Hi everyone, I'm looking for some help. I've got a requirement to display a dropdown list of the types of Document Types / Pages that are available to filter by. Just now for example I have a list with

Article
Video
Podcast

And that works fine, it pulls back a Distinct list of types, however, I have a Document Type called Generic and on that docType I have a content picker which allows the user to select a Content Label, this should then override the Document Type and display on the dropdown list

So instead of

Article
Video
Podcast
Generic

It should show

Article
Video
Podcast
Interview

If interview was the label selected on the Generic Document Type.

Here is my code so far:

public ActionResult GetDistinctContentTypesForTopics(string topic)
    {

        var searcher = ExamineManager.Instance.SearchProviderCollection["ContentHubSearcher"];

        ISearchCriteria searchCriteria = searcher.CreateSearchCriteria(IndexTypes.Content);
        IBooleanOperation query = searchCriteria.GroupedOr(new string[] { "pagePostTags" }, topic);

        var queryResults = searcher.Search(query.Compile());
        IEnumerable<string> contentLabel = queryResults.Select(x => x["contentLabel"]).Distinct().ToList();

        List<string> contentLabelText = new List<string>();

// This gets the label if one is present, I should maybe check if it's of Type Generic too.
        if (contentLabel != null || contentLabel.Any())
        {
            foreach (var label in contentLabel)
            {
                var labelGuid = Umbraco.TypedContent(label);
                if (labelGuid != null)
                {
                    if(labelGuid.HasValue("labelTitle"))
                    {
                        var labelText = labelGuid.GetPropertyValue<string>("labelTitle");
                        contentLabelText.Add(labelText);
                    }       
                }
            }
        }


        // If nodeTypeAlias has Content Label, use that instead of nodeAlias
        var allSearchResults = queryResults.Select(x => x["nodeTypeAlias"]).Distinct().ToList();

        List<string> allResults = contentLabelText.Union(allSearchResults).Distinct().ToList();

        return PartialView("Topics/ContentTypesDropdown", allResults);


    }

I tried to do a union of the two lists that I have but that doesn't work because I'm guessing I'm still pulling back the Generic Document Type.

If anyone has some time to help me with this it would be amazing. It's Umbraco 7 project.

Thanks, O.
