    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.

    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.           }
    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.
    Best wishes,
