Learn more about the default property editors that ships with an Umbraco installation.
A Property Editor is the editor that a Data Type references. A Data Type is defined by a user in the Umbraco backoffice and references a Property Editor. In Umbraco a Property Editor is defined in a JSON manifest file and associated JavaScript files.
Are you looking for the Grid Layout or Nested Content?
The following Property Editors have been removed with the release of Umbraco 14:
Grid Layout
Nested content
We recommend using the Block Editor or the Rich Text Editor Blocks instead.
When creating a Data Type, specify the property editor for the Data Type to use by selecting from the "Property editor" list (as shown below).
Umbraco comes pre-installed with many useful property editors.
Returns: MediaWithCrops
Returns a path to an image, along with information about focal point and available crops.
When the Image Cropper is used on a Media Type the crops are shared between all usages of a Media Item. This is called global crops.
If the Image Cropper is used on a Document Type, the file and crops will be local to the Document.
Notice that it is possible make local crops on shared Media Items via the Media Picker Property Editor.
You can add, edit & delete crop presets the cropper UI can use.
The Image Cropper provides a UI to upload an image, set a focal point on the image, and use predefined crops.
By default, images in the Image Cropper will be shown based on a set focal point and only use specific crops if they are available.
The Image Cropper comes with 3 modes:
Uploading an image
Setting a focal point
Cropping the image to predefined crops
The editor exposes a drop area for files. Select it to upload an image.
By default, the Image Cropper allows the editor to set a focal point on the uploaded image.
All the preset crops are shown to give the editor a preview of what the image will look like on the frontend.
The editor can fit the crop to the image to ensure that the image is presented as intended.
ImageSharp.Web is image processing middleware for ASP.NET.
We bundle this package with Umbraco and you can therefore take full advantage of all its features for resizing and format changing. Learn more about the built in processing commands in the official ImageSharp documentation.
The Image Cropper comes with an API to generate crop URLs. You can also access the raw data directly as a dynamic object.
For rendering a cropped media item, the .GetCropUrl
is used:
The third parameter is HtmlEncode
and is by default set to true. This means you only need to define the parameter if you want to disable HTML encoding.
Or, alternatively using the MediaWithCrops
extension method:
Set the htmlEncode
to false so that the URL is not HTML encoded
To update a content property value you need the Content Service.
The following sample demonstrates how to add or change the value of an Image Cropper property programmatically. The sample creates an API controller with an action, which must be invoked via a POST request to the URL written above the action.
If you use Models Builder to generate source code (modes SourceCodeAuto
or SourceCodeManual
), you can use nameof([generated property name])
to access the desired property without using a magic string:
Crop URLs are not limited to usage within a view. IPublishedContent
has a GetCropUrl
extension method, which can be used to access crop URLs anywhere.
The following sample demonstrates how to use GetCropUrl
to retrieve URLs for all crops defined on a specific image:
