ContentServiceBase<LocationItem, LocationItemViewModel, LocationsManager>

   {

   }

6. Implement the abstract members of the ContentServiceBase in the following way:

   public override IQueryable<LocationItem> GetChildContentItems(Guid parentId, string providerName)

   {

       throw new NotImplementedException();

   }

    

   public override LocationItem GetContentItem(Guid id, string providerName)

   {

       return this.GetManager(providerName).GetLocation(id);

   }

    

   public override IQueryable<LocationItem> GetContentItems(string providerName)

   {

       return this.GetManager(providerName).GetLocations();

   }

    

   public override LocationsManager GetManager(string providerName)

   {

       return LocationsManager.GetManager(providerName);

   }

    

   public override LocationItem GetParentContentItem(Guid id, string providerName)

   {

       throw new NotImplementedException();

   }

    

   public override IEnumerable<LocationItemViewModel> GetViewModelList(IEnumerable<LocationItem> contentList, ContentDataProviderBase dataProvider)

   {

       var list = new List<LocationItemViewModel>();

    

       foreach (var location in contentList)

           list.Add(new LocationItemViewModel(location, dataProvider));

    

       return list;

   }
