    Getting Descendants from Root node

    I'm trying to get all descendants of the rootnode (or any node for that matter) from my UmbracoApiController, filtered with Linq.

    So basicly what I would want to do is:

    rootnode.Descendants(a => a.DocumentTypeAlias == "myDocType" && a.Name == "myName")
    

    This is documented at: https://our.umbraco.org/Documentation/Implementation/Routing/MVC/querying

    But somehow, when I select the rootnode form the UmbracoApiController, my IPublishedContent object doesn't have a Descendants() method.

    var root = Umbraco.TypedContentAtRoot().First();
    

    It does have a Children property, but obviously this only returns all the direct children, and not all descendants.

    How else am I able to select all documents, filtered by DocumentTypeAlias, and probably also by other properties (CreatedAt for example)?

    Hi

    it should have decendants ...

    root.Descendants().Where(x => x.DocumentTypeAlias == "someDocType"); 
    

    things to check.

    1. Visual studio 2015 - doesn't do intellisense properly for Umbraco (pre v7.3) - it's an MVC4 / 5 thing, but that might be why you can't see it?

    2. Inheritance - my views are using

      @inherits Umbraco.Web.Mvc.UmbracoTemplatePage

    if you're inheriting from a model again Intellisense (and the site) might not work.

    however, if you want to do things sitewide, i would say have a look at examine, getting nodes of type across a whole site can take some time, using examine is slightly more complex but way faster.

    failing that cache the macro or partial view because that will make it quick too.

    I do using Visual Studio 2015, but it's not compiling, so IDE should'nt matter.

    I managed to fix this however by using the UmbracoHelper

    var umbracoHelper = new UmbracoHelper(UmbracoContext.Current);
    var blogs = umbracoHelper.TypedContentAtRoot().First().Descendants("Blog").ToList();

    I ran into the same issue, turns out I was missing a using statement. I had

    using Umbraco.Web.Mvc;
    

    But also needed to have

    using Umbraco.Web;
    

    Then the descendants option showed up.
