    CustomLabel Examine example

    I wanted to share my /MacroPartial Custom Label code because I was able to greatly improve the performance of the admin by switching from calling the ContentService.GetById(key) for every option in the NuPicker, to using the Examine InternalIndexer instead.  I was rendering 500+ items per NuPicker.  Some doctypes had 2-3 NuPickers, and the real killer was putting a NuPicker in an Archetype datatype which let the admin users dynamically add as many as they wanted to the node!  10 pickers each loading 600+ options from the DB --> bad performance, even some locking of the web server.

    Bad way:

    IContent ic = ApplicationContext.Services.ContentService.GetById(Convert.ToInt32(Model.MacroParameters["key"]));

    Good way:
        var intSearchProvider = ExamineManager.Instance.SearchProviderCollection["InternalSearcher"];
        var criteria = intSearchProvider.CreateSearchCriteria("content");
        var filter = criteria.Id(Convert.ToInt32(Model.MacroParameters["key"]));
        var results = intSearchProvider.Search(filter.Compile());
        if (results.Any())
            var result = results.First();
            string alias = result.Fields["nodeTypeAlias"].ToUpper();
            string name = result.Fields["nodeName"];
            <span>@(alias + ": " + name)</span>

    Thanks for sharing :) the ContentService hits the database, but how about using:

    IPublishedContent content = UmbracoHelper.TypedContent(Convert.ToInt32(Model.MacroParameters["key"]))

    This NuPicker options needs to include unpublished content, which AFAIK, there is no cached API to query, hence the Examine technique.
