Content Types (OrchardCore.ContentTypes)

View Components


Renders an editor to select a list of content types. It can optionally filter content types of a specific stereotype. The editor returns the selection as a string[] on the model.


Parameter Type Description
selectedContentTypes string[] The list of content types that should be marked as selected when rendering the editor.
htmlName string The name of the model property to bind the result to.
stereotype (optional) string A stereotype name to filter the list of content types available to select.


@await Component.InvokeAsync("SelectContentTypes", new { selectedContentTypes = Model.ContainedContentTypes, htmlName = Html.NameFor(m => m.ContainedContentTypes) })


Migration classes can be used to alter the content type definitions, like by adding new types, or configuring their parts and fields.


This service provides a way to modify the content type definitions. From a migrations class, we can inject an instance of this interface.

public class Migrations : DataMigration
    IContentDefinitionManager _contentDefinitionManager;

    public Migrations(IContentDefinitionManager contentDefinitionManager)
        _contentDefinitionManager = contentDefinitionManager;

    public int Create()
        // This code will be run when the feature is enabled

        return 1;

Creating a new Content Type

The following example creates a new Content Type named Product.


Changing the metadata of a Content Type

To change specific properties of the content type, an argument can be used to configure it:

_contentDefinitionManager.AlterTypeDefinition("Product", type => type
    // content items of this type can have drafts
    // content items versions of this type have saved
    // this content type appears in the New menu section
    // permissions can be applied specifically to instances of this type

Adding Content Parts to a type

The following example adds the TitlePart content part to the Product type.

_contentDefinitionManager.AlterTypeDefinition("Product", type => type

Each part can also be configured in the context of a type. For instance the AutoroutePart requires a Liquid template as its pattern to generate custom routes. It's defined in a custom setting for this part.

_contentDefinitionManager.AlterTypeDefinition("Product", type => type
    .WithPart("Product", part => part
        // sets the position among other parts
        // sets all the settings on the AutoroutePart
        .WithSettings(new AutoroutePartSettings { Pattern = "{{ ContentItem | display_text | slugify }}" })

For a list of all the settings each type can use, please refer to their respective documentation pages.

Adding Content Fields to a part

Fields can not be attached directly to a Content Type. To add fields to a content type, create a part with the same name as the type, and add fields to this part.

 _contentDefinitionManager.AlterTypeDefinition("Product", type => type
    .WithPart("Product", part => part
        .WithField("Image", field => field
            .WithDisplayName("Main image"))
        .WithField("Price", field => field

When added to a part, fields can also have custom settings which for instance will define how the editor will behave, or validation rules. Also refer to their respective documentation pages for a list of possible settings.
