The example below demonstrates how to add values programmatically using a Razor view. However, this is used for illustrative purposes only and is not the recommended method for production environments.
@using Umbraco.Cms.Core.Services;
@inject IContentService Services;
@{
// Get access to ContentService
var contentService = Services;
// Create a variable for the GUID of the page you want to update
var guid = Guid.Parse("32e60db4-1283-4caa-9645-f2153f9888ef");
// Get the page using the GUID you've defined
var content = contentService.GetById(guid); // ID of your page
// Get the page you want to assign to the document picker
var page = Umbraco.Content("665d7368-e43e-4a83-b1d4-43853860dc45");
// Create an Udi of the page
var udi = Udi.Create(Constants.UdiEntityType.Document, page.Key);
// Set the value of the property with alias 'featurePicker'.
content.SetValue("featurePicker", udi.ToString());
// Save the change
contentService.Save(content);
}
Although the use of a GUID is preferable, you can also use the numeric ID to get the page:
@{
// Get the page using it's id
var content = contentService.GetById(1234);
}
If Modelsbuilder is enabled you can get the alias of the desired property without using a magic string:
@using Umbraco.Cms.Core.PublishedCache;
@using Umbraco.Cms.Core;
@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;
@{
// Set the value of the property with alias 'featurePicker'
content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x => x.FeaturePicker).Alias, udi.ToString());
}
See the example below to see how a value can be added or changed programmatically. To update a value of a property editor you need the .
The following example uses IPublishedSnapshotAccessor, which is obsolete in Umbraco 15 and will be removed in a future version. For more information, see the Version specific upgrades article.
