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 Content Service.
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 ContentServicevar contentService = Services; // Create a variable for the GUID of the page you want to updatevar guid =newGuid("796a8d5c-b7bb-46d9-bc57-ab834d0d1248"); // Get the page using the GUID you've definedvar content =contentService.GetById(guid); // ID of your page // Set the value of the property with alias 'myCheckBox'content.SetValue("myCheckBox",true); // Save the changecontentService.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 idvar 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;@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;@{ // Set the value of the property with alias 'myCheckBox'content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor,x =>x.MyCheckBox).Alias,true);}
