How to get all possible values of a TaxonomyField?

Question

I found the GetFieldValue(string value) function but this requires that you pass it a value that serves as the identifier for the value to be retrieved (i think).

I just want to get all of the possible values for the TaxonomyField, can this be done?

Answer 1

If you want to get all the possible values for a TaxonomyField, you can use a method similar to this:

  private TermCollection GetAllValuesForField(SPWeb spWeb, SPList spList, string fieldDisplayName)
    {
        // create new TaxonomySession based on the current Site
        TaxonomySession taxonomySession = new TaxonomySession(spWeb.Site);

        // connect to the Term Store
        TermStore termStore = taxonomySession.TermStores["Term Store Name"];

        // connect to the Term Store Group
        var group = termStore.Groups["Term Group Name"];

        // get a reference to the TaxonomyField (I'm using a TaxonomyField in a SharePoint List)
        TaxonomyField taxField = spList.Fields[fieldDisplayName] as TaxonomyField;

        // get the term set based on the ID (from the taxonomy field)
        var termSet = group.TermSets[taxField.TermSetId];

        return termSet.GetAllTerms();
    }

Answer 2

Yes, that can be done. You need to know the term set to which your TaxonomyField is associated. You can then read all the terms (in other words, all possible values for your taxonomy field) that belong to the term set.
