Implementing the backend service

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

1. From the context menu of the folder Services, click Add » Class...

2. Name the class file JobsBackendService.cs and click Add.

3. Open the file JobsBackendService.cs.

4. Add the following using statements:

   using System.Collections.Generic;

   using System.Linq;

   using Jobs.Model;

   using Jobs.Services.Data;

   using Telerik.Sitefinity.Modules;

   using Telerik.Sitefinity.Modules.GenericContent;

5. Make the JobsBackendService class inherit the ContentServiceBase<JobApplication, JobApplicationViewModel, JobsManager>class:

   public class JobsBackendService : ContentServiceBase<JobApplication, JobApplicationViewModel, JobsManager>

   {

   }

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

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

   {

       throw new NotSupportedException();

   }

    

   public override JobApplication GetContentItem(Guid id, string providerName)

   {

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

   }

    

   public override IQueryable<JobApplication> GetContentItems(string providerName)

   {

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

   }

    

   public override JobsManager GetManager(string providerName)

   {

       return JobsManager.GetManager(providerName);

   }

    

   public override JobApplication GetParentContentItem(Guid id, string providerName)

   {

       throw new NotSupportedException();

   }

    

   public override IEnumerable<JobApplicationViewModel> GetViewModelList(IEnumerable<JobApplication> contentList, ContentDataProviderBase dataProvider)

   {

       var viewModelList = new List<JobApplicationViewModel>();

       foreach (var product in contentList)

           viewModelList.Add(new JobApplicationViewModel(product, dataProvider));

       return viewModelList;

   }
