We have moved!

You are currently looking at documentation for Umbraco 8 and older versions.
An automated guess is that docs.umbraco.com/umbraco-cms/reference/templating/mvc/querying could be the link to the new documentation for Umbraco 9 and newer versions.

    Querying & Traversal

    This section will describe how you can render content from other nodes besides the current page in your MVC Views

    Querying for content and media by id

    The easiest way to get some content by Id is to use the following syntax (where 1234 is the content id you'd like to query for):

    // to return IPublishedContent
@Umbraco.Content(1234)

    You can also query for multiple content items using multiple ids:

    // to return the strongly typed (IEnumerable<Umbraco.Core.Models.IPublishedContent>) collection
@Umbraco.Content(1234, 4321, 1111, 2222)

    This syntax will support an unlimited number of Ids passed to the method.

    You can also retrieve content using the Guid Id. In the example "ca4249ed-2b23-4337-b522-63cabe5587d1" is the key of the content.

    // to return the Umbraco.Core.Models.IPublishedContent
@Umbraco.Content(Guid.Parse("ca4249ed-2b23-4337-b522-63cabe5587d1"))

    You can also pass a Udi to retrieve the content.

    // to return the Umbraco.Core.Models.IPublishedContent
@Umbraco.Content(Udi.Create("document", Guid.Parse("ca4249ed-2b23-4337-b522-63cabe5587d1")))

    The same query structures apply to media:

    @Umbraco.Media(9999)
@Umbraco.Media(9999,8888,7777)
@Umbraco.Media(9999)
@Umbraco.Media(9999,8888,7777)
@Umbraco.Content(Guid.Parse("ca4249ed-2b23-4337-b522-63cabe5587d1"))
@Umbraco.Content(Udi.Create("media", Guid.Parse("ca4249ed-2b23-4337-b522-63cabe5587d1")))

    Traversing

    All of these extension methods are available on Umbraco.Core.Models.IPublishedContent so you can have strongly typed access to all of them with intellisense for both content and media. The following methods return IEnumerable<IPublishedContent>

    Children() // this is the same as using the Children property on the content item.
Ancestors()
Ancestors(int level)
Ancestors(string nodeTypeAlias)
AncestorsOrSelf()
AncestorsOrSelf(int level)
AncestorsOrSelf(string nodeTypeAlias)
Descendants()
Descendants(int level)
Descendants(string nodeTypeAlias)
DescendantsOrSelf()
DescendantsOrSelf(int level)
DescendantsOrSelf(string nodeTypeAlias)
Siblings()
SiblingsAndSelf()

    Additionally there are other methods that will return a single IPublishedContent

    Ancestor()
AncestorOrSelf()
AncestorOrSelf(int level)
AncestorOrSelf(string nodeTypeAlias)
AncestorOrSelf(Func<IPublishedContent, bool> func)

    Complex querying (Where)

    With the IPublishedContent model we support strongly typed LINQ queries out of the box so you will have intellisense for that.

    Some examples

    Where children are visible

    @Model.Children.Where(x => x.IsVisible())

    Traverse for sitemap

    var items = @Model.Children.Where(x => x.IsVisible() && x.Level <= 4)

    The two examples below have not been verified for Umbraco 9 and 10 yet.

    therefore they might not work on the latest versions of Umbraco.

    Content sub menu

    @Model.AncestorOrSelf(1).Children.Where(x => x.DocumentTypeAlias == "DatatypesFolder").First().Children

    Complex query

    With the strongly typed IPublishedContent you can do complex queries.

    // This example gets the top level ancestor for the current node, and then gets
// the first node found that contains "1173" in the array of comma delimited
// values found in a property called 'selectedNodes'.

var result = @Model.Ancestors().OrderBy(x => x.Level)
    .Single()
    .Descendants()
    .FirstOrDefault(x => x.GetPropertyValue("selectedNodes", "").Split(',').Contains("1173"));
