How Do I Determine if a Document Has a Certain Category Assinged to it?

I'm assigning categories to the documents in my site and in code I want to determine if the current document has been assigned a certain category. In the code below everything works except that the ds.Contains() returns false even though the current document has the correct category (I verified it in debug mode) . What am I doing wrong?

InfoDataSet<CategoryInfo> ds = CategoryInfoProvider.GetDocumentCategories(CMSContext.CurrentDocument.DocumentID, null, null);
CategoryInfo myCategory = CategoryInfoProvider.GetCategoryInfo("TheCategory","MySite");

if (ds.Contains(myCategory))
{
//Do something.
}

Thanks,
Scott

RE:How Do I Determine if a Document Has a Certain Category Assinged to it?

Hi,

The relationship between a document and a category is represented by the DocumentCategoryInfo class. So, you can use the DocumentCategoryInfoProvider.GetDocumentCategoryInfo method to determine if the given document has been assigned to the category. Please take a look at the following code snippet:


            
using CMS.SiteProvider;
using CMS.TreeEngine;

CategoryInfo myCategory = CategoryInfoProvider.GetCategoryInfo("TheCategory", "MySite");

DocumentCategoryInfo dcInfo = DocumentCategoryInfoProvider.GetDocumentCategoryInfo(CMSContext.CurrentDocument.DocumentID, myCategory.CategoryID);

if (dcInfo == null)
{ 
    // document is not assigned to the category               
}

Best regards,
Michal Legen

Hi, You can register a custom macro method which determines if a document in question is assigned to some category. For more information I would like to point you to the following article: Registering cutom macro methods. Best regards, Michal Legen
