The Member Group Picker opens a panel to pick one or more member groups from the Member section. The value saved is of type string (comma separated IDs).
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 'memberGroup'. The value is the specific ID of the member groupcontent.SetValue("memberGroup",1067); // Save the changecontentService.Save(content);}
You can also add multiple groups by creating a comma separated string with the desired member group IDs.
@{ // Set the value of the property with alias 'memberGroup'. content.SetValue("memberGroup","1067","1068");}
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;@using Umbraco.Cms.Core;@inject IPublishedSnapshotAccessor _publishedSnapshotAccessor;@{ // Set the value of the property with alias 'memberGroup'content.SetValue(Home.GetModelPropertyType(_publishedSnapshotAccessor, x =>x.MemberGroup).Alias,1067);}
