Posted by Community Admin on 07-Dec-2012 00:00

Hi,

I am using Following coding for get News Items, It's working fine.But I want filter the news items by Categories.

My Categories are,

Categories

1. News (Parent Category)
i) Singapore (Child Category)
ii) Internationl (Child Category)
2. News & Events,Errta (Parent Category)
i) Singapore (Child Category)
ii) Internationl (Child Category)

In above, I want fillter the news items for two types,
Type !: Fillter News Item which is under the News & Events,Errta (Parent Category) & Singapore (Child Category)

Type 2: Fillter News Item which is under the News & Events,Errta (Parent Category) & Internationl (Child Category)

In above operation how can I perform using code behind?

My NewsItems Collect Function...

var newsitems = App.WorkWith().NewsItems().Where(i => i.Status == Telerik.Sitefinity.GenericContent.Model.ContentLifecycleStatus.Live).Get().ToList();

foreach (var item in newsitems)

string Title = string.Empty;

string Summary = string.Empty;

DateTime dtPub;

Title = item.Title.ToString();

Summary = item.Summary.ToString();

dtPub = item.PublicationDate;

Hello,

If you want to programmatically filter news items based on categories, you can check the following code sample which will get all news items based on a category of your choosing.

public Taxon GetCategoryByTitle(string title)

var taxonomyMgr = TaxonomyManager.GetManager();

HierarchicalTaxonomy category = taxonomyMgr.GetTaxonomies<HierarchicalTaxonomy>().Where(x => x.Name == "Categories").SingleOrDefault();

if (category == null)

return null;

return category.Taxa.Where(x => x.Title == title).SingleOrDefault();

public List<NewsItem> GetContentByCategory(Guid categoryId)

Taxon catTaxon = GetCategoryByTitle("TestCategory1");

List<NewsItem> newsItemsList = GetContentByCategory(catTaxon.Id);

var taxonomyMgr = TaxonomyManager.GetManager();

var newsMgr = NewsManager.GetManager();

// Get the Id of the category

var taxonId = taxonomyMgr.GetTaxa<HierarchicalTaxon>()

.Where(t => t.Id == categoryId)

.SingleOrDefault()

.Id;

// Get all news items that are assigned to this category

var NewsItemsInCategory = newsMgr.GetNewsItems().Where(p => p.Status == ContentLifecycleStatus.Live && p.GetValue<TrackedList<Guid>>(

"Category").Contains(taxonId));

return NewsItemsInCategory.ToList();

and the list of used namespaces:

using Telerik.Sitefinity.GenericContent.Model;

using Telerik.Sitefinity.Modules.News;

using Telerik.Sitefinity.News.Model;

using Telerik.Sitefinity.Taxonomies;

using Telerik.Sitefinity.Taxonomies.Model;

using Telerik.Sitefinity.Model;

using Telerik.OpenAccess;

The GetValue method is part of the Telerik.Sitefinity.Model namespace.

You can further extend the sample to suit it to your needs.
