Category for the current NewsItem

Posted by Community Admin on 19-Oct-2010 00:00

Hi,
I've created a Page "NewsMain" which contains the built-in news content widget. There are a couple of category classifications (Taxonomy) for the News Items. In my own, custom widget, how can I get the category associated with the current NewsItem list or the category for the current news item?

For example - this is the root news page:
http://sf4website/NewsMain/ - it contains my custom widget and I want to get the categories associated with the newsitems here.
And this is the news details page -
http://sf4website/newsmain/2010/10/15/FirstNewsPageTest/ - I want to get the category here also.
Is there any method which I can use to get the current categories? I've searched the documentation and the forums, but I coudn't find any.

Hi,
I've managed to find the category for the currently loaded news item. This is the code which I use to get the first category for a given News item:

01.private HierarchicalTaxon GetFirstCategory(TaxonomyManager taxonManager)

02.

03. // get the first category for the current item

04. HierarchicalTaxon firstCategory = null;

05. NewsManager cntManager = NewsManager.GetManager();

06. string urlParameterString = this.GetUrlParameterString();

07. string redirectUrl;

08. if (!string.IsNullOrEmpty(urlParameterString))

09.

10. NewsItem item = cntManager.GetItemFromUrl<NewsItem>(urlParameterString, out redirectUrl);

11. if (item != null)

12.

13. IList<Guid> categoryIds = (IList<Guid>)item.GetValue("Category");

14. Guid firstCategoryId = categoryIds.FirstOrDefault();

15. if (Guid.Empty != firstCategoryId)

16.

17. firstCategory = taxonManager.GetTaxon<HierarchicalTaxon>(firstCategoryId);

18.

19.

20.

21.

22. return firstCategory;

23.

Hi Vladimir,

You might also find these posts useful

Currently the only way to get a category for an item is through the DataExtensions methods.
